The Role of a Lubrication System in Extending Hydraulics Lifespan

In the world of machinery, a critical component for the optimal function and longevity of hydraulic systems is a well-maintained lubrication system. Hydraulic systems are the workhorses, powering everything from construction equipment to factory robots, exerting immense force with precision. But just like any hardworking machine, hydraulic systems require proper care to function optimally and reach their full lifespan. Here's where the often-overlooked hero comes in: the lubrication system.

Understanding Hydraulics

Industrial hydraulic systems rely on a pressurized fluid, typically oil, to transfer power. This fluid transmits force through interconnected cylinders and actuators, performing various tasks. However, this pressurized fluid also creates friction between moving components. Here's where lubrication comes in.

The Magic of Lubrication

A well-designed lubrication system delivers a thin film of oil to critical components within the hydraulic system, including pumps, valves, and cylinders. This film serves several crucial functions:

Friction Reduction: By creating a slippery barrier, lubrication minimizes friction between metal components. This reduces wear and tear, extending the lifespan of pumps, valves, and other parts. Less friction also translates to improved system efficiency, as less energy is wasted overcoming resistance.

Heat Dissipation: Hydraulic systems generate heat due to friction and fluid pressure. Lubrication helps transfer this heat away from critical components, preventing overheating and potential component failure. Cooler operating temperatures contribute to overall system reliability.

Contamination Control: Lubricating oil acts as a barrier, preventing dirt, dust, and other contaminants from entering the system. These contaminants can cause abrasive wear, clog valves, and hinder system performance. A clean hydraulic system is a happy and long-lasting hydraulic system.

Corrosion Protection: Lubricating oil often contains anti-corrosion additives that form a protective layer on metal surfaces. This reduces the risk of rust and corrosion, which can damage components and lead to leaks.

Types of Hydraulic Lubrication Systems

There are various lubrication system designs for hydraulics, each suited to specific applications. Here are some common types:

Splash Lubrication: In simpler systems, components might rely on splashing oil within the reservoir to achieve lubrication.

Pressure Lubrication: More sophisticated systems employ dedicated pumps that deliver oil under pressure to critical components. This ensures a consistent and reliable flow of lubrication.

Metered Lubrication: High-performance systems might utilize precisely metered lubrication, delivering the exact amount of oil needed for each component. This optimizes lubrication efficiency and minimizes oil waste.

Consulting with a qualified hydraulics specialist is recommended to ensure you have the right system in place. So, the next time you witness the impressive feats of hydraulic power, remember the silent hero behind the scenes – the lubrication system, keeping everything running smoothly.

Precautions for centrifugal pump testing

After the installation of various centrifugal pump products newly purchased and installed, it is necessary to conduct centrifugal pump testing work in advance. When conducting centrifugal pump testing work, the following methods and precautions for centrifugal pump testing should be followed 1. Before starting the centrifugal pump, it is prohibited to conduct idle and no-load testing. Liquid testing should be carried out according to the operating procedures specified in the centrifugal pump operating instructions. For the forced lubrication system, the temperature rise of the centrifugal pump bearing oil should not exceed 28 degrees, and the temperature of the bearing metal should be less than 93 ℃. 2. For centrifugal pumps with oil ring lubrication or splash lubrication systems, the temperature of the lubricating oil should not exceed 39 degrees, and the temperature of the bearing components should be less than 82 degrees. 3. When testing the centrifugal pump, the vibration value of the centrifugal pump bearing should also be checked. The vibration standard of the centrifugal pump bearing can refer to the relevant vibration standards of petrochemical rotating machinery. 4. During the testing process of the centrifugal pump, the operation of the centrifugal pump should be very balanced and noise free. The coolant and lubricating oil system should be normal, and there should be no leakage in the centrifugal pump and its auxiliary pipelines. 5. During the process of testing the centrifugal pump, attention should be paid to whether the current of the centrifugal pump motor is operating within the specified range. If the current exceeds the specified range, it indicates that the actual operating head is lower than the pump head. In this case, it is recommended to turn down the outlet valve to control the flow of the centrifugal pump and use it within the rated current range. 6. The leakage of various seals and media in centrifugal pumps shall not exceed the following standard requirements: (1) Clean water centrifugal pump with mechanical seal: 10 drops/min for light oil and 5 drops/min for heavy oil (2) Multi stage centrifugal pump products sealed with packing: 20 drops/min for light oil and 10 drops/min for heavy oil (3) For magnetic drive pumps conveying toxic, harmful, flammable, and explosive media, no obvious visible leakage is allowed.

Make me a mechanic

The workshop for the bike mechanic course is tucked in an estate off Caledonian Road. I arrive on The Beast, my much-used tourer of six years. Its frame is peppered with scratches and there’s a small dent from where, I guess, someone tried to steal it. Never has it had a full service.

The course tutor is David, an aviation engineer turned bike mechanic. David’s perceptions are grounded in physics. He is wedded to rules, logic and formulas: there’s always a right or wrong, a yes or a no in David’s world. Dissembling and reassembling objects are second nature to him, something I’ve never experienced. Still, over the next two days, David attempts to impart this approach to me as I get hands on with the bike.

And I’m curious to learn. A long-term cyclist, I can still only do the basics (i.e. fix a puncture, replace a chain): anything that involves cables continues to daunt me. I’m here also for professional reasons. I work part-time at Wheely Tots, a charitable cycling start up. While my job is largely desk-based, better knowing my way around a bike will undoubtedly support my work.

My fellow students hope to use the course to encourage others to get on their bike as Wheely Tots’ ambassadors and freelancers: Jimmy, a health support worker, Armagan, a yoga teacher, Ana, a Montessori educator, and Gail, a Wheely Tots’ session leader and cycling instructor with 20 years’ experience.

We gather round David as he explains the course set up. I get the impression that the workshop is his sanctuary. The walls are lined with tools, each with a place of their own. Strip lighting bounces off the pristine metal worktops. Down the middle is a row of bikes on stands: bikes that remain in this strip-lit environment, never to be splashed with mud or rain. Tyres that don’t meet tarmac or grass. Instead, hand after amateur hand fiddle with these bikes, eyes under furrowed brows study their parts, trying to figure out how they work.

It is on these bikes that I index gears, remove a tyre without tyre levers, take off and put on a chain, attempt to true a wheel (so hard!), take out and replace ball bearings in a wheel, adjust brakes and check a headset.

It’ll take me a few more goes to really embed these skills into my muscle memory. But here are some of my points of learning, aimed mainly at my fellow novices. They come with the caveat that the bike mechanic in your life may well contest them:

Don’t use M*ck Off to clean your bike. Apparently the fish don’t like it and washing up liquid is gentler on the environment and just as good.

David recommended cleaning your chain every 60 to100 miles. There’s such a thing as a chain cleaner, though I tend to use an old toothbrush.

On the topic of chains, it’s easy to mis-grease them. Rather than drenching the whole thing in lubricant, grease the bits between the links and wipe off excess with a clean rag. Also, you’re aiming for the parts of the chain that connect with the sprockets (the metal discs with teeth that the chain sits on), so better to grease along the top of the lower part of the chain. According to David, rapeseed oil is up to the task.

I finally learnt what a group set is (basically brakes, gears, chain, cranks, and all the connecting cables). Armagan poetically described it as the bike’s nervous system, while the frame is its skeleton.

When you look at the cassette (the collection of sprockets your chain moves up and down on), you can think of it as a mountain: high (gears) at the top, low (gears) at the bottom. As a person who does not retain this vocabulary without an aide memoire, this is really helpful for me.

The adage ‘rightly tightly, lefty loosey’ left me in a confused, frustrated mess at times, because whether you go right or left depends on the position of your hand. Better for me to think clockwise to tighten, anticlockwise to loosen.

Precision is pretty important. Though my brother, a bike mechanic, dismissed the need for torque wrenches.

On that note, being an effective mechanic is less about strength and more about being tuned into your senses. “Soft hands,” David kept saying. Incremental adjustments can be all that you need. In fact, the fewer unnecessary twists and turns you perform on your bike, the less wear and tear its components will sustain. Makes sense.

This is a good place to go for sound information, albeit Shimano-centric. (David doesn’t tolerate much of ‘the rubbish on YouTube’)

Since doing the course, I’ve conducted an informal survey with a few of my friends (all male interestingly) about their approach to bike mechanics. They alll freely admit that they’ve not known exactly what they’re doing when they’ve attempted to fix or service their bikes. This has led to them making some pretty fundamental mistakes, but is equally how the learning’s stuck. At one point, as I worked away at the gears, doubting my ability, David gave me some feedback and said, “We’ll make a mechanic out of you.” It’s not an innate skill: it’s about confidence and practice.

I also have a renewed connection with The Beast. Each time David introduced a topic – the importance of a clean chain, brake adjustments - my thoughts would stray to my bike and I would add another item to a mental to do list. I feel like I understand the machine better and therefore - fingers crossed - I won’t allow niggles to persist for as long as I previously have. And maybe I’ll finally replace that saddle.

MOPAR FLATHEADS

(taken from ‘49plymouth.com)

Valves

The valve train is lubricated entirely by the splash effect of the camshaft and valve train. The only pressure feed to the system is to the cam bearings. The oil that escapes the camshaft journals and any splash resulting inside the crankcase from the reciprocating crank mass are the sole source of lubrication for cam followers, springs and valve guides.

Common sensed says that exhaust valves and guides run at a higher temperature than intake valves and guides. Coupled with this temperature differential is the fact that intake guides are subjected to manifold vacuum, (meaning that they tend to suck oil into the guide), while exhaust guides work in the environment of exhaust pressure and heat. These two facts, temperature and pressure, mean that exhaust guides get virtually no lubrication. As a result of this fact, they are one of the more likely components in the valve train to wear out first.

Having said this, a quick look at these engines shows that they, like most automotive engines, sit high in the front. This means that in a splash lubricated valve train, the highest component is also the farthest from the source of splash lubrication – the cam bearings and followers.

Happenstance (and perhaps MoPar engineering) have dictated that the frontmost engine valve in MoPar flathead engines is an exhaust valve – the ones that wears first, anyhow. All this combines to mean that the front valve guide is the hottest, least lubricated and most prone to wear out. Disassembly and inspection of many of these engines have led this writer to believe the front valve guide nearly always exhibits the greatest amount of wear of all the engine guides. Second in likelihood of wear are the remaining exhaust guides, while intake guides rarely if ever show wear. If intake guides do leak, they tend to draw oil into the guide, which tends to aid lubrication. No valve seals are used on flathead engines

MoPar engines use hardened valves and seats as standard equipment. In this area, these engines are truly overbuilt. When valves show wear, they are invariably exhaust valves. Experience has proven that worn exhaust valves are nearly always caused by worn valve guides. Exceptions to this rule can be a piece of carbon or other debris causing a valve to hang open and burn.

Lubrication Systems

Mopar flathead engines were manufactured at a time when the technology of engine oil was still primitive, by today’s standards. Much of the wear restorers encounter upon disassembly is the result of the poor state of available lubricants. The oil we buy and use today is light years ahead of that available fifty years ago.

Bypass oil filtration systems were never very helpful, but happened to be the only thing available in the forties and early fifties for these engines. The nature of bypass filtration is that likely ten percent or less of the total oil circulated by the oil pump ever gets to pass through the filter. The line that feeds these filters is the smallest diameter steel line used in automotive manufacturing. Even this meager amount of volume allowed to pass through the filter system is shut off during periods of low oil pressure, and only opened for circulation when oil pressure rises above a given pressure point. These bypass filters were optional, for many engines were produced without them.

Full-flow oil filter systems, by comparison, filter ALL oil that is picked up by the pump and circulated inside the engine. Several restorers have performed work-around adaptations for these engines to adapt full-flow filtration to them. This improvement, in this writer’s estimation, goes a long way toward extending engine life. Full-flow oil filtration coupled with modern high detergent oil technology, will allow these already-well-built engines to last much longer between overhauls.

Engine Blocks

Do not be fooled by the small (218/230) cubic displacement of these engines. They are heavy block castings that warm up slowly due to their large mass. The water jacket inside the block is only present in the top several inches of the casting, where the heat of combustion is greatest. On the passengers’ side is the valve chamber, and there is no coolant flow below the level of the water distribution tube, well above the camshaft level. On the driver’s side, the water jacket extends down to the block core plugs and thingy, but the flow is mainly limited to the upper section. The area on the thingy side is typically where sediment and dirt settle inside the block. I have seen these blocks filled with sediment above the tops of the core plugs at the rear. This of course must all be cleaned out as part of any overhaul. Remove all block core plugs and use whatever method you have at hand to make sure everything is clean and free of sediment and dirt.

It is logical to believe that these fifty-plus year old engines may have several hundred thousands of miles on them, in spite of what you want to believe. Logic further dictates that cylinder heads have been removed several times for valve and piston work during the life of the engine. While the head is off, it is a good thing to check the deck with a straight edge, both for warppage and for distortion. It is not likely that an engine has been overheated sufficiently to warp the entire block casting, but close inspection usually shows some heaving or mushrooming of the deck surfaces around each head bolt hole. I have been successful in removing these distortions with a sharp flat file. Just start at one end and swipe crossways over the deck area. This will reveal high spots around each head bolt hole. These can be filed down to a true flat area with a little diligence. The result is a more precise deck surface against which the head gasket can seat. Most folks know that heads can be safely milled sixty or seventy thousandths to improve compression ratios. Even if this is not important to you, a resurfacing of the head is recommended, just to be sure of a flat surface for the gasket. If you can afford it and your block is at the machine shop for cleaning anyhow, have them resurface the deck a few thousandths to get a true surface. The same advice would not hurt a bit for the manifold gasket surface on the block.

Crankcase Ventilation

Another element of engine technology that has gained vastly from modern engineering understanding is crankcase ventilation. Originally designed only to ventilate the crankcase of fumes and condensation, this system is forced into double duty when an engine begins to wear excessively, for now it also has to handle blow-by products of combustion that have escaped past worn pistons and rings..

Positive crankcase ventilation (PCV) systems were originally mandated with a view toward limiting crankcase emissions. A secondary benefit of the PCV system is its ability to remove much more of the condensation and moisture from the crankcase than was originally possible with the primitive road draft tube that was always open to the atmosphere. Yet another advantage of the PCV system is its ability to disperse any blow-by from the crankcase by returning it in the engine.

It is easy to modify these flathead six engines from the original road draft system to the newer, superior PCV system. This is true mainly due to Chrysler’s involvement in military vehicle production during WWII. Many of these military vehicles were equipped from the factory with engines designed to ford streams and run in semi-submerged conditions for short periods of time. One part of these engine sealing systems was the PCV system designed to keep water OUT of the crankcase.

A direct result of this fact is that most military vehicle parts suppliers are equipped to offer the PCV adapter necessary for this conversion. This writer found one at Vintage Power Wagons. The adapter is a round, cast metal piece that bolts to the rear of the block in the same spot as the original road draft tube. From this adapter, 3/8-inch tubing is routed forward and up to the intake manifold. A pipe plug in the center of the intake on the outboard side can be removed and this line connected to it as a vacuum source. In series in this line must be a PCV valve, of the type typically used on any engine of equivalent cubic inch displacement. Because of the closeness of this vacuum line to the hot exhaust manifold, this writer chose to use an all-brass PCV valve, available from the same military source. A PCV system on these engines, coupled with modern oil and a by-pass filter, offer a recipe for extended engine life.

Thermostats

It is impossible to operate an internal combustion engine without generating condensation in the crankcase. It is just a fact of life. If the moisture is removed, it presents no problem. If it is not removed, the result is an eventual buildup of sludge.

The only way by which the moisture of condensation can be removed from a crankcase is evaporation. This evaporation can only take place in the presence of heat and air movement. If the crankcase and engine block heat is not high enough for evaporation to occur, the condensation moisture will remain inside the block. Since this is water, which is heavier than oil, it will go to the bottom of the crankcase or valve chamber. It is for this reason that these are the areas where sludge is typically found in greatest quantity on tear-down. This writer has disassembled many of these engines were more than one pint of sludge was present in the valve chambers alone.

The best remedy for condensation removal is a high temperature thermostat. Vehicles built in the forties and fifties (and before) were designed to use alcohol based antifreeze. This required the use of low temp thermostats. Today we use glycol based antifreezes with much higher boiling points. Actually, the use of a 50/50 mixture of permanent antifreeze and water RAISES the boiling point of the coolant. All this is in aid of explaining why higher, rather than lower temperature thermostats are beneficial to longer engine life. The use of a 160 or 170 degree thermostat today with permanent antifreeze is an invitation for sludge to form in the crankcase. You are doing your engine no favor at all by keeping it running cool, in spite of how it may seem to your own sensitivities.

Not only do higher temp stats cause higher engine operating temperatures which aid in condensation removal, but they also help to raise the temperature more quickly, resulting in less cold engine operating time. Once stat temperature is reached, normal cooling will take place, but at a little higher temperature. Yet another reason why these flatheads need more heat than some engines is that they are heavy castings. A flathead six cylinder 218 cid engine weighs several hundred pounds more than a small block Chevy 350. This casting mass takes TIME to heat up and get up to operating temperature.

Many owners believe that when their dash gauge shows normal temperature, the engine is truly warmed up. Nothing could be further from the truth. Remember this one idea: an engine may warm up and the thermostat open to full circulation long before the block casting around the valve chambers has come up to full operating temperatures. It is this writer’s estimate that it takes nearly thirty minutes of engine operation for a typical flathead block to reach normal operating temperature in cool weather.

Please remember, I’m not talking about the thermostat or the top radiator tank, but the block casting, itself. This is where the condensation occurs and must evaporate from. In order to keep these block casting spots free of sludge, they must get up to full operating temperature. Proof that many of these engines have spent much of their lives running too cold is the sludge found inside the blocks. Granted, engine oils and filtration were of poor quality by comparison to today’s technology, but those engines that are run warmer are always cleaner. An example of this is the fact that larger truck engines are usually found to have less sludge than small trucks and automobiles. Check it out.

Consider a newly restored vehicle with a completely new and clean engine assembly. To keep this engine clean, it should not be started and driven short distances, again because the block will not have an opportunity to achieve operating temperatures. When I use my old stuff, I start it, let it run at idle for a while, then drive it, hopefully at least thirty minutes. I will jack up a car and push it in or of a stall to avoid starting a cold engine for only a few minutes, for this very reason.

It goes without saying that all this talk about getting engines up to temperature is doubly true for the exhaust systems. Exhausts live linger in an atmosphere where they warm up completely each time they are used. Why do you think tail pipes rot off three or four times before head pipes and mufflers? They are always cooler and warm up slower, since they are farther from the source of heat.

Cooling Systems

Cooling systems seem to be one of the more misunderstood components of older engines. In order to understand them, it is necessary to understand the combustion process. A typical gasoline engine running at 2000 rpm under no load will generate a certain amount of heat, but this will soon be realized and stabilized.

Add to this engine now an increased load on the crankshaft, and many things happen at once. First, in order to maintain rpm, the throttle plates must be opened further. This is done automatically if the engine is governed, or manually in an automotive application. The amount of fuel entering the engine increases, the result of which is an immediate increase in combustion chamber pressures and temperatures. It is this sort of use that cooling systems must handle in order to protect an engine. Normal driving under light load barely works the cooling system at all. It is at higher engine loads that the cooling system must be able to function well.

From the engine’s perspective and from a combustion standpoint, the hotter an engine temperature, the better and more efficiently the engine will. Fuel atomizes more freely and the combustion process thrives in an atmosphere of heat. This is difficult for many older vehicle owners to comprehend, yet it is fundamentally true . . . . . . Up TO THE POINT where the engine will begin to suffer metallurgical from the heat. Therefore, the job of the cooling system is to allow the engine to run as hot as safely possible in order to aid the combustion process, yet keep it cool enough to protect it.

Engines are designed to withstand lots of heat safely. Unfortunately, the margin for safety between “hot enough to run well” and “too hot for engine safety” is not a very wide one. When metal parts are heated, they expand. When they cool again, they contract. This cycle can happen over and over with complete safety, as long as the extremes of the heat range are not reached. If metal parts are heated so much that they do not contract to their normal tolerance after cool-down, the metal is said to have warped. This action is most often noticed on cylinder heads and manifold castings that have been subjected to hundreds of heat/cool cycles.. Typically, the remedy for a warped casting is resurfacing.

An example of this action is the typical small block Chevy cylinder head, where the valve arrangement is such that two exhaust valves sit adjacently in the middle of the cylinder head. This is nearly always the point of failure with these castings, for this is the hottest spot on the component.

How does this all relate to MoPar flatheads? The design of these engines is such that a water distribution tube is used in the cooling system to aid in dispersing coolant to the bottom of the exhaust valve seat castings. In this sense, these engines are truly overbuilt, for this is a feature not used by very many other manufacturers of the time. An analogy to this feature would be oil nozzles directed to piston crowns in modern diesel engines – a feature that goes far to extend engine life. Flathead radiators are also overbuilt from a size standpoint, and are truly impressive in their ability to transfer heat from the engine and transfer it to the air. When these engines are warmed up to 180 – 200 degrees F, they run happily all day, run more efficiently and stay cleaner. They live linger, as well.

Having said all this, the water distribution tube is a critical link in the cooling system. Never pull a water pump without at least pulling and checking the distribution tube. It goes without saying that no engine overhaul should ever be contemplated without inspection of this part as well. The tubes are reproduced by several vendors and are available.

Bottom Line

If you truly want to do the best you can for your MoPar flathead, here’s my recipe:

• Modern high detergent motor oil in a clean engine

• Full-flow oil filtration system in place of the part time bypass system

• PCV system instead of the primitive road draft tube

• High temperature (180 or higher) thermostat

• Good quality paper air filter instead of an oil bath system

Rear Main Bearing Seals

Engines built before 1951 used a rear main seal that incorporated a flat metal flange with three screw holes in it. These seals required removal of the flywheel to allow replacement of the top half. Later flathead engines used a different neoprene seal design that could be rolled into place in the top half by loosening the crankshaft, much as you would in replacing a top rear main bearing. The two types of seal are not compatible reciprocally, due to block casting differences.

Timing Chain/Gear Lubrication

Engines built before 1951 use a pressurized oil nozzle of about 1/16-inch diameter to lubricate the timing chain and components. This tube protrudes from the block above the center of the crankshaft gear and points downward, and has a small bracket attached by one screw to the front of the block. The oil is sourced from the front oil passage leading from the main galley on the left side of the block to the front camshaft bearing.

This system provides positive lubrication to timing components and is very nice . . . . . . as long as it stays clean and free from sludge. It was abandoned in later production in favor of an oil slinger disc placed behind the crankshaft timing gear that supposedly slung oil up and onto the chain. Since the slinger lives above the normal oil level in the oil pan, it can operate only when the engine is running. In this writer’s humble opinion, the earlier pressurized system was far superior, and was discontinued only because of the poor quality oil available at the time and the difficulty in getting the block hot enough for this oil component to get warm enough to keep sludge from forming. It would be interesting to compare timing chain wear between two otherwise identical engines, to observe which of the two systems really provides best lubrication and least wear.

Connecting Rods/Caps

Somewhere around 1951 again, a change was made in connecting rod and cap design on the 218/230 engines. Earlier engine design used a special very thin-wall lock washer that sat in a relief on the cap to retain the rod nut. Later engines dispensed with this relief area and used a flat boss on the cap and instead of the thin lock washer used a split lock nut with several small perforations in the top half. What is interesting is that both rod types carry the identical casting number.

The two rod cap types each require use of the correct fastener, and cannot be mixed or matched. If you have the earlier type rods, you must use the lock washers and nuts. This writer has been unsuccessful in finding a vendor source for these washers. They are quite easy to loose on disassembly, especially if you don’t know they are even there. When installed, they are not visible due to the recess in which they sit. And they are hard to find when they are dropped. Ask me how I know. It goes without saying that rod caps can never be interchanged on connecting rods.

Oil Pans – Oil Leaks

The front of the oil pan area on these engines presents a small challenge for first time restorers. There are several places from which oil can leak, all of which will show up at the front pan area. In order to understand the nature of the situation, it is necessary for the reader to have seen the individual parts.

The front of the oil pan has a wide cork gasket which rides against an aluminum saddle, designed just for this purpose. The aluminum saddle is held in place by two machine screws, and must be removed before access can be had to the front main bearing bolts, for they are partially covered by the saddle.

The engine timing cover gasket must seal the cover itself, the front of the block and this aluminum saddle on which rides the oil pan gasket. It is at the juncture of these three pieces of metal – block, timing cover and aluminum saddle, that oil leaks can easily arise if proper assembly is not observed. This might be a good place to mention that the timing cover has one bolt on the passenger’s side that enters the cover from the rear of the block flange, in direct opposition to all the other cover bolts.

In addition to this area of potential leakage is the front main oil seal that sits in the timing cover and rides on the crankshaft pulley. Always check the seal area on these pulleys for wear. It is not unusual to find a definite groove worn into the pulley seal area from seal lip and dirt wear at this point. A worn pulley will cause a new seal to leak. Speedy sleeves are available, as are “trick” seals that ride on a new and different spot on the pulley to avoid the worn groove spot.

This writer also likes to incorporate a good sized magnet inside the oil pan on reassembly for attracting any wear metal pieces that may get into the crankcase. Old flat speaker magnets are perfect for this purpose. Never throw one away. An ounce of prevention . . . . . .

Miscellany

Engine assembly involves using many bolts that thread into water jacket passages. This is true for head bolts, manifold bolts and a few of the upper timing cover bolts as well as the three water pump bolts. It is important that these bolt threads have some form of waterproof sealer used on them. Clean, tight threads can still leak fluid past them if not sealed. There are no shortcuts to cleanliness that work here. Never use or hang a dirty part on a rebuilt engine.

Engine reassembly is fairly critical work. It cannot he done in a less than clean environment. With all the engines I have ever overhauled, I spent about two hours of parts cleaning time for every half hour of assembly. Fasteners and related block thread holes must be completely clean. The only way this writer has been successful at this task is to use thread taps and dies on each individual part. I have cleaned head bolts on a wire wheel grinder to the point that they shined, yet when the threads were chased with a die, a pile of dirt and carbon showed up on the vise. Do not worry about removing metal with a tap or die. If you are using the correct size, the threads will not be damaged.

MoPar flathead engines were manufactured with very low compression ratios, even for their day. This engineering was based much on the octane levels of fuel available to the public. Flatheads respond very nicely to an increase in compression ratio. This can be accomplished quickly and cheaply by milling material from the bottom of the cylinder head. Doing this will also assure that the head surface is true and free from warpage, as well as offering an opportunity to increase compression and engine performance.

Unleaded fuel offers no problems to these engines, in this writer’s opinion. They certainly do NOT need high octane fuel. Using it in flathead engines will not be beneficial in any way, contrary to the opinions of many. Valves and seats are already of superior quality from the original manufacturer. Just make sure when you set initial engine timing that the engine does not ping or preignite under load.

On the subject of engine timing, here is one often ignored area of performance – the distributor. Distributors have two timing advance mechanisms incorporated in their design – vacuum and centrifugal. The vacuum advance is visible on the outside of the distributor and can easily be tested by mouth or vacuum pump. If it doesn’t leak it will be okay, as long as the distributor breaker plate moves freely inside the cap.

Centrifugal advance units are harder to see, for they are underneath the breaker plate that holds the contact points and condenser. These mechanisms are usually trouble free, but may wear over time. Short of removing the distributor and having it tested on a stand, the only way to test a centrifugal advance unit is with an advance-type timing light and a knowledgeable mechanic. Specs for both vacuum and centrifugal advance units are available with other tune-up data, and of course are a requirement before checking either advance unit. Suffice to say that lots of flatheads are weak in these areas. When one performs well, it is usually a sign that both systems are functioning correctly.

This still leaves the issue of initial timing, which refers to the relationship of the engine to the distributor, and is adjusted by turning the distributor in the block while the engine is running, with the use of a timing light. Power timing, advocated by a few, aids little with these engines, unless you are a performance buff. If such is the case, have at it . . . .
