Although you may want to rebuild a transmission not outlined in this book, you must realize that the cost of certain specialty tools required for a one-time job may not be justified. Please take the time to read all of the build-ups. Some of the tips and techniques used on one transmission may be used on another as well, or on one not covered in this book. Investing in factory shop manuals is a great ideaIt’s important to comprehend why the specialty tools are needed and what their function is. Working on a transmission you have never worked on before without any form of reference is a recipe for disaster. You may find that a required tool’s function may be duplicated by another means that you have at your disposal. I remember a Doug Nash overdrive having needed a special spring compressor and retaining-bolt kit. A shop press and three standard 8-mm bolts served the same function. You can copy and paste this link to share: It is best to ask what components come with the kit before making a purchase.http://eguiders.com/uploads/crosley-cr66-manual.xml
(See “Choosing a Premium Rebuild Kit” on page 32.) Better companies offer support. These kits include all wearable parts, such as bearings, synchro rings, thrust washers, needle bearings, gaskets, and seals. High-grade kits have OEM bearings and gaskets.Tools that have a lifetime warranty form a basic foundation and are a wise investment. They are great for gear work and prove useful for other projects as well. A few different-size bearing clamps, old transmission cases, piston wrist pins, aluminum round stock, and bearing races are great additions to your collection of press tools. I’ve purchased pliers at swap meets at rock-bottom prices. Buy up cheap retaining-ring pliers so that you can grind them if needed for specialty work. Old driveshaft yokes help you align tailhousings, and make sure the rear bushings are installed correctly. These also help you spin a transmission. Pry bar sets and screwdrivers, which you don’t mind using for anything but screws, are ideal for this work. Two-jaw or three-jaw pullers are nice, but I rarely use them. Propane torches for heating parts help install slip-on components, such as steel speedo gears that could get ruined by pressing or hammering them in place. Telescopic magnets are great for removing detent balls. Cheap dental-tool kits are great for removing O-rings and retrieving detent springs. I prefer nonserrated steak knives for removing gaskets rather than special gasket “scrapers.” Copper scouring pads are great for removing silicone sealant without marring aluminum surfaces. A big mistake is to use an air-powered rotary scouring pad to remove gaskets. This ruins the precision flat surface of the case and will lead to leaks. Reinforced wheels do not shatter and are much safer to use. I save all the discs that wear to smaller diameters for work in tight places. It also creates a larger steel surface area and tighter press fit, and it prevents leaks.http://tibbelit.se/userfiles/crosley-cr49-tw-manual(1).xml
For performance applications, rebushing both front and rear bores and moving the countergear up a few thousands of an inch helps reduce gear deflection. Personally, I’ve never used a holding fixture because setting up a transmission fixture is a time-consuming process. By following the techniques detailed in this book, a fixture simply isn’t required. It is easier just to send all of your parts to a production transmission shop and pay to have them pressure cleaned. Instead, I use electric impact guns. I hate the noise of compressors, and I don’t like blowing off parts because it creates more airborne contaminants. In addition, a small can of compressed air typically used for cleaning computers is usually adequate for the one-time job. A Dremel rotary tool with cut-off wheel is ideal for cleaning up gears. Bench grinders, drill presses, and a 4-inch disc grinder should be acquired for more serious work, such as slick-shifting gears or clearancing gears by cutting them back a bit. I’ve seen people run over objects, drop transmissions, and get into accidents. This leads to cracks, holes, and stripped threads. Welding broken mounting ears, caused by people pulling a transmission into the engine with bolts, is a common job, which should be done by a professional. You can warp a transmission case easily by using too much heat. Epoxies, such as J-B Weld, are great for fixing small cracks or porosity problems. Drilling and tapping out a small hole and then plugging it with a bolt is also an alternative to welding. Alloy main cases tend to stretch when a gearset explodes. Muncie and T10 transmissions have a tendency to leak from the front countershaft bore. Gears with missing teeth do not work. Since the gears in most manualshift transmissions are in constant mesh, if the teeth are broken on one gear, usually the matching gear exhibits some form of damage or stress caused by the upper gear slamming against it.
Often, people ask to purchase a new input shaft because the old one is missing three teeth. I ask them if they want to purchase a new matching countergear, and the response is usually “no,” because that gear is not missing any teeth. These people haven’t noticed the bent, cracked, or deformed teeth. As a rule, if one gear has broken teeth, always change the matching gear, too. When transmissions are run low on oil, gears can become blue or black in color. Usually the front gears starve of oil because oil moves to the back of the transmission when a car accelerates. Gears appear scuffed looking or gouged out in the center of the tooth. Chipped teeth are another story. Sliding gears that are non-synchronized, such as most reverse gears, also have chips. Some gears are simply chipped by poor assembly or handling techniques. It’s quite common for many new gears in boxes to have their share of dings and chips. Any transmissions I build also have the gears completely deburred. You can deburr most chipped gears just as long as the chipped section is no longer than one-quarter the length of the gear tooth and never extends into the root or center section of the gear tooth. Anti-rattle or anti-backlash plates are quite common in Muncie, Chrysler, and Saginaw transmissions. These spring-loaded plates are offset in relationship to the actual tooth profile. I cut these plates off because they can loosen up in a performance application. Using an impact gun is a sure way to either strip or snap the bolt. If a bolt seems hard to remove, try heating it first with a propane torch and strike it with a hammer. You want to hit the bolt flat on the head. The idea is to stretch the threads enough to loosen the bolt. Hex-socket pipe plugs easily strip. To remove really difficult bolts, heat and strike them, and then use a hammer to drive a Torx bit into the hex bore.
Slamming the Torx bit into the plug deforms the threads and produces a stronger contact pattern to make a stripped hex plug removable. In comparison, the new gear on the right shows how much material is actually missing from the gear on the left. The gear is still usable because both chipped ends overhang each other when engaged. This damage is always evident in gears that are unsynchronized and the overhang design is built into them. Inserts designed to repair threads, such as those made by Heli-Coil, have special taps and drill sizes. Only use the recommended drill and tap. Once it’s seated, the drive tang is snapped off. Tool supply companies and most auto parts stores usually have these readily available. You can use needle-nose pliers to grasp the tang and pull out the insert if your installation doesn’t work. Use a sharp centering punch in the middle of the bolt. The centering punch helps you start a drill. Drill with a small bit first and work up to the size of the bore so that you can install a threaded insert. When you have stripped threads, the wrong thing to do is rethread to a larger size. That is unprofessional. Threaded inserts from Heli-Coil make it possible to restore damaged threads to the correct size. The hole is tapped using a special tap that allows a threaded insert to be screwed into the bore. Once the insert is installed, the drive tang is broken off and the thread is restored. That is to only press and support the part against the area that is holding the press fit. For example, if a bearing is held in a housing by the outer race, press against that outer race. If the bearing is held on by the inner race, press or support against that inner race. If you support against the inner race and press against the outer race, you will deform the raceways, and basically damage the part. I cut apart older bearings and use the old races as support surfaces. I’ve purchased cheap socket sets and use the sockets as press tools as well.
However, never hammer on hardened parts. Be sure to use plenty of grease. The thought of loading more than 100 bearings in a gear can be intimidating. Oddly, most factory shop manuals advocate the use of “dummy shafts,” to load needles. I always say, “Dummy shafts are for dummies.” The problem with the dummy shaft is that you don’t see the needles or the position of the needles in the gear. You can’t see if you’ve put in the proper number of needles. When removing the dummy shaft and sliding in the real shaft in place, sometimes the needles can drop, which means starting over again. I use grease to pack the needles in place. You can use wheelbearing grease if the transmission is using conventional 75W-90 gear lubes. There are new assembly lubes, such as Trans Gel and Trans Goo. These assembly gels break down faster for both gear lube and automatic transmission fluid applications. They also seem to retain viscosity better in colder or warmer climates. If you’re working in a 96-degree shop in Florida, wheelbearing grease will not hold as well as an assembly gel. Don’t assume that a new ring is okay. I’ve seen many rings with defective machining or warping—you can warp a new ring by simply dropping it on the floor. A good ring should not wobble on the gear cone. It should fit firmly and lock to the gear while applying pressure to the ring as you rotate the gear. Make sure the ring is not sitting too high or too low. The average ring gap is 0.030 to 0.060 inch. A low-fitting ring makes for poor lock up and displaced strut keys. A high-fitting ring can cause binding. A worn gear cone that shows defined ridges prevents a ring from properly grabbing the gear. Sometimes a ring may lock well on one gear but not another. You can also use lapping compound, which is basically an abrasive paste to fit a ring to a gear. Once rings are fitted, the “set” is put aside until the build begins. Always fit rings, and never just place new rings on gears.
Once the teeth lose their point definition, they can ruin synchro rings and gears if not replaced because the teeth do not effectively mesh. However, if you look at the backside of the ring it sits too low and hits the gear. Therefore, this ring needs to be replaced. As the ring moves away from the strut key, the additional gap allows the strut keys to pop out and further damage the ring. You can see how slipping struts have damaged the key slot. Installing it in the 1-2 position will cause the edge to hit the lower counter gear. Notice that this edge is square. It’s important to recognize these subtle differences. The back taper or “torque-locking” design forces the gear’s engagement teeth to ramp toward the center, so it doesn’t fall out of gear. It should be used if the matching gears are in pristine condition. If the transmission tends to fall out of gear, the torquelocking sliders are better suited. If the keys show significant wear, they should be replaced. This key has been worn flat and definitely needs to be replaced. Some sliders have notches on all the splines; others have them in just in three places. It’s a good idea to use a felttip marker to indicate where the notches are. If the notches are not lined up correctly with the synchro strut key slots in the hub, the synchro will not work. Otherwise, it is alongside it. Insert the spring in a clockwise direction. When assembled, the springs will be opposite of one another and create a nice balance. I usually grind the spring tangs, so they don’t hit the inside wall of the hub. This helps to provide a clean, positive shift. There is no need to count. If you can fit one more needle, then you need that extra needle. Once I have all of my needles loaded, I take the countershaft I’m going to use and push it through the gear. I hold a thrust washer on the opposite end of the gear to keep all the needles from getting pushed out, and then I push the shaft through.
This adds some extra packing and squeezes out extra grease. I rotate the shaft in the gear because this allows me to check for binding and smooth rotation. Next, I then remove the shaft, which allows me to inspect the needles and check for complete rows, good alignment, and proper spacing. A dummy shaft cannot be used for any of these checks because the gear has been installed in the case after the shaft is removed. Rather than repeat these steps with each build, they are shown here only. Common causes for falling out of gear are worn engagement teeth on the slider and gear combined with a worn shift-fork groove and worn shift fork. Strut keys or shift dogs always give people assembly problems because they are spring loaded. Rather than assemble in this order: springs, keys, and slider, which is how most shop manuals tell you how to do it, simply place the slider on the hub first, then the keys and then the springs. Its best to use a press, but a punch will work if the fit is a slip or snug fit. First, verify that the edge of the ring fits the groove before installing it. Then use a micrometer to measure the width of the groove and thickness of the ring. Dialing-in the correct endplay is a matter of subtracting the width of the groove from the thickness of the ring. New designs always use them. This bearing had more than 100,000 miles and when I pulled the seals the bearing still looked pretty good. Most manufacturers today are using bearings made in the United States or Japan. If you need to replace the bearing, always use the OEM replacement bearing. Sometimes getting a bearing from a bearing supply house is not really a good idea because automotive- grade bearings require different fits and tapers. If you look carefully you can see how one side of the bearing has more wear than the other due to the nature of thrust loads from the helical-cut gears. This is something you must detect. The new bearing on the left has a slight chamfer to the inside diameter (ID).
The ID of the older inner raceway has a very square cut bore with no chamfer. The bore with no chamfer is a better thrust surface and will support a snap ring better. Better designs use a spacer in front of the raceway to maximize snap-ring holding capacity. They offer the rebuilder a simple way to perform quality checks. If you have more than one person working in a shop, it is a good idea to have your subassemblies inspected by someone else and vise-versa. Sometimes another set of eyes is all that is needed to prevent a potential disaster. The majority of people cannot distinguish between bearing noise and gear noise. Once bearings develop imperfections in the raceways and balls, these imperfections generate noise and vibration. Dust and debris in a bearing can cause noise when spinning it by hand, especially after cleaning a bearing in solvent that has debris in it. Try to get a light into the bearing to inspect the raceways for pits or craters. These usually appear as dark pits. A bad bearing produces sort of a growling, erratic noise because the components of the bearing never hit the exact same spot by the next revolution. However, gear noise is never erratic; it’s consistent. A broken tooth may translate into a knocking noise that gets faster as the RPM goes up. A whine or hum may change pitch with engine RPM, suggesting worn or mismatched gears. This can cause the noise of bad gears or bearings to diminish when in fourth gear. Bearings are relatively cheap. There is no point in reusing 40-year-old bearings when the new bearings of today exhibit better quality standards. Sometimes transmissions have selective snap rings to set endplay. Often the tightest fitting ring works, since gear clearances for oil are usually built into the design. Some early T10 4-speeds actually lock up with a snap ring that is too thick. If I can find an equivalent bearing with seals for an application, I will use it.
Dirt is the main cause of bearing failure; seals keep the dirt out. Oil actually still gets past the seals and keeps it lubricated. These are currently used in a great many of OEM applications. I coat gasket surfaces with this sealant or use it in applications that do not require gaskets. It makes for easy removal of the gasket and cleanup. Grease the internal lip of the seal and spring. Also coat the outer shell of the seal with sealant, which prevents oil from leaking around the seal due to surface imperfections. Try to use original-equipment gaskets when possible. There are several companies that now reproduce gaskets using the same compounds the factory did years ago. I always coat both gasket surfaces with either RTV Silicone or anaerobic sealant. I prefer the anaerobic because it sets on contact and cures within 20 minutes. This is great if you need to get something sealed up quickly and back in the car. Silicone sealants don’t cure that fast. If a transmission requires a gasket, use one. Using gasket eliminators may be great for an oil pan or valve cover, but sometimes the gaskets in manual transmissions actually set the spacing of the gears as well as endplay. Certain front-bearing retainers crack when using sealant only, because the gasket fills the gap between the two parts. Without the gasket, you might bend the retainer around the bearing and crack it as you tighten the bolts. A circular spring surrounds the inside diameter of the seal to maintain its shape as well as contact with the shaft. Before installing any lip seal, grease the seal. Applying a liberal coating of grease to the seal aids in initial lubrication of the seal as well as using the grease to hold the spring in place. Certain case castings have bolt holes that break into the inside. Most front bearing retainers have bolts that go right into the case. Oil can leak past the threads, so it is important to use some sort of sealant in these areas.

Additional troubleshooting resources. Before you get started there are some critical points to every new conversion that often get overlooked. Here at Bowler Performance we see and hear a lot of horror stories of installs gone bad due to lack of information provided, incorrect components received, or just a basic misunderstanding of how the parts are designed to work. So we’ve put together this fitment guide for you. Any time that you are bringing together parts from various manufacturers there is the potential for something to not fit quite as it was intended to. There are certain inspections and steps you will want to take before installing a new or different transmission in your car or truck that will assure a “one-time” installation.
Doing these steps only takes a few minutes and will save you headaches and head scratchin’ down the road. If you are still in the planning stages of your build and don’t yet have a transmission package, these are also important aspects to take into consideration with your purchase. Do not get trapped into believing that just because it was included in a quote or kit that it is the correct part for you. After all, this is your car, time, and money being invested. On the flip side of that, help your supplier out by being able to provide as much information about your engine and car as possible. If you do not know your engine specs (horsepower, torque, balance, crank bolt pattern, etc.) you leave yourself wide open to guessing what is correct. You never want to guess at what may be the right parts unless you like to spend extra time and money fixing mistakes. This is especially critical when you have a unique or rarely used engine that may be tough to find parts for. In some applications a bearing may stick out and cause interference with either the clutch disk or the splines on the input shaft. Your retailer may not have this information so some homework may be required on your part to make sure you’ll have enough room if you’re trying to run a bearing. This check can be preliminarily checked with the bearing or bushing not installed in the crank but MUST be verified after it is installed in the crank because the inside diameter will shrink. Ask your engine builder if you’re not sure. Aftermarket engine stroker kits typically follow existing motor balancing, but not always. The stroker kit manufacturer will have this information for you. This check is especially important for the Ford engine owners. Ford used 3 different engine balances over the years, so if you aren’t 100% sure what you have please take the time to find out. All of these checks will require a dial indicator and a magnetic base.
We have an additional guide on performing all of the alignment checks here since there is quite a bit of information on that topic alone. This is a critical step to perform regardless of which transmission is being installed. Too many times we’ve repaired a nearly new transmission only because this step was overlooked as not being that important. Never modify the mounting holes in the flywheel, never drill new mounting holes in the pressure plate or flywheel, and ALWAYS use the correct fasteners. There will either be locating pins and non-stepped bolts OR step-bolts and no locating pins. If you install a pressure plate that does not use pins and install non-stepped bolts you will get a vibration. Also, clutch pressure plates are balanced independently of any other assembly. Never balance an engine with the pressure plate installed. You can check the balance with the pressure plate installed but do not re-balance the pressure plate. And never check this with the disk installed since the disk cannot be perfectly centered. The top-hat side of the disk goes towards the transmission. There may also be a sticker on the clutch disk indicating which side goes which way. Verify the spline of the disk matches the spline of the input shaft of the transmission. Verify the clutch disk fits within the pressure plate opening and the edge of the disk comes to or very near the outside edge of the pressure plate surface. Too small of a disk will not be as effective. Additionally, set the disk in the opening of the flywheel and check for the same clearances. Make sure the disk does not come in contact with the flywheel bolts. The flywheel must be installed on the engine to do this check. The wrong size tool may not center your disk correctly making transmission installation difficult. Tighten down the pressure plate bolts evenly. Not doing this could temporarily warp the pressure plate and bind the alignment tool throwing off the disk center as you finish tightening down the bolts.
The alignment tool should slide in and out easily if the alignment of the disk is correct. We also have a guide dedicated to the Tilton hydraulic bearing set up for additional information. We’ve seen engine blocks, bellhousings, and transmission cases damaged from trying to use the bolts to draw the parts together. Not sealing the threads will result in oil getting on the disk surface. Lightly grease a pilot bearing, DO NOT grease a pilot bushing. Bottom line is you have a misalignment, interference, or clutch release issue. Things that can cause an energized input shaft are: Too much of this spring can cause drag when clutch is released, tasking the synchronizers in the transmission to work extra hard and cause premature wear. The Marcel is what allows the disk to align itself between the flywheel and pressure plate and eliminate that chatter during a slow clutch release. On the flip side, not having any Marcel will cause jerking and chatter. It’s such a small thing that plays a huge role in how a vehicle performs. We want to stress the importance of these procedures as a way to eliminate as many problems as possible. There is a lot of excitement when installing new parts that will quickly fade away when something isn’t fitting together correctly.
