An alternative to buying an entire assortment of snap ring pliers is to buy one set that has removable tips. Applying these cleaners before power washing or hand cleaning helps to loosen heavy greasy deposits from the case. Spring Compressors Turbo-Hydramatic 350s require a piston spring compressor inside the case. A torque wrench is necessary, as each fastener size has a torque value based on its diameter and hardness. Some snap ring pliers are also designed to be convertible.
Output Shaft Seals Transmission fluid stains are almost impossible to remove from non-sealed concrete and asphalt surfaces. High-pressure compressed air is also necessary to bench-test clutch packs and other components during the rebuilding process. However, neither should be used to tighten fasteners because most go into the aluminum case, which is soft enough that the threads may strip out if excessive torque is used. You must record your accurate measurements and carefully install these bushings to the same depth that they were originally at. They do not require compressed air and are much less likely to overtighten any fasteners. Many bushings are difficult to remove without splitting them first, especially if they are in blind holes.
Large flat-blade screwdrivers can be used to remove the snap rings in the transmission cases and also to reposition them. With the engine idling in park, vehicle supported safely, pull off the hose at rear of the modulator. Another method that can be used here is to blow compressed air into the oil-supply passage for the intermediate clutch pack. This bushing is difficult to remove by any other method. Along with a complete set of basic tools, such as ratchets, screwdrivers, and wrenches, transmission tools are essential for performing a wide range of automotive tasks, including installing tone rings and removing a rear clutch piston snap ring. But there is something about it that keeps away even the most skilled automotive technicians.
Even the low-decibel din of shop equipment, electric motors, gear and belt drives, air compressors, and the like, damage hearing with exposure over time. The factory machines a slight chamfer on the edge of each drum to help with seal installation. A standard 1-inch micrometer works equally as well for measuring frictions and steel plates, as well as the total thickness of a clutch pack. When they are ready for assembly, you must align the two halves or the pump will not fit back into the case. Friction and steel plates Raybestos 5.
All components seen here are the typical high wear and failure prone parts you must replace for a long lasting transmission. To help complete a mechanic's tool box the mechanic will need both types of wrenches, Allen wrenches, a ratchet and socket set and a high powered air ratchet wrench. Completely and correctly rebuilding an automatic transmission is not beyond the capabilities of the average automotive enthusiast. You can make a band from a large single hose clamp or by putting several large hose clamps together. Leave the pump bolts finger tight while tightening the band. This repair is stronger than the original material. Air Tools Air tools are helpful in transmission rebuilding.
Shown here is a homemade unit fabricated from square stock and angle iron. Bushing Removers and Installers Automatic transmissions have numerous bushings. Onegallon plastic ice cream buckets work well for this purpose, and their lids keep dirt and debris off the new parts. Tools of the Trade There are tools in the automatic transmission trade you need to be familiar with: slide hammers, snapring pliers, mallets, tiny screwdrivers, awls and picks, presses, punches, bushing drivers, slide calipers, seal installation tools, roll-pin removal tools, alignment pins made from old bolts , seal drivers and installers, Torx drivers, and more. Air leaks, when pressure is applied, tell you there are potential fluid leaks around servo and clutch-piston seals.
Automatic transmissions are precision components that call for a clean working environment with a place for everything. Read on for an overview of some of the tools that will help you to repair and replace your transmission system. This requires a press or spring compressor that holds the direct drum in position and allows a compressor to center over the spring cage to compress. During the rebuild, you may use compressed air to clean parts and dry them. Hearing protection is also a very good idea. A Hot Flush system left purges transmissions and coolers of stray particulates that can damage new transmissions.
They can be used to remove lip seals from apply pistons, steel check balls from the case, and to pull steel and friction plates out of the clutch drums. When cleaning parts, an injury can result easily and very painfully if high-detergent transmission fluid or a piece of debris is blown into your eyes. It takes some patience when using this method, but it is an effective substitute for making an alignment tool for the clutch pack. This ensures that the halves do not slip out of alignment. You can use a cleaned 1.
