Governor - Once you remove the cover plate you have to remove the right (output gear). Beneath it is a bearing race that needs to be pulled using an internal bearing puller. If you don't have one, you can use a two jaw puller with the ears reversed and use the pinon shaft as a place for the puller screw. If this sounds confusing, don't attempt the job! If you do get the bearing race out, extracting the governor as an assembly is the easy part. I would not recommend taking the governor apart unless you are confident of your mechanical ability and/or have good reference diagrams. It is not necessary to disassemble to replace the seals. There are two rubber and one steel seal. BE VERY CAREFUL not to damage any of them when installing. After putting the rubber seals on, let them relax in their grooves in the governor body for at least 1/2 hour. It is tricky to reinstall the assembly without damaging the seals. Use a SMALL amount of Vasoline and wiggle the assembly back and forth as you are seating it. STOP if any noticable resistance is felt. Once the governor is reseated, use a soft faced (preferably dead blow) hammer to re seat the bearing race. Do no forget to put the bearing shim in before reinstalling the gear/bearing assembly.
Accumulator spring - If you have a turbo, you must have new o-rings to install the turbo assist pipe. Do not start the job without them. Remove only the LARGE TORX HEAD screws around the outside to free the valve body - leave the smaller head ones alone. You can pry off the turbo assist tube, if you have one, but DO NOT BEND IT! Try to ease it straight up and out.
Once the valve body is in your hands, turn it over and you will see the accumulator body. There are two chambers. The one on the right as you look at the cover plate with the main valve body down is the A accumulator - the one that the spring usually needs replacing. Remove three screws (top, bottom, and right side) and loosen the fourth (left side). Rotate the cover away from the right side chamber. A small piston, a large piston, and the spring should come out. Hold them with your finger to prevent them from springing out onto the ground. Replace the spring and push the large piston with the small piston inside back into the chamber. BE VERY CAREFULL to push it square into the chamber recess. The tolerances are very tight and if it is cocked to the side, it will jam and be very difficult to extract and reseat.
After you've buttoned up the chamber, the valve body must be reinsatlled with the gear selector in the "1" position, and the selector rod in the A accumlator pushed all the way in.
The turbo assist pipe must be reinstalled with new o-rings. They cannot be damaged in the installation or the valve timing will be compromised and the transmission trashed. There is a special tool for this installation, but I've never used it. I use a soft-faced hammer and a lot of gentle tapping between the two ends of the tube.
This covers some of the high points. If you attempt this and get into trouble, either post or send me an e-mail directly. I'll even talk with you by phone, if necessary.
Good luck,
SteveB
