Clutch A

NOTE: Component identifier numbers used in the following illustrations relate to specific steps in the procedures below.





Disassembly
1. Remove the circlip using suitable pliers.
2. Withdraw the turbine shaft towards the drive side.
3. Remove the circlip from the cylinder and withdraw the entire plate assembly, including the spring plate.
4. Press down the holder plate in a press with tool No. 87 91 535 and remove the circlip using pliers tool No. 87 90 180, or equivalents and a screwdriver.
5. Remove the holder plate and the two Belleville washers under it by tapping it lightly against the workbench.
6. Install a compressed air gun to one of the two fluid supply passages, cover the two open fluid supply passages and press out plunger A using the compressed air.





Assembly
1. Install new O-rings to the plunger and grease them using Vaseline.
2. Press plunger A into the cylinder. Then install the conical washer and then the Belleville washer with the domed side upwards. Alternatively, only a Belleville washer, see illustration.
3. Install an O-ring to the holder plate and grease it with Vaseline.
4. Install the stop washer and press it down using tool 87 91 535 in a press. The circlip can be installed by hand, but use pliers if necessary.
5. Install the entire plate assembly for clutch A. Start with the spring Plate, followed alternately by outer plates and friction plates. There should be five friction plates.
6. Install the final plate and secure using the circlip. Check and, if necessary, adjust the clearance in clutch A.





7. Check and adjust clearance in clutch A.
a. Install the circlip, selected thickness = 1.0 mm (0.39 inch)
b. Install fixture tool No. 87 91 808 and dial gauge tool No. 78 40 622, or equivalents.
c. Place the gauge tip tool No. 87 91 857, or equivalent, against the final plate and set the dial gauge to "0".
d. Lift the entire plate assembly and read clearance on the dial gauge. Clearance should be:
- with 5 plate pairs = 1.8-2.0 mm (0.07-0.08 inch)
- with 6 plate pairs = 2.3-2.5 mm (0.08-0.10 inch)
e. If the reading deviates from the specified value, a thicker or thinner circlip should be used.

NOTE:
^ If new plates have been installed, they should be removed after this check and be placed in automatic transmission fluid for a short time.
^ If plates are dry, they may burn.

8. Install both seals to the turbine shaft and attach.
9. Install the O-ring and grease it lightly with Vaseline.
10. Press the turbine shaft into cylinder A and install the circlip using pliers.

NOTE: Pull the turbine shaft to its stop position using the circlip. (Axial clearance may be incorrect).
