Removing/Installing Limited Slip Differential

Removal/Installation

Case/Differential:

Legend 1:

Legend 2:

- Refer to images for instructions and legends.

NOTE: From the 1991 model on, the counter bearing on the lateral limited slip differential is adjustable.





1 Counter-bearing
2 Hex nut - Tightening torque: 85 Nm (63 ft lb) (seal with Loctite 222)
3 Sealing ring (omitted as of March 1991)





A = Installed position

NOTE: Before removing the limited-slip differential, always check the amount of wear at the plates. If plates are re-used after a period of operation, the position of the counter-bearing (No. 1) must not be altered. If repositioning or removal of the counter-bearing is unavoidable (for instance to rectify a leak), always measure the installed position of the counter-bearing before removing it, so that it can be installed again in the same position.

Installation

NOTE: If the sealing gaiter is leaking, always renew the slave cylinder.





1 Spacing plunger
2 Adjusting screw
2a Measuring groove on adjusting screw
3 Knurled nut
4 Counter-bearing
5 Hex nut
6 Sealing ring

- Adjust the counter-bearing (only necessary if the plates have been renewed).
- The basic locking moment and the final drive set must be adjusted.
- The flexible gaiter for the slave cylinder must be installed.
- Slacken the measuring cylinder adjusting screw as far as possible (to make it easier to install the measuring cylinder).
- Install the measuring cylinder (special tool 9514) on the transmission and tighten the knurled nut.
- Adjust to a dimension of 31 mm (in the lateral locking (QS) range) with the adjusting screw on the measuring cylinder.
^ LS = Front-rear differential lock measuring range
^ OS = Lateral differential lock measuring range
- Screw in the counter-bearing until there is no more end play at the measuring cylinder's spacing plunger.
