Case: Service and Repair

Removing and installing gasket for spur-gear cover

Removal
1. Remove silencers.





2. Unscrew silencer holder from transmission.





3. Clamp shut flow-side coolant hose with special tool 3094.





4. Unscrew flow-side coolant hose at port plate.
5. Place oil collection pan under the transmission.
6. Unscrew screws of spur-gear cover.

Note Slowly and carefully remove cover from transmission housing. Otherwise the spur gears may fall out of the transmission housing. Spur gears that have fallen onto the floor must not be reinstalled. The gears must be exchanged in this event.

7. Remove cover and secure spur gears against falling out.

Note If the spur gears have nonetheless been removed, when they are being replaced the markings must face outwards (away from transmission).

Installing
1. Ensure faultless seating of the dowel sleeve.
2. Screw two centering pins (special tool 9321) into the transmission housing, put new gasket on and fit cover.
3. Tighten screws in two steps.
1st step:
Tighten screws 1, 2 and 3 by hand. Ensure that the gap between cover and transmission housing is equally reduced all round.





2nd step:
Tighten screws 1 ... 14 in the stated sequence to 23 Nm (17 ft. lbs.).
4. Check and top up ATF level.
