Pulling dished washer -A- out of output shaft

Pressing dished washer into output shaft onto stop

Pulling out tapered roller bearing outer race A -  Counter-support -Kukko 22/2- B -  Internal puller 56 ... 70 mm -Kukko 21/8-

Pressing tapered roller bearing outer race into clutch housing –  Place drift sleeve -40-20- directly under bearing mounting to support clutch housing.

Pulling off tapered roller bearing inner race –  Before fitting puller, position press tool -VW 431- in output shaft and set thrust plate -40-105- on it.

Pulling off 3rd and 4th gear synchronising hub/locking collar with 4th speed selector gear –  First remove circlip. A -  Puller -Kukko 18/2- B -  Splitter 22 ... 115 mm -Kukko 17/2-
