Pulling roller bearing out of clutch housing
–  When pulling out, compress circlip -arrow- for roller bearing using pliers -C-.
-A-Counter support, e.g. -Kukko 22/1-
-B-Internal puller 30…37 mm, e.g. -Kukko 21/5-
  A35-0017
Pressing roller bearing into clutch housing
–  Support clutch housing using tube -VW 415 A- (not visible in diagram) directly under bearing mounting.
–  When pressing in, compress circlip -arrow- for roller bearing using pliers -A-.
–  Remove the pliers before the roller bearing is in its final position. The circlip must engage in the groove in the clutch housing.
  A35-0018
Pressing off bearing mounting and grooved ball bearings
–  Slide locking collar for 1st and 2nd gear onto 2nd gear.
–  Slide in thrust plate -T10084 A- sideways until it contacts input shaft.
–  Insert centralising pins in thrust piece -T10081- into bores in input and output shafts.

Pressing off roller bearing inner race
–  Remove circlip.
–  Press off inner race of roller bearing together with the following components:
t  Thrust washer
t  4th speed selector gear with needle bearing
t  Locking collar/synchronising hub for 3rd and 4th gears
t  3rd speed selector gear.

Dismantling and assembling 3rd and 4th gear locking collar and synchronising hub
1 - Spring
2 - Locking collar
3 - Synchronising hub
4 - Locking piece
–  Push locking collar over synchronising hub.
The deeper recesses -arrow A- for the locking pieces in the synchronising hub must align with the recesses -arrow B- in the locking collar.
  A35-0023
Assembling 3rd and 4th gear locking collar/synchronising hub
l  Locking collar is pushed over synchronising hub.
–  Insert locking pieces in the deeper slots -arrows- and install springs off-set by 120°. Angled end of spring must locate in hollow locking piece.
  A35-0024
Installation position of 3rd and 4th gear locking collar/synchronising hub
The groove on the top -arrow- points towards 4th gear.
  A35-0025
Checking synchro-ring for wear
–  Press synchro-ring onto tapered seat on selector gear and measure gap “a” with a feeler gauge.

Determining thickness of circlip
–  Insert a 2.0 mm thick circlip -A- in groove of input shaft and press upwards -arrow-.
–  Measure gap between inner race -B- and fitted circlip -A- using feeler gauge -C-.
–  Remove circlip fitted for measurement.
–  Select circlip from table.
