Pulling off grooved ball bearing
–  First remove circlip from input shaft.
–  Before setting up puller, position thrust piece -VW 431- and thrust plate -40-105- on input shaft.
–  Apply splitter -B- at circular slot for circlip in bearing.
A - Puller, e.g. -Kukko 18/1-
B - Splitter 12...75 mm, e.g. -Kukko 17/1-
  N35-10001
Pressing off 5th gear wheel
A - Splitter 22...115 mm, e.g. -Kukko 17/2-
  N35-10002
Pressing on 5th gear wheel
Slot -arrow- on gear wheel must face upwards.
  N35-10003
Installation position of grooved ball bearing
Slot for circlip faces upwards -arrow A- and shoulder -arrow B- must face towards 5th gear wheel.
  N35-10004
Pressing on grooved ball bearing
Grooved ball bearing with rubber ring -arrow-
Shoulder -A- faces towards press tool -VW 412-.
–  Determine thickness of circlip for grooved ball bearing on input shaft (⇒ next illustration) and fit circlip.
  N35-10237
Determining thickness of circlip for grooved ball bearing on input shaft
–  Install a 1.86 mm thick circlip -A- in slot on input shaft and press circlip upwards.
–  Measure gap between grooved ball bearing -B- and fitted circlip -A- using feeler gauge -C-.
–  Remove circlip fitted for measurement.
–  Select circlip from table.
  Note
Select circlips from → Electronic parts catalogue.
The following circlips are available:
  N35-10005
Measured value (mm)Circlip thickness (mm)Axial clearance (mm)
0.01 … 0.051.860.01 … 0.05
0.05 … 0.071.890.01 … 0.05
0.07 … 0.101.920.01 … 0.05
0.10 … 0.131.950.01 … 0.05
0.13 … 0.161.980.01 … 0.05

   
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 22/2-
B - Internal puller 30 ... 37 mm, e.g. -Kukko 21/5-
  N35-10006
Pressing roller bearing into clutch housing
–  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.
