Removing securing bolt -arrow- for needle bearing –  Unscrew securing bolt -arrow-.   Note Bolt is not fitted on all versions.

Driving out needle bearing

Installation position of needle bearing Distance -a- from lower edge of straight edge to upper edge of needle bearing = 39.5 mm   Note Measure distance from top edge of straight-edge and subtract the width of the straight-edge from the measured distance.

Pressing in needle bearing

Installing securing bolt -arrow- for needle bearing –  If fitted, screw in securing bolt and tighten to 25 Nm.

Knocking oil feed sleeve into input shaft

Item	Oil feed sleeve dia.	Fitting tool
A	14 mm	Drift -VW 222 A-
B	16 mm	Drift -30 - 24-

t  Installation position: Flanged edge on oil feed sleeve faces towards fitting tool. t  Installation depth: 3.5 mm below end of shaft

Pulling out roller bearing A -  Internal puller 23.5...30 mm, e.g. -Kukko 21/4- –  Before fitting internal puller the plastic bush inside the roller bearing must be destroyed.

Installation position of roller bearing t  Dimension -a- = 216 mm

Driving in roller bearing

Pressing off 5th gear wheel –  Remove circlip before pressing off. A -  Splitter 22...115 mm, e.g. -Kukko 17/2-

Pressing off 3rd and 4th gear synchronising hub –  Remove circlip before pressing off. –  Place splitter -A- below 3rd speed selector gear. Press off synchronising hub with 3rd speed selector gear. A -  Splitter 22...115 mm, e.g. -Kukko 17/2-

Inserting spring in selector gear The bent end of the spring -arrow- must be hooked into the hole in the selector gear.

Checking synchro-ring for wear –  Press synchro-ring -E- into locking collar and measure gap -a- at positions -A-, -B- and -C- using depth gauge -D-. –  Add the measured values and divide by 3. The determined value should not exceed 0.45 mm.

Installation position of circlips t  The circlips -1- and -2- secure the input shaft ball bearing. Determining thickness → Chapter. t  The circlip -3- secures the 3rd and 4th gear synchronising hub. Thickness: 2.00 mm. Identification: brown colour. t  The circlip -4- secures the 3rd and 4th gear synchronising hub. Determining thickness → . Identification: blue colour. t  The circlip -5- secures the 5th gear wheel. Determining thickness → .

Determining thickness of circlip –  Determine the thickest circlip that will just fit and install it. –  Determine circlip as accurately as possible from table. For part numbers refer to → Electronic parts catalogue. The following circlips are available for 3rd and 4th gear synchronising hub

Circlip thickness (mm)
1.90	1.96	2.02
1.93	1.99	2.05

The following circlips are available for 5th gear wheel

Circlip thickness (mm)
1.90	1.96	2.02
1.93	1.99

Pressing on synchronising hub for 3rd and 4th gear t  Installation position: High inside collar faces towards 3rd gear.

Installation position of locking collar Different types of locking collar are installed: version -A- with chamfered surface -arrow 1- or version -B- with large shoulder -arrow 3-. t  Installation position: Chamfered surface -arrow 1- faces towards 4th gear. Small shoulder -arrow 2- faces towards 3rd gear. Large shoulder -arrow 3- faces towards 4th gear.

Pressing on 5th gear wheel   WARNING Wear protective gloves. –  Heat 5th gear wheel to approx. 100 °C before pressing on. t  Installation position: Higher shoulder faces towards reverse gear
