From gearbox date 20 03 6, modified in area above deep groove ball bearing To accommodate the washer → Item, the area above the deep groove ball bearing → Item has been machined deeper.

Area above deep groove ball bearing	Dimension “a”
From gearbox date 20 03 6	10.7 mm
Through gearbox date 19 03 6	10 mm

From gearbox date 20 03 6, modified bearing seat for deep groove ball bearing The bearing seat for the deep groove ball bearing → Item has been machined slightly deeper for the washer → Item-arrow-.

Pulling off deep groove ball bearing –  First remove retaining ring from input shaft. –  Before setting up pulling device, set thrust piece -VW 431- and thrust plate -40-105- on input shaft. –  Apply splitter -B- to peripheral groove for retaining ring in bearing. A -  Puller, e.g. -Kukko 18/1- B -  Splitter, 12...75 mm, e.g. -Kukko 17/1-

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

Pressing on 5th gear wheel Groove -arrow- in wheel must face upwards.

Pressing on deep groove ball bearing Groove for retaining ring faces upwards -arrow A- and shoulder -arrow B- must face 5th gear wheel. –  Determine and install retaining ring → Fig..

Determining thickness of retaining ring –  Insert a 1.86 mm thick retaining ring -A- in groove of input shaft and press upwards. –  Measure distance between deep groove ball bearing -B- and installed retaining ring -A- using feeler gauge -C-. –  Remove retaining ring used for measuring purposes. –  Determine retaining ring from table.   Note! Allocate retaining rings using → Electronic parts catalogue (ETKA). The following retaining rings are available:

Measured value (mm)	Retaining ring thickness (mm)	Axial play (mm)
0.01 … 0.05	1.86	0.01 … 0.05
0.05 … 0.07	1.89	0.01 … 0.05
0.07 … 0.10	1.92	0.01 … 0.05
0.10 … 0.13	1.95	0.01 … 0.05
0.13 … 0.16	1.98	0.01 … 0.05

Pulling cylinder roller bearing out of clutch housing –  When pulling out, squeeze together retaining ring -arrow- of cylindrical roller bearing, using pliers -C-. A -  Counter support, e.g. -Kukko 22/2- B -  Internal puller, 30...37 mm, e.g. -Kukko 21/5-

Pressing cylindrical roller bearing into clutch housing –  When pressing in, squeeze together retaining ring -arrow- of cylinder roller bearing, using pliers -A-. –  Remove pliers before cylindrical roller bearing is in installation position. Retaining ring must engage in groove of clutch housing.
