Pulling tapered roller bearing outer race out of gearbox housing A -  Counter support, e.g. -Kukko 22/2- B -  Internal puller 46 ... 58 mm, e.g. -Kukko 21/7-

Pressing tapered roller bearing outer race into gearbox housing –  Support gearbox housing with thrust piece -2050- directly below bearing support.

Pulling off tapered roller bearing inner race A -  Vice with protective jaw covers –  First remove retaining ring. –  Before setting up pulling device, set extension -3161- and thrust plate -40-105- on input shaft.

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

Pressing off gear wheel for 3rd, 4th and 6th gears

Pressing off tapered roller bearing inner race A -  Splitter, 22 ... 115 mm, e.g. -Kukko 17/2-

Pressing on gear wheel for 3rd, 4th and 6th gears –  Heat gear wheel to approx. 100° C –  Press on gear wheel quickly so that the heat is not immediately transferred to input shaft.

Pressing on 5th gear wheel

Pressing on tapered roller bearing inner race –  Determine and install retaining ring → Fig..

Determining thickness of retaining ring –  Determine thickest retaining ring which will still fit and install it. –  Determine retaining ring from table. Part numbers → Electronic parts catalogue (ETKA). Available retaining rings

Pulling tapered roller bearing outer race out of clutch housing A -  Counter support, e.g. -Kukko 22/2- B -  Internal puller, 46 ... 58 mm, e.g. -Kukko 21/7-

Tapered roller bearing outer race installation position in clutch housing The recesses for locking plate ( → Fig.) on tapered roller bearing outer race -arrow A- and clutch housing -arrow  B- must align.

Pressing in tapered roller bearing outer race –  After pressing in, check if the locking plate -A- can be inserted in the recess.   Note! t  The locking plate may be inserted only after the input shaft has been installed and tightened. t  Otherwise, the inner race of the tapered roller bearing may come in contact with the securing bolt for the outer race when the input shaft is inserted, damaging the inner race.
