Removing the driven sprocket –  Place extractor -U-40100/1- on the driven sprocket. –  Remove the sprocket.

Removing the roller bearing from the driven sprocket –  Place tool -U-40200/2- with side B facing downwards, on the driven sprocket. –  Place extractor -U-40100/1- on tool -U-40200/2-. –  Remove the bearing.   Note! If the bearing cage breaks on extraction, use tool -T20022- to remove the internal bearing ring.

Fitting the roller bearing on the driven sprocket –  Place the driven sprocket in a press, with tool -U-40200/18- on the bearing. –  Activate the press until the gear is engaged.

Fit the outer track of the roller bearing in the bearing housing –  Put the bearing housing in a press. –  Fit the outer roller bearing track with tools -U-40200/14- and -U-40200/10-. –  Activate the press until the outer track of the roller bearing fits into the bearing housing.

Removing and fitting the crown pinion bearing support ring Removing –  Before removing the crown pinion bearing support ring, remove the safety bolt → Item. –  Remove the crown pinion bearing support ring using tool -T20024-. Installing –  Fit the crown pinion bearing support ring using tool -T20024-. Tightening torque: 200 Nm –  Secure the position of the ring with the safety bolt → Item. –  Fit safety ring with -AKD 456 000 01-.

Fitting position for the the crown pinion bearing support ring seal The open side -arrow- of the seal must be facing the outer roller bearing track.

Fitting the crown pinion bearing support ring seal –  Use tool -T20027- to fit the seal. Assembly position: The open side of the seal should face tool -T20027-.

Removing the crown pinion shaft –  Screw tool -T20025- onto the crown pinion shaft. –  Place tool -T20023- on the gearbox casing so that the three legs are firmly supported. –  Hold tool -T20025- with a flat ring spanner. –  Screw tool -T20025- until the crown pinion shaft is disengaged.   Note! When the crown pinion shaft is disengaged, the lower roller bearing and its corresponding outer track will also become disengaged.

Fit the outer track of the roller bearing on the crown pinion shaft –  Fit the crown pinion shaft in its housing in the gearbox casing. –  Place the outer roller bearing track in its fitting position. –  Fit the outer track of the roller bearing with tools -T20051- and -T20024-. –  Hit with a plastic hammer until the outer bearing track is engaged.

Fit the roller bearing on the crown pinion shaft –  Place the crown pinion shaft in a press, with tool -U-40061/1- installed under the crown pinion. –  Place tools -T20052- and -T20024- on the roller bearing. –  Activate the press until the roller bearing is fitted in its position.
