8. (Dis)Mounting procedures for shaft no. 3

8.1 Mounting bearing 22318 EK/C3 on shaft no. 3

The tightness of the it between the bearing, withdrawal sleeve and the shaft depends on
how far the bearing is pressed onto the tapered seat.
Therefore, it is necessary to measure the radial clearance of the unmounted spherical roller
bearing (see section 6.2), Push the spacer-ring, the spherical roller bearing and withdrawal
sleeve onto the shaft. Screw the hydraulic nut, with the piston turned away from bearing
onto the withdrawal sleeve. Ensure that a gap between the bearing side face and the back
face of the hydraulic nut is at least as great as the required axial drive up. Use the support
nut as a stop for the piston of the hydraulic nut.
Connect pump 729124 DU to the hydraulic nut and pump until the required reduction
of clearance has been reached (see section 6.2). Stop pumping and release the pressure
in the hydraulic nut. Unscrew the support nut and the hydraulic nut and secure the
withdrawal sleeve with the shaft nut and locking washer. Recheck the inal clearance of
the bearing.

8.2 Dismounting bearing 22318 EK/C3 on shaft no. 3

Use hook spanner HN 17 to loosen shaft nut KM 17. Remove shaft nut KM 17 and locking
washer MB 17. Screw the hydraulic nut to the withdrawal sleeve ,with the piston facing the
bearing, until the piston is touching the bearing inner ring. Pump oil into the hydraulic nut
with pump 729124 DU until the bearing becomes detached from the sleeve. Remove the
pump and unscrew the hydraulic nut. Draw out the withdrawal sleeve entirely and remove
the bearing.
