7.9.8 Readjusting eccentric bearing shaking share drive
As soon as you find clearance by lateral movement of the fork-type joint of the eccen-
tric bearings, the corresponding bearing must be readjusted.
You will need the special ROPA hook spanner tool for the groove nut M 75 x 2 for this
(ROPA item no. 018016200).
ATTENTION
This work may only be performed by people already having sufficient experience in
adjusting tapered-roller bearings.
Readjust the bearings so far until they are without any clearance. When the bearing is
without clearance, readjust the adjusting nut so far until the bearing has minimal pre-
stress.
Proceed as follows:
– Push the tooth of the locking disk (1) out of the groove.
– Readjust the bearing.
– Bend the suitable tooth back into the groove.
