Counter bearing side:
– All M24 fine-thread screws (16) are right-hand thread (!). The tightening torque is
750 Nm. They must not be coated with liquid thread-lock (Loctite).
– Mark them in pairs before unscrewing the top (17) and bottom half-shell (18).
These parts are precisely manufactured and cannot be exchanged with other parts
or combined with other parts.
– Remove the two M12 hexagonal screws (19) and remove the top half-shell (17)
with the locking plate (20) and the screw lock washer (21).
Removing and inserting roller:
– To lift a roller out, it must be lifted until it is above the bottom half-shell (18). This is
best done with an in-house manufactured hook that grips the roller. A roller weighs
approx. 150 kg. The lifted roller will tilt slightly on the coupling lug. The roller can be
detached from the coupling lug by tapping the roller coil lightly in an axial direction.
– When reassembling always replace both O-rings (ROPA item no. 412030900) (22)
on the fastener (23) with the new O-rings. The same applies to the O-ring (ROPA
item no. 412032000) (24) in the grease duct in the bottom half-shell.
– The hexagonal screws (19) must be tightened to a torque of 85 Nm. The
screws are locked by bending up the corners of the screw locking plate (ROPA
item no. 100273600) (21).
– When inserting the fastening bracket (23) in the anti-rotation washer (25) make
sure that the lubrication hole (26) in the fastening ball must always opposite to the
slot (27) in in the lock washer (25).
