[283] Mounting mandrel for friction bearing bushings

Auxiliary materials:
– Loctite 648 adhesive
– Loctite 243 Threadlocker
– Multi-purpose grease

Replacing friction bearings



Fold pressure roller out of working position.



Remove 2 screws [280B], remove the
handhold [280A].



Screw the knurled thumbscrew [281A] all of the way
out and remove the pressure roller along with clam-
ping ring.



Push out the friction bearing bushings [282A].



Push the friction bearing bushings into the pressure
roller with the mounting mandrel.



Thoroughly grease friction bearings. The lubrication
pockets [282arrow] in the friction bearing bushings
must be completely filled with grease.



Install the pressure roller



Clean the threads of the screw joints [280B] atta-
ching the handhold to the pressure roller then screw
screws back in, using Loctite 243.
