Replacement
Replacement is the reverse of the removal procedure. Observe the following points at the
appropriate steps.
NOTE: High pressure bearing grease, PL 26.11 Item 3 , is used in the following locations.
• Drum bearing housing in the front drum frame casting.
• Drum pulley bearing housing in the rear drum frame casting.
• Outside diameter of the transfix roller bearing holder at the front of the transfix roller.
During normal removal and replacement the existing bearing grease used during manufacture
will be sufficient. Only apply grease when both sides of any bearing surface are being
replaced, or if the surfaces have been wiped clean. Apply the grease very sparingly.
