Maintenance

•
Ensure that the brush is parallel to the roller with
1.5 mm (0.060 inch) clearance to light contact.
•
Grease the fittings every 50 hours and after every
washing.
•
When replacing a roller brush, torque the J-bolts
to 2 to 3 N∙m (20 to 25 in-lb).
•
When replacing the brush-shaft-driven pulley,
torque the nut to 36 to 45 N∙m (27 to 33 ft-lb).
•
When replacing the brush-drive pulley, apply 242
Loctite (blue) and torque the bolt to 20 to 26 N∙m
(15 to 19 ft-lb).
Note:
The roller brush, the idler bearing, and the belt
are considered consumable items.
Checking the Pulley
Alignment

Ensure that the belt is properly
tensioned prior to checking the alignment.
1. Lay a straightedge along the outer face of the
drive pulley (Figure
Important:
Only lay the straightedge across
the drive pulley, do not lay it across the drive
and the driven pulley.
2. Ensure that the outer faces of the drive pulley
and the driven pulley are in line within 0.76 mm
(0.030 inch).
Important:
Do not use the idler pulley to
check the alignment.
3. If the pulleys are not aligned, refer to
the Pulley Alignment (page
