The brush drive belt may fail prematurely if the pulleys are not
properly aligned.
9. Using a straight edge, move the roller brush as necessary to align the pulleys.
10. Tighten the roller brush bearing locking collars.
A. Slide the locking collars outward onto the bearing collars. Rotate the
locking collars by hand in the direction of normal brush rotation until the
collars are tight on the shaft.
B. Using the blind hole in the bearing locking collar as an impact point,
lock each collar by striking it with a punch in the normal direction of the
brush rotation.
C. Tighten the set screw in the locking collars to secure the bearing
assembly to the brush shaft.
D. Check the brush assembly for end-play and adjust the bearings if
necessary.
If brush to roller contact is incorrect, brush operation will be
adversely affected.
11. Check that the roller brush is parallel to the rear roller within 0.25 mm (0.010
inch) clearance to light contact. Adjust the roller support or drive plate
as necessary.
12. Install and adjust the drive belt and install the cover.
13. Lubricate the grease fittings on the brush support and the drive plate until
grease is visible. Wipe up any excess grease.
