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 20 to 26 N∙m (15 to 19 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 and Adjusting the
Pulley Alignment
1. The driven pulley (at the roller-brush shaft) can
move in or out (
Figure 23 ).
Note:
Make note of which way the pulley needs
to move.

2. While rotating the reel, which rotates the drive
pulley, pry the belt off the drive pulley (
Figure 23
Note:
Wear a padded glove or use a heavy rag
to rotate the reel.
3. Remove the locknut securing the driven pulley
to the brush shaft (
Figure 23 or Figure 24 ).
Note:
Use a 1/2-inch wrench on the roller-brush
shaft flats to keep it from rotating.
4. Remove the driven pulley from the shaft ( Figure
24 ).
5. If the pulley needs to move out, add a 0.8 mm
(0.032 inch) thick washer (
Figure 24 ).
Note:
If the pulley needs to move in, remove
the existing 0.8 mm (0.032 inch) thick washer.
6. Install the pulley.

7. While holding the flats of the roller-brush shaft,
secure the driven pulley on the shaft with the
flange nut (3/8–16) previously removed.
Note:
Seat the locknut; then torque it to 20 to
26 N∙m (15 to 19 ft-lb).
8. Install the belt onto the pulleys as follows:
A. Loop the belt around the drive pulley and
then over the top of the idler pulley ( Figure
25 ).

C. Use a 9/16-inch deep-well socket to rotate
the brush assembly and guide the belt onto
the driven pulley (
Figure 26 ).
