8. Torque the J-bolt locknuts to 2 to 3 N-m (20 to 25
in-lb).
9. Install the excluder seal and the non-drive-bearing
housing onto the brush shaft
10. Mount the non-drive-bearing housing to the
bearing-housing mounting bracket with the 2 bolts,
washers, and nuts previously removed.
Note: Be careful not to knock the seal spring off.
11. Tighten the 2 bolts, washers, and nuts securing the
drive-bearing housing to the bearing-housing mounting

Maintenance

1. Make sure that the brush is parallel to the roller with
1.5 mm (0.060 inch) clearance to light contact.
2. Grease the fittings every 50 hours and after every
washing.
3. When replacing roller brush, torque the J-bolts to 2
to 3 N-m (20 to 25 in-lb).
4. When replacing the brush-shaft-driven pulley, torque
the nut to 36 to 45 N-m (27 to 33 ft-lb).
5. When replacing the brush-drive pulley, torque the bolt
to 47 to 54 N-m (35 to 40 ft-lb).
Important: Backlapping at the incorrect reel
speed may loosen and strip the drive-pulley
threads. Refer to the Cutting Unit Operator's
Manual for the backlapping procedure.
6. The roller brush, idler bearing, and belt are considered
consumable items.

Aligning the Pulleys

1. The driven pulley (at the roller-brush shaft) can move

2. While rotating the reel, which rotates the drive pulley,
pry the belt off the drive pulley
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
Note: Put a 1/2-inch wrench on the flats of the
roller-brush shaft to keep it from rotating.
4. Remove the driven pulley from the shaft
5. If the pulley needs to move out, add one 0.8 mm (0.032
inch) thick spacer
move in, remove the existing 0.8 mm (0.032 inch) thick
spacer.
6. Install the pulley.
