Toro Reelmaster 5010- H, Installation Instructions Manual

Page: 10 / 16

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
Important:
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 21 ).
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 Adjusting
the Pulley Alignment (page 10) .
Important:
The belt may fail prematurely if
the pulleys are not properly aligned.

Adjusting the Pulley
Alignment
1. The driven pulley (at the roller-brush shaft) can
move in or out (
Figure 22 ).
Note:
Make note of which way the pulley needs
to move when checking the belt alignment; refer
to
Checking the Pulley Alignment (page 10) .

2. While rotating the reel, which rotates the drive
pulley, pry the belt off the drive pulley (
Figure 22
Important:
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 22 or Figure 23 ).
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
23 ).
5. If the pulley needs to move out, add a 0.8 mm
(0.032 inch) thick washer (
Figure 23 ).
Note:
If the pulley needs to move in, remove
the existing 0.8 mm (0.032 inch) thick washer.
6. Install the pulley as shown in Figure 23 .
