Belt Replacement
1.
Obtain access to the pulley side
bearing access plate if bearing access
plates are provided. Remove two
bearing access plate retaining screws
and the access plate.
2.
Using hexagonal wrench, loosen set
screw in bearing locking collar. Using
light hammer and drift (in drift pin
hole) tap collar in the direction of
wheel rotation to unlock collar.
Remove collar.
3.
Using socket wrench with extension,
remove two nuts which secure
bearing housing to the bearing
support beam. Slide bearing from
shaft. If not removable by hand, use
bearing puller.
4.
Form a small loop of belt and pass it
through the hole in the bearing
support beam. Grasp the belt at the
wheel hub and pull the entire belt
down.
Note:
Slight hand pressure against wheel rim
will lift weight of wheel from inner race of
bearing to assist bearing removal and
installation.
5.
Loop the trailing end of the belt over
the shaft (belt is partially through the
opening).
6.
Reinstall the bearing onto the wheel
shaft, being careful to engage the two
locating pins into the holes in the
bearing support beam. Secure the
bearing with two self-locking nuts.
7.
Install the belts around the wheel and
pulley according to the instructions
provided with the belt.
8.
Reinstall diameter seals or hub seal
and tighten retaining screws. Rotate
wheel in clockwise direction to
determine that wheel rotates freely
with slight drag on seals.
9.
Reinstall bearing locking collar.
Rotate collar by hand in the direction
the wheel rotates (see label provided
on each cassette for wheel rotation).
10.
Lock in position by tapping drift pin
hole with hammer and drift. Secure in
position by tightening set screw.
