Routine Maintenance
with vise grip to prevent wheel rotation (see
Figure 199).
2. Remove 1/4-20 flat head screw from segment nose
bracket.
3. Center and rest segment on lower spoke. Slide
segment on spoke until nose bracket contacts stop in
hub plate. Insert screw and tighten until screw is firmly
seated (see Figure 200).
4. Holding wheel to prevent rotation, remove vise grip.
Rotate wheel clockwise to install segments in the order
shown in Figure 198.
5. Secure pulley. Repeat steps 2 through 4 until all inner
segments are installed.

Installation Procedure for Outer Segments

1. Align segment opening with pulley. Secure pulley and
belt with vise grip to prevent rotation (see
2. Rotate outer segment retainer latch, located at end of
spokes, 90 degrees from rim and remove two forked
outer segment retainers.
3. Install outer segment by starting lower end in position
and pressing straight in against four corners. Sharp
rap with heel of hand will assist entry when needed
(see Figure 201). Note: Only reinstall segment retainer
between adjacent installed segments.
4. Rotate both retainer latches to closed position to
prevent interference with bearing support beam while
rotating wheel by hand.
5. Repeat steps 1 through 4 in the order shown in
Figure 198until all outer segments are in place. Make
certain all retainer latches are latched in place under
catch.

Energy Wheel Bearings/Motor/Belts

The wheel drive motor and wheel support shaft bearings
are permanently lubricated and no further lubrication is
necessary.

Energy Wheel Bearing/Drive Belt

The drive belt is a urethane stretch belt designed to
provide constant tension throughout the life of the belt. No
periodic adjustment is required. Inspect the belt annually
for proper tracking and tension. A properly tensioned belt
will turn the wheel immediately, with no visible slippage,
when power is applied.
Sharp Edges!
Failure to follow the instructions below could result in
minor to moderate injury. The service procedure
described in this document involves working around
sharp edges. To avoid being cut, technicians MUST put
on all necessary Personal Protective Equipment (PPE),
including gloves and arm guards.
Bearing/Drive Belt Replacement for Sizes 10-
50
Bearing removal on the pulley side of the wheel is required
to remove and replace the drive belt for unit sizes 10 to 50.
Bearing removal is discussed first in this procedure.
1. Disconnect all electrical power.
2. Obtain access to the pulley side bearing access plate.
3. Remove the two bearing access plate retaining screws
and the access plate.
4. Using a hexagonal wrench, loosen the set screw in the
bearing locking collar.
5. Using a light hammer and a drift placed in the drift pin
hole in the collar, tap the collar in the opposite direction
of wheel rotation to unlock it.
