Check Wheel Drive Components
Motor - The motor bearings are pre-lubricated and do not need additional lubrication.
Clean any dirt from the air cooling ports in the motor housing.
Pulley - The pulley is secured to the drive motor shaft by a set screw. The set screw
is secured with removable Locktite to prevent loosening. Confirm the set screw is
secure.
Belt - The belt is of urethane stretch material and is designed to provide constant ten-
sion. There is no type of adjustment. Inspect the belt for proper tracking and tension.
If a belt needs replaced, it must be replaced with a factory-authorized replacement
(see P/N’s below). Follow the wheel manufacturer’s instructions.
NOTE: A properly tensioned belt will turn the wheel immediately after power is
applied with no visible slippage during startup. The belt should track approximately
1/4” from the outer edge of the rim. If the belt or any other component needs
replaced, use only factory-authorized replacement designed for the purpose. Follow
instructions provided by the wheel manufacturer.
□ Fold the piece of paper to use as a feeler gauge. Position the folded
paper between the wheel surface and the seal. Turn the wheel so that
the seal is lined up with a segment spoke.
□ Adjust the seal toward the wheel surface and slide the feeler gauge
(folded paper) along the length of the spoke. When a slight friction
is detected on the feeler gauge (folded paper), tighten the screws.
Recheck the clearance with the feeler gauge.
□ Repeat the procedure on the other three seals.
□ When the unit is started, start and stop the wheel several times to verify seal
adjustment and to confirm that the belt is tracking properly on the wheel rim.
The belt should be approximately 1/4” from the outer edge of the rim.
