Energy Wheel Drive Belt Adjustment
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.
Energy Wheel Seal Adjustment
1. Loosen the diameter seal adjustment screws and back
the seals away from the wheel surface.
1. Rotate the wheel clockwise until two opposing spokes
are hidden behind the bearing support beam.
2. Using a folded piece of paper as a feeler gauge,
position the paper between the wheel surface and the
diameter seals.
3. Adjust the seals toward the wheel surface until slight
friction on the paper feeler gauge is felt when the
gauge is moved along the length of the spoke.
4. Check the adjustment through a full rotation of the
wheel.
5. Retighten the adjusting screws and recheck the
clearance with the paper feeler gauge.
Energy Wheel Drive Motor and Pulley
Replacement
1. Disconnect all electrical power.
2. Remove the belt from the pulley and temporarily
position it around the wheel rim.
3. Measure and record the distance from the inner edge
of the pulley to the mounting wall.
4. Loosen the set screw in the wheel drive pulley using an
Allen wrench and remove the pulley from the motor
drive shaft.
5. While supporting the weight of the drive motor in one
hand, loosen and remove the four mounting bolts.
6. Install a replacement motor with the hardware kit
supplied.
7. Install the pulley and adjust it to the distance recorded
in the previous step.
8. Tighten the set screw to the drive shaft.
9. Stretch the belt over the pulley and engage it in the
groove.
CAUTION
Sharp Edges!
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. Failure to follow recommendations could result
in minor to moderate injury.
Figure 93. To adjust seal, loosen screws, back seals
away from wheel surface. Seal seen from
