Unit Startup
Figure 111. Retaining clip location
Note: Pile seal brackets are fixed with a single screw to
the cassette frame near the ends of the wheel
bearing beam. Because the height of the belt link is
slightly higher than that of the urethane belt, a rare
interference may occur when it passes the seal
bracket. If this occurs, remove the interfering
bracket(s). No measurable change of performance
will occur.
Seal Adjustment
WARNING
Hazardous Voltage!
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Do not open the service access
doors while the unit is operating. Failure to disconnect
power before servicing could result in death or serious
injury.
1. Disconnect all electrical power.
2. Loosen the diameter seal adjustment screws and back
the seals away from the wheel surface, see
3. Rotate the wheel clockwise until two opposing spokes
are hidden behind the bearing support beam.

4. Using a folded piece of paper as a feeler gauge,
position the paper between the wheel surface and the
diameter seals.
5. 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.
6. Check the seal adjustment through a full rotation of the
wheel. Re-tighten the adjusting screws and recheck the
clearance with the paper-feeler gauge.

disconnect power before servicing could result in death
or serious injury.
1. Disconnect all electrical power.
2. Remove the belt from the pulley and position it
temporarily 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
earlier in this procedure.
