Maintenance
13. Unplug motor wires. Loosen end cap screws, 1
full turn.
14. Back off set screws to release belt tension.
15. Remove the motor clamps and lift brackets.
16. Remove belts and belt covers.
17. Lift motor out of housing. Remove pulleys and
adjustment bracket with screw. Set parts aside
for re-installation.
18. Take the new motor and loosen the screws in the
long rear drive end cap. This allows the end cap
to swivel +/- 20 degrees. Do not remove the end
cap screws, only back them off 1 full turn. Install
adjustment bracket to the opposite end. Torque
to 40 in-lbs (4.5Nm)
19. Put the motor in the cradle on the frame. Place
pulleys onto motor shaft's. Loop the drive belt
onto the right motor drive pulley
NOTE: Do not let the pulleys extend more than
0.5mm (0.02in) past the motor shaft.
20. Reinstall the motor clamps, only tighten the rear
screws. The front screws will be tightened later.
21. From the bottom, remove the left driver plate
(front brush).
22. Loop and align the belt on the motor pulley.
23. Install one screw from the service kit (P/N 9.841-
005.0) into the pulley, captured by the belt.
24. Rotate the pulley to install the second captured
screw.
25. Use the 2 screws to rotate the assembly to install
the third screw.
26. Rotate the pulley and guide the belt onto the
pulley. To ensure proper alignment, reverse
rotation may be necessary. Use caution when
prying against the frame.
27. Gently pry the motor up from the frame and
tighten the left set screw. Use the kit’s distance
tool to center the motor and set the belt tension.
28. Repeat the previous step for the right set screw.
29. Place lift brackets on motor, align over pins.
30. Tighten the screw in the long gear drive cap.
31. Tighten all four motor clamp bolts.
32. Check both belts for equal tension. The belts
should not sag under their own weight, however,
should flex easily when squeezed with fingers. If
the tension is clearly unequal, loosen the motor
mount bolts and retighten. This will equalize the
belt tension from on side to the other.
33. Reinstall finger guards.
