The motors on 36 and 42Vxx machines rest on a spring tensioned motor mount plate. Any
misalignment between this motor mount and the drive pulley results in excessive drive belt twist
and stress, greatly reducing belt life. Check motor mount to drive pulley alignment whenever
excessive drive train dust is noted, or whenever any type of drive train service (belt replacement,
main bearing or motor replacement) is required.

1. Lock out and tag out power to the machine.
2. Remove rear pulley cover.
3. Set the angle of the contractors square at 90 degrees.
4. Hold the square flush against the drive pulley (Figure 2 and Figure 3).
5. If the bottom straight edge of the contractors square does not rest flush against the motor (as
shown in the Figure 4 example), note which end of the motor must be shimmed to eliminate
the gap.
6. Loosen the bolt securing the motor mount plate to the channel weldment. Bolt should be just
loose enough to allow shims to be inserted between the motor platform and the channel
weldment beneath (Figure 5).
