magnet are correctly adjusted and aligned. All of the checks described in this procedure must be
performed to ensure proper operation.

Input Drive Assembly Axle Alignment
4.
Rotate one of the crankarms to the twelve o’clock position and measure the distance from
the crankarm to the frame weldment. See Diagram 5.6. Rotate the opposite crankarm to the
twelve o’clock position and measure the distance from the crankarm to the frame weldment.
If the two measurements are different by more than 1/16 inch, continue with step 5. If the
two measurements are within 1/16 inch, skip to the “input drive axle to step up pulley axle
alignment” procedure.

On the side with the larger measurement, loosen the upper pillow block mounting bolt only,
do not loosen the lower pillow block mounting bolt. On the side with the smaller
measurement, loosen both pillow block mounting bolts. See Diagram 5.7. For purposes of
illustration we will assume that the left measurement was larger than the right side
measurement in Diagram 5.7.
