DRIVE BELT
Belts will stretch in normal use. Properly
adjusted, a 5 pound force applied to the belt
between the motor pulley and the pump will
deflect the belt about 1/2”.
TO ADJUST DRIVE BELT:
1. Remove belt guard cover.
2. Loosen the four fasteners holding the motor to
the top plate.
3. Shift the motor in the proper direction. The
belt must be properly aligned when adjustment is
made.
4. To align belt, lay a straight edge against the
face of the flywheel touching the rim at two
places.
5. Adjust flywheel or motor pulley so that the belt
runs parallel to the straight edge.
6. If necessary, use a gear puller to move the
pulley on the motor shaft. Tighten set screw after
pulley is positioned.
7. Check for proper belt tension (see diagram).
8. Tighten the four fasteners holding the motor to
the top plate.
