Belt Tension

Frequently inspect the V-belt tension during the first twenty hours of operation. During this period, the belts will stretch a little.

To adjust belt tension, lower the motor slightly by loosening the lower check nuts shown in Figure 40. When belt tension is satisfactory, tighten the upper check nuts down onto the motor bracket to secure it.

DO NOT over-tighten the check nuts—too much pressure at the wrong angle may break the motor mount casting ears.

Pulley Alignment

The V-belt pulleys should be properly aligned with each other to prevent premature belt wear. Check the alignment with a good quality straightedge as shown in Figure 41.

To align the pulleys:

1.Loosen the belt tension check nuts so the motor will freely move up and down.

2.Loosen, but do not remove, the 4 bolts that secure the motor to the motor mounting plate.

3.Slide the motor as needed to align the pulleys.

4.When the pulleys are aligned, tighten the 4 motor mount bolts.

5.Tension the V-belts and replace the belt cover.
