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.
