5.3.3 Adjusting Main Drive Belt

As per The Gates Rubber Company the best tension
for a V-Belt drive is the lowest tension at which the
belts will not slip under the highest load condition.

In this manner the method that is used by United’s
technicians is the twist method. The tension of the
turret belt should allow the technician to twist the
belt to the halfway point. If the belt can be twisted
past the halfway point then the belt must be
tightened. If the belt does not twist to the halfway
point excess stress is being applied to the belt and
bearings and may cause these components to fail
prematurely.

For belt adjustment follow the procedures below:

1.

Turn OFF the power at the safety disconnect and lock the handle in this position.

2.

Loosen the four (4) retaining bolts holding the main drive motor to the motor base.

3.

Use the adjustment bolt on the rear of the motor base to move the motor backwards to
tighten the belt, or forward to loosen the belt.

4.

Recheck the tension on the belt and adjust if necessary.

5.

Tighten four (4) retaining bolts holding the main drive motor to the motor base and torque to
30 ft-lbs.

Note: It is important the motor remains parallel to the turret. Before retightening check motor with
straight edge or square for alignment with turret.

5.3.4 Replacing Main Drive Belt

1.

Empty ALL barrels, insert into the cradles and latch cradle lids.

2.

Turn OFF the power at the Safety Disconnect and lock the handle in this position.
