BELT PM9-PWBS14-321

1: Remove covering over motor
2:Remove worn belt by removing lower pully and lowering motor
3: Replace and align lower pully with upper pully
5: Tension belt by raising motor

The motor is heavy and difficult to lift to get the proper tension. Took another person to assist.

1. I had to use an end wrench and a socket wrench to loosen the bolts mounting the motor to a flange. This allowed the motor to slip down the tracks as far as it would go.
2. The electric motor was too heavy to lift by myself so I had to use a car jack to lift it high enough to get the belt on the motor pulley.
3. Once the bel ... Read more t was around both pulleys I lowered the motor, but this left the end opposite the driveshaft to sag down, and rotating the pulleys would throw the belt off.
4. I then had to have my wife help push down on the front of the motor to apply proper tension to the belt, while I used a piece of lumber to lift the back end to keep the motor level.
5. I then was able to tighten the mounting bolts to hold it in place.
6. The final step was advancing the pulley opposite the motor forward until the belt was straight and the two pulleys were coplanar.
7. What made the job difficult was the limited and cramped space to work in the motor housing and the weight of the motor. It really is a two-person job.

Powermatic bandsaw was dangerously over stressed attempting to reduce wet wood to a manageable size for turning on a lathe. The set screws sheered, pulley on lower wheel vibrated loose and shredded the drive belt. Repair was easily accomplished by installing new pulley and new drive belt.

Adjusted motor to fit new belt.
