Bearing Removal and Preparation

Remove any burrs from the shaft by sanding

Slide new bearings onto the shaft to the desired location and loosely mount bearings onto the bearing support

Ensure bearing bolts and setscrews are loose enough to allow shaft positioning

Tighten the bearing bolts securely to the bearing support

Loosen motor plate adjustment bolts and slide motor plate so that belts easily slip into the grooves on the pulleys.

Slide motor plate until proper tension is reached, ensuring a deflection of approximately 1/4” per foot of center distance.

Lock the motor plate adjustment bolts in place.

Ensure pulleys are properly aligned.

Verify the following conditions after adjustment

Is the belt tension within the acceptable range?

Describe any issues encountered during the adjustment process.

Are there lubrication instructions on the motor nameplate?

Inspect motor bearings for relubrication provisions

Is the motor operating under severe conditions?

Is the motor installed with a vertical shaft?

Drill two holes with 1/4” diameter

Work puller slowly to back wheel off the shaft

Inspect motor nameplate for lubrication instructions

Determine if motor bearings have provisions for relubrication

Check for severe application conditions

Lubricate motor bearings with selected grease

Inspect, clean, or repair bearings as needed

Reduce lubrication interval for vertical shaft installations
