Ensure slack in each belt is on the same side of the drive after replacement

Measure belt deflection halfway between sheave centers (in inches)

Ensure the unit is attached to the designed system

Momentarily energize the unit to check wheel rotation

Is the wheel rotation in the same direction as the airflow at the outlet?

Does the wheel rotation conform to the rotation decal affixed to the unit?

Describe any issues noted during the check

Loosen the inlet cone/ring bolts

Center the cone/ring on the wheel

Is additional adjustment required to maintain a constant radial gap?

Loosen the bearing bolts and center the wheel if necessary

Loosen the wheel hub from the shaft

Move the wheel to the desired position along the shaft

Check for a smooth transition between the inlet cone and wheel

Ensure power source is locked out

Loosen and remove belts and pulleys

Disconnect extended lubrication lines at the bearing

Read and follow all instructions carefully

Ensure driven sheaves and belts have been removed

Remove shaft black coating with solvent
