Installing the Pulley
1. Place and position the key into the keyway located on the drive shaft.
2. Place the pulley onto the drive shaft with the set screw side of the pulley facing away from the bearing
plate. (See Figure 4I.) Position the pulley so that it is as close to the lock collar as possible, but
without touching it.
3. Once the pulley is appropriately positioned, tighten the set screw with a hex head wrench to secure
it to the drive shaft. (See Figure 4I.)

Tightening the Lock Collar
1. Use a punch and hammer to drive the lock collar clockwise or in the same direction as the shaft
rotation. Once the lock collar is set in place, use a hex head wrench to tighten the lock collar by
tightening the set screw.
NOTE: If the lock collar is not turned far enough, the set screw will not lock it into place.
