TAPER-LOCK ® BUSHING INSTALLATION AND REMOVAL TAPER-LOCK ® Bushing Installation 1 Clean and degrease the bore and tapered surface of the bushing and the tapered bore of the pulley/hub/sprocket. 2 Insert the bushing into the pulley/hub/sprocket bore and line up the holes (Half threaded holes must line up the half straight non-threaded holes). 3 Lightly oil the locking screws and insert but do not tighten yet. 4 When using a key, it should be fitted to the shaft keyway. There should be a top clearance between the key and the keyway in the mating bushing. 5 Clean and degrease the shaft. Fit pulley/hub/sprocket onto the shaft and locate in the desired position. 6 Using a hexagon socket wrench, gradually tighten the locking screws in accordance with the required tightening torque. 7 When the drive has been operating under load for a short period, approximately 30 to 60 minutes, stop the equipment and check that the screws remain at the required tightening torque. Adjust if necessary. 8 To avoid the ingress of dirt, fill all empty holes with grease.
