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.
TAPER-LOCK BUSHING REMOVAL
A Remove any loading to the equipment to enable a safe removal of components.
Slacken and remove all locking screws.
B
C Add lubricant to the previously removed screws and insert into jack-out hole/holes in the bushing.
D Tighten the screws uniformly and alternately until the bushing is loose and the pulley/hub/sprocket can be moved freely on the shaft.
E Remove the bushing/pulley/hub/sprocket assembly from the shaft.
