Cast Iron Taper Bushing

TO ASSEMBLE:

1. Clean and degrease the bore and taper surfaces of the bush and the tapered bore of the pulley. Insert the bush into the pulley hub and line up holes (half thread holes must line up with half unloading holes).

2. Lightly oil the grub screws (bush size 1008-3030) or oil the cap screws (bush size to 5050) and screw them in but do not tighten yet.

3. Clean and degrease the shaft. Fit pulley with taper bush on shaft and place in your desired position.

4. When using a key, it should first be fitted in the shaft keyway. There should be a top clearance between the key and the keyway bore.

5. Using a hexagon socket wrench (DIN911) gradually tighten the grub cap screws in accordance with the torques listed in the schedule.

6. When the drive has been operating under-load for a short period of time (roughly half an hour), check and ensure that the screws remained at the appropriate tightening torque.

7. In order to eliminate the ingress of dirt, fill all empty holes with grease.

REMOVAL

1. Loosen and remove all screws and place them in the holes of the bushing.

2. Tighten the screws alternatively till the hub’s grip on the bushing is loosened. The inner bore of the bushing can be slid on the shaft.

Remove the bushing from the shaft.
