Taper Bush Installation
1. Clean & degrease the bore and taper surfaces of the bush and the tapered bore of the pulley. Insert the bush and
the tapered bore of the pulley. Insert the bush in the pulley hub and line up the holes (half thread holes must line up
with half straight holes).
2. Lightly oil the grub screws and screw them in, do NOT tighten yet.
3. Clean & degrease the shaft. Fit pulley with taper bush on shaft & locate in desired position.
4.
When using a key it should first be fitted in the shaft keyway.
NOTE: There must be a top clearance between the key and the keyway in the bore
5. Using a Hexagon wrench, gradually tighten the grub screws to 48 Nm.
When the drive has been operating under load for a short period (half to 1 hour) check and ensure that the screws
remain at the appropriate tightening torque.
6.
In order to eliminate the ingress of dirt, fill all empty holes with grease.
Taper Bush Removal
1. Slacken & remove the screws, after oiling, point and
thread into the jacking off hole in the bush
2. Tighten screw until the bush is loose in the hub and
pulley is free on the shaft
3. Remove pulley bush assembly from shaft.
IMPORTANT There must be a top clearance between
the key and the keyway in the bush, If the top of the
Key interferes with the taper bush then the bush will not
tighten correctly & will loosen again over a short period
of time.
