To assemble
1. Clean and degrease the bore and taper surfaces of the bush and
the tapered bore of the pulley.
2. Insert the bush in the pulley hub and line up the holes (half thread
holes must line up with half straight holes).
3. Lightly oil the grub screws (bush size 1008 to 3030) or the cap
screws (bush size 3535 to 5050) and screw them in, do not tighten
yet.

and locate in desired position.
- 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 in the bore.
- Using a hexagon socket wrench (DIN 911) gradually tighten
the grub/cap screws in accordance with the torques as listed
in the schedule of screw tightening torques
