A: Install

2, Lightly oil the thread of the screws and place them loosely into the threaded holes of the hub as shown in the diagram.

4, Using a hexagon wrench, gradually tighten the screws alternately until tight.
5, Hammer against the large end of the bush using a block to avoid damaging the bush. The screws can now be tightened more. Repeat this procedure until the correct wrench tightening torque i achieved from the table below.
6, To achieve the best balance, if a key is not used, position the keyways in the bush and hub diametrically opposite to each other.
7, If a key is to be fitted, locate it in the shaft keyway before fitting the bush. It is essential that a parallel key with top clearance be fitted. Under no circumstances should taper or top fitting keys be used.
8, After the drive has been running for a short time, check the tightness of the screws.
9, Finally, fill all empty holes with grease to exclude dirt and prevent corrosion.
