10Remove the rear wheel (see Chapter 7). Slacken the sprocket nuts before pulling the sprocket coupling out of the hub.
11Lift the sprocket coupling out of the hub, unscrew the nuts securing the sprocket to the coupling and remove the sprocket, noting which way round it fits (see illustrations).
12If necessary, remove the rubber damper ring from the flange riveted to the outer face of the sprocket and renew it if it is worn or damaged (see illustration).
13Install the sprocket onto the coupling with the stamped tooth number marking and riveted flange facing out. Apply some engine oil to the threads of the nuts and tighten them hand-tight.
14Press the coupling into the hub and tighten the nuts to the torque setting specified at the beginning of this Chapter.
15 Install the rear wheel (see Chapter 7), then adjust and lubricate the chain following the procedures described in Chapter 1.
16 Sprocketcoupling/rubber
damper- check and renewal ^
1 Remove the rear wheel (see Chapter 7).
2 Lift the sprocket coupling out of the hub (see illustration 15.11a).The coupling should be a press fit between the rubber dampers with no freeplay. Check the coupling for cracks and damage, and renew it if necessary.
Inspect the coupling dampers for wear and deterioration
3Remove the rubber dampers from the hub and check them for cracks, hardening and general deterioration and renew them if necessary (see illustration).
4Check the condition of the coupling O-ring and renew it if it is damaged or deteriorated. Smear the O-ring with grease before installing the sprocket coupling onto the hub.
5 Checking and renewal procedures for the coupling bearing are in Chapter 7.
6 Installation is the reverse of the removal procedure.
