9 | If the fork action is stiff, slacken the axle nut and the fork end clamping nut and move the forks up and down to allow the fork tubes to take up alignment on the axle. Re-tighten the nuts. If stiffness still remains, release fender stay bolts and move forks up and down, finally retightening the stay bolts.
No adjustment to the brake operating mechanism is required. Apply the brake several times to refill the caliper and restore brake pressure.

### SECTION H7

### DISMANTLING FRONT HUB, DISC TYPE

To gain access to the front wheel axle and bearings, remove the wheel as described in Section H6. It is not necessary to remove the brake disc. Proceed as follows:
1 | Unscrew the bearing locking ring (left hand thread) from the left side of the hub using peg spanner 063965 or, if not available, a pin punch and hammer. If the ring is an extremely tight fit, try tapping from different holes and heat the hub with a gentle flame.

2 | Lift away the seal and spacer.
3 | Heat the alloy wheel hub with hot water only to a temperature of 100°C.
*4 | Insert a bar into the bearing spacer tube and force the spacer over fractionally. This will provide just sufficient room to allow a drift to abut on the inner race of the bearing to be removed.
5 | Using a suitable drift to the bearing inner race start to drive the single row bearing out. Force the spacer tube over to the other side of the hub and tap on the inner race at the new point. Continue this operation until the bearing is driven out.
*At a later stage an expanding drift will become available which can be placed into the bearing inner race and expanded by the centre bolt to grip the inner race. The tool and bearing together can then be driven out together from the other side of the hub.
6 | Lift out the bearing spacer tube. If this has been damaged and cannot be corrected, a new spacer should be obtained for reassembly.
7 | Using a suitable sized drift through the hub towards the remaining bearing, drive the double row bearing out of the hub, taking with it the washers and felt scal.
Reassembly of the disc brake front hub is a similar procedure to that detailed fully for the drum brake wheel (Section H6).

### SECTION H8

### REMOVING AND REFITTING FRONT WHEEL

(Drum Type Brake)
To remove the front wheel, support the motorcycle securely on the centre stand so that the front wheel is clear of the ground.
1 | Disconnect the front brake cable at the brake cam lever by taking out the clevis pin after removal of the spring clip.
2 | Unscrew the brake cable adjuster.
