11 Rear wheel bearings: removal and replacement
1
Remove the oil seal and remember it has to be replaced by
a new one. If the bearings are worn or rough, both should be
renewed.
2
Tap out the old bearings and fit new ones, using the method
pack with new, clean grease.
and renovation
1
The rear sprocket is mounted on four pins which engage in
bonded rubber bushes pressed into the hub casting. It is
retained by a large circlip, which, when removed, allows the
sprocket to be pulled free complete with the four driving pins.
On older machines, it is possible that the pins may become
jammed in place in the bonded bush centres, in which case, the
four nuts may be removed to allow the sprocket to be detached.
On refitting, tighten the nuts to a torque setting of 5.5 - 6.5 kgf
m (40 - 47 Ibf ft).
2
Should the above condition arise, or if the bushes are worn,
the wheel should be taken to a Honda Service Agent who will
have the equipment necessary to extract the old bushes, and fit
the new ones. It is extremely unlikely that this operation can be
performed at home due to the tight fit of the bushes. In all
probability, any attempt to dislodge them will result in the inner
metal sleeve tearing out of the rubber, making subsequent
removal difficult.
3
Check the condition of the sprocket teeth, if they are
hooked, chipped or badly worn, the sprocket must be renewed.
It is considered bad practice to renew one sprocket on its
own. The final drive sprockets should always be renewed as a
pair and a new chain fitted, otherwise rapid wear will
necessitate even earlier renewal on the next occasion.
13 Adjusting the rear brake
1
If the adjustment of the rear brake is correct, the rear brake
Chapter 5 Wheels, brakes and tyres
pedal will have about 25 mm (1 inch) free play before the brake
commences to operate.
2
The length of travel is controlled by the adjuster at the end
of the brake operating rod, close to the brake operating arm. If
the nut is turned clockwise, the amount of travel is reduced and
vice-versa. Always check that the brake is not binding after
adjustments have been made.
3
Note that it may be necessary to re-adjust the height of the
stop lamp switch if the pedal height has been changed to any
marked extent. The switch is located immediately below the
right-hand side cover. The body of the switch is threaded, so
that it can be raised or lowered, after the locknuts have been
slackened. If the stop lamp lights too soon, the switch should be
lowered, and vice-versa.
