To Refit Rear Wheel; Wheel Bearings And Adjustment; To Dismantle Front Wheel Bearings - A.J.S. 16 Instruction Book

Disconnect the speedometer drive cable from the drive. Release the rear wheel spindle
nut several turns, pull the wheel to the right, until the brake plate clears the anchor
boss on the frame.
Take the chain off its sprocket, the wheel can now be removed. Lean the machine at
an angle, take the wheel away under the silencer.
TO REFIT REAR W H E E L
Refit in the reverse order described for removal, with caution to ensure the brake
plate is correctly anchored (see illustration 40).
Position the speedo drive and connect cable before tightening the wheel spindle nut.
If pressure is applied on the rear brake pedal, during the process of tightening the spindle
nut, this will centralise the brake shoes.
Verify the closed end of the chain link spring clip is facing the direction of chain travel.
WHEEL BEARINGS A N D ADJUSTMENT
The wheel bearings are of taper roller type (see illustrations 33 and 34). The outer cup
for the rollers are pressed into the hub shell. They have a fixed location one side and an
adjustable location on the other. The fixed location is provided by a circlip in a groove
cut in one end of the hub shell, while the adjustable location is regulated by a screwed
ring that is threaded into the opposite end of the hub and the position of which can be
locked by an encircling nut.
On each wheel the adjusting ring is located on the right-hand side.
It is rarely necessary to make adjustment to wheel bearings. It is most important they
are not adjusted too tightly as this would quickly ruin them. There must always be a
slight amount of end play. This should be about ·002", which represents a just perceptible
rim rock.
A service method of ensuring correct adjustment is:
Slacken the lock nut.
Tighten the adjusting ring until all slackness has been taken up.
Slacken back the adjusting ring exactly one-half turn.
Tighten the lock nut, making sure that, when doing so, the adjusting ring does not creep
round, and the cover disc positioned to permit grease gun application to the nipple.

TO DISMANTLE FRONT WHEEL BEARINGS
