A.J.S. 16 Instruction Book - A Cam Ring Adjuster
On a new machine, or after replenishment, oil may leak from this bearing. This is of no
consequence and the leakage will cease after a few hundred miles have been covered.
The rear wheel fork is suspended on springs located in the two suspension units joining
the rear fork to the main frame loops.
The suspension units are of the sealed unit type, and topping up is not necessary. The
springs are lubricated before assembly and the fluid in the damper unit is the exact
quantity and sufficient for the unit's life.
An exploded view of the suspension unit is shown in illustration 31.
Maintenance is confined to external cleaning and occasional greasing of the cam ring
adjuster.
Should a squeak or rubbing noise develop as the units move, remove the split collar
securing the top cover tube, remove unit top fixing bolt, take off the tube and apply
grease on the outside diameter of the spring.
A CAM RING ADJUSTER
Raising the base of the spring by turning the cam ring clockwise (see illustration 31),
pre-loads the spring for varying loads.
Stronger springs are available for use when a sidecar is attached to the machine.
PROP STAND
The prop stand hinges on a bolt which passes through a lug brazed to the frame and screw
into the jaw of the stand leg. It is then locked by a nut and split pin. Care in tightening
this bolt is necessary to avoid pinching, and it is essential to observe after securely
tightening the lock nut that the stand is perfectly free. Smear the hinge bolt with engine
oil before replacing it.
CENTRE STAND
The centre stand is mounted on a bolt set across the bottom rear of the main frame and Is
removed by taking off a nut of the centre bolt and pushing bolt through the frame.
During removal and replacement the stand should be in a horizontal position in order
to take as much of the tension off the return spring as is possible.
TO REMOVE OIL T A N K
Remove the twinseat.
Remove the frame cover. It is held in position by two large knurled and slotted screws.
Remove the oil tank drain plug and empty the tank.
Disconnect the oil feed and return pipes from the bottom of the tank.
The tank is then held by a bolt at the top front of the tank and a further bolt at the
bottom front. Remove bolts and washers, lift the tank away from the frame a few
inches, and disconnect the vent pipe. The tank is now free. To refit, reverse the
foregoing instructions.
TO REMOVE T H E REAR C H A I N GUARD
Remove the rear wheel. (See Wheel Section.)
Remove the bolt retaining the front end of the chain guard to the rear fork.
Remove the bolt retaining the rear end of the chain guard to the rear fork. (There Is.
one spacer on this bolt, between the two sides of guard.)
