After making adjustments to the front chain always check the adjustment of the rear chain.
Slacken or tighten as necessary.
REAR CHAIN ADJUSTMENT
To obtain rear chain adjustment the rear wheel is bodily moved in the rear frame fork
ends which are slotted for the purpose. Adjusting screws with lock nuts are provided
at each slotted end.
To adjust the chain place cycle on stand and slightly slacken wheel spindle end nut also
slightly slacken the brake drum dummy spindle locknut, the hexagon of which is
adjacent to the spindle end nut. Then slacken back the adjuster screw lock nut on each
side and screw each adjuster bolt in turn further out until the correct chain tension is
obtained, taking care to move each side adjusting screw exactly the same amount.
While on the stand the chain whip should be 1
8
" (see notes below). Then retighten
spindle end nut or nuts and also the adjuster screw lock nuts. Chain whip must always
be checked midway between the two sprockets and the rear wheel should always be
turned to obtain the position of least slackness. This is because rear chains rarely wear
evenly and there is usually one position at which the chain is tighter than at any other.
It is at this tightest position that the adjustment check should be made.
NOTE—The chain adjustment specified while cycle is on the stand is reduced to ½" when
the wheel is on the ground and rider seated. This is due to chain sprocket
centres varying slightly as the result of movement of the rear swinging arm.
