If the drive chain free movement
measurement is incorrect, adjustments
must be made as follows:
• Loosen the wheel spindle nut.
• Loosen the lock nuts on both the
left hand and right hand drive chain
adjuster bolts.
• Move both adjusters by an equal
amount using the adjuster markings
as a guideline.
• Turn the adjuster bolts clockwise to
increase drive chain free movement
and counterclockwise to reduce
drive chain free movement.
• When the correct amount of drive
chain free movement has been set,
push the wheel into firm contact
with the adjusters.
• Make sure the same adjuster
marking is aligned with the spindle
adjuster on both sides of the
swinging arm.
• Tighten both adjuster lock nuts to
15 lbf ft (20 Nm) and the rear wheel
spindle nut to 81 lbf ft (110 Nm).
• Repeat the drive chain adjustment
check. Readjust if necessary.
• Check the rear brake effectiveness.
Rectify if necessary.
Warning
It is dangerous to operate the
motorcycle with defective brakes; you
must have your authorized Triumph
dealer take remedial action before you
attempt to ride the motorcycle again.
Failure to take remedial action may
reduce braking efficiency leading
to loss of motorcycle control or an
accident.
