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 anticlockwise 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.
