• Attach the stopper ring securely to the stopper ring groove of
the outer tube.
• Attach the dust seal 1.
NOTE:
After attaching the dust seal, make sure that there are no cracks
around the circumference of the seal. Cracks could allow water,
mud and the like to enter and cause an oil leak.
Use of grease as a substitute fork oil when installing
the oil seal can result in an oil leak. Applying grease to
the dust seal and oil seal can cause dirt to accumulate
and damage the dust seal lip and oil seal lip.
Use only a thin coat of fork oil on the oil seal.
