Push out the fork damper piston rod from the
axle holder of the slider by pushing the fork
damper.
Apply pressure to the fork damper and insert
the piston base (5) or mechanic's stopper tool
between the axle holder and lock nut (2).
Measure the thread length again.
Standard: 11 – 13 mm (0.43 – 0.51 in)
