6. Make the mechanic’s stopper tool out of a thin
piece of steel (0.08 in (2.0 mm) thick) as shown
if you do not have a special tool.
7. Hold the fork center bolt lock nut (3) and
remove the fork center bolt (2) from the fork
damper.
Do not remove the lock nut from the fork damper
piston rod. If the lock nut is removed, the piston
rod will fall in the fork damper and you may not
reassemble the fork damper.
8. Remove the push rod (5) from the fork damper.
9. Remove the piston base (4) or mechanic’s
stopper tool between the axle holder (1) and
fork center bolt lock nut (3) while pushing the
fork outer tube.
Be careful not to damage the lock nut and fork
center bolt hole.
10. Remove the fork damper assembly (6) from
the fork assembly (7).
Remove the fork from the vise.
Remove the fork spring (8), spring seat collar
(9) and back-up ring/seat stopper (10) from the
fork damper assembly.
Do not attempt to separate the fork assembly and
drop the axle holder out from the outer tube, which
can damage the guide bushings (11).
To avoid damage, hold both the outer tube and
slider.
