Fork Disassembly
Remove the fork as described in Fork Oil Change (pages
75 – 77).
Clean the fork assembly, especially the sliding surface
of the slider and bottom of the slider around the center
bolt before disassembling the fork.
CAUTION:
• Be careful not to scratch the slider and not to dam-
age the dust seal.
Measure the length between the axle holder and outer
tube and record it before disassembling the fork.
(1) LENGTH
Hold the outer tube, remove the fork damper from the
outer tube using a special tool and slide the outer tube
down to the dust seal on the axle holder.

(2) OUTER TUBE
Pour the fork oil from the outer tube.
Pour the fork oil from the oil hole of the fork damper.
(1) OUTER TUBE (2) OIL HOLE
Temporarily install the fork damper to the outer tube.
Set the lower end (axle holder) of the slider in a vise
with a piece of wood or soft jaws to avoid to damage.
CAUTION:
• Do not overtighten the axle holder.
Loosen the center bolt.
(1) CENTER BOLT (2) AXLE HOLDER
