14.Check that the O-ring (12) on the fork damper
assembly (4) is in good condition. Apply the
recommended fork oil to the O-ring.
15.Pull up the outer tube (1) slowly and install
the fork damper assembly (4) into the outer
tube.

16.Insert both fork legs into the fork clamps.
Tighten the fork lower pinch bolts (13) to the
specified torque:
15 Ibf·ft (20 N·m, 2.0 kgf·m)

19.Tighten the fork lower pinch bolts (13) to the
specified torque:
15 Ibf·ft (20 N·m, 2.0 kgf·m)
20.Tighten the fork upper pinch bolts (17) to the
specified torque:
16 Ibf·ft (22 N·m, 2.2 kgf·m)
Over-tightening the pinch bolts can deform the
outer tubes. Deformed outer tubes must be
replaced.

17.Tighten the fork damper (4) to the specified
torque using the lock nut wrench (14).
Actual:
25 lbf·ft (34 N·m, 3.5 kgf·m)
Torque wrench scale reading:
23 Ibf·ft (31 N·m, 3.2 kgf·m)
, using a 20 in
(50 cm) long torque wrench.
When using the lock nut wrench, use a 20-inches
long deflecting beam type torque wrench. The
lock nut wrench increases the torque wrench’s
leverage, so the torque wrench reading will be
less than the torque actually applied to the fork
damper.

18.For ease of releasing air pressure after the
forks are installed, loosen the lower pinch
bolts and position the outer tubes so that the
pressure release screws are in front of the
rebound damping adjusters.
Align (15) the top of the outer tube (1) with
the top surface of the upper fork clamp (16).
