Servicing Your Honda 89
Suspension
NOTICE
Improper disposal of drained oil is harmful to the
environment.
5. Pour the recommended fork oil (page 88) into
the outer tube.
Fork Oil Capacity:
Be sure the oil capacity is the same in both fork
legs.
6. Check that the O-ring (7) on the fork damper
(2) is in good condition. Apply the
recommended fork oil to the O-ring.
Temporarily install the fork damper to the
outer tube (1).
After installing the fork leg (page 120), tighten
the fork damper to the specified torque using
the lock nut wrench:
Actual:
22 lbf·ft (30 N·m, 3.1 kgf·m)
Torque wrench scale reading:
20 lbf·ft (27 N·m, 2.8 kgf·m), using a 20 in
(50 cm) long deflecting beam type torque
wrench.
When using the lock nut wrench, use a 20 in (50
cm) long deflecting beam type torque wrench with
a lock nut 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.
