8. Drain the fork oil from the outer tube (6).
Empty the fork oil from the outer tube by
pumping the outer tube several times.
9. Drain the fork oil by turning the outer tube (6)
upside down. (About 0.2 US oz (7 cm
3
) of fork
oil will be left in the outer tube when it is left
inverted for about 20 minutes at 68°F/20°C.)
Pour the drained oil into a suitable container and
dispose of it in an approved manner (page 158)
NOTICE
Improper disposal of drained oil is harmful to the
environment.
10. Pour the recommended fork oil (page 91) into
the outer tube (6).
Left Fork Outer Tube Oil Capacity:
Approximately 0.2 US oz (7 cm
3
) of fork oil
remains after draining.
This amount must be noted when filling to the
standard, maximum or minimum oil capacity.
11. Check that the O-ring (12) on the air cylinder
unit (7) is in good condition. Apply the
recommended fork oil to the O-ring.
Temporarily install the air cylinder unit to the
outer tube (6).
After installing the fork leg (page 107), tighten
the air cylinder unit to the specified torque
using a lock nut wrench:
Actual:
56 lbf·ft (76 N·m, 7.7 kgf·m)
Torque wrench scale reading:
51 lbf·ft (69 N·m, 7.0 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.
