17.Tighten the fork damper (4) to the specified
torque using the lock nut wrench (14).
Actual:
34 N·m (3.5 kgf·m, 25 lbf·ft)
Torque wrench scale reading:
31 N·m (3.2 kgf·m, 23 lbf·ft), using a 50 cm
(20 in) long torque wrench.
When using the lock nut wrench, use a 20-inch
long deflecting been 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.
