torque using the lock nut wrench (16).
Actual:
30 N·m (3.1 kgf·m, 22 lbf·ft)
Torque wrench scale reading:
27 N·m (2.8 kgf·m, 20 Ibf·ft), using a 50 cm
(20 in) long deflecting beam type torque
wrench.
• Lock nut wrench
(4)
When using the lock nut wrench, use a 50 cm (20
in) 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.
