[8] Torque wrench reading =
[9]
19 Torque wrench effective length [m (ft)] x Specified torque [N . m (kgf . m, lbf . ft)]
[9] Torque wrench effective length [m (ft)] + 0.05 [m (0.164 ft)]
20
TORQUE: 64 N . m (6.5 kgf . m, 47 lbf . ft)
• Example:
Torque wrench reading in case of using a torque wrench
which effective length is 0.4 m (1.31 ft)
0.4 [m (1.31 ft)] x 64 [N . m (6.5 kgf . m, 47 lbf . ft)]
0.4 [m (1.31 ft)] + 0.05 [m (0.164 ft)]
= 57 [N . m (5.8 kgf . m, 42 lbf . ft)]
40) Remove the piston rod/outer tube assembly from the vise,
and wipe up the excess of the thread locking agent.
