NOTE: When using a torque wrench other than ST4, use the calculation below to calculate and tighten the lock nut.
Tighten using the ST and the straight line torque wrench.
T = L1/(0.1 + L1) x 285

T	N.m (kgf-m, ft-lb)	Torque wrench setting
L1	m (in)	Torque wrench length
0.1 m (3.94 in)		Length of ST
285 N.m (29.0 kgf-m, 210 ft-lb)		Tightening torque (lock nut)

Measure the starting torque. Refer to MANUAL TRANSMISSION AND DIFFERENTIAL(6MT) (TY85)>DRIVE PINION SHAFT ASSEMBLY>INSPECTION .
Using the ST, crimp the lock nut in 2 locations, with dimensions within A 37±0.5 mm (1.46±0.02 in).
