Measure pinion torque to rotating (1) with an inch pound torque wrench (2). With a torque wrench set at 542 N.m (400 ft. lbs.) tighten nut in 6.8 N.m (5 ft. lbs.) increments until pinion torque to rotating is achieved. Pinion torque to rotating is, the recorded reading plus an additional 0.56 N.m (5 in. lbs.).
CAUTION:
If maximum tightening torque of 542 N.m (400 ft. lbs.) is reached before torque to rotate is achieved, the collapsible spacer may have been damaged. Never loosen pinion gear nut to decrease pinion gear bearing rotating torque and never exceed specified preload torque. Failure to follow these instruction may result in damage.
