collapsible spacer or bearings may result.
3. Install yoke washer and a new nut on the pinion gear and tighten the nut until there is zero bearing end-play.
4. Tighten the nut to 271 Nm (200 ft. lbs.).
CAUTION: Never loosen pinion gear nut to decrease pinion rotating torque and never exceed specified preload torque. If preload torque or
rotating torque is exceeded a new collapsible spacer must be installed.
5. Rotate the pinion gear a minimum of ten times and verify pinion rotates smoothly. Rotate pinion shaft an inch pound torque wrench. Rotating
torque should be equal to recorded reading plus an additional 0.56 Nm (5 in. lbs.) (Fig. 33).
6. If the rotating torque is low, use Spanner Wrench 6958 to hold the pinion yoke (Fig. 34), and tighten the pinion nut in 6.8 Nm (5 ft. lbs.)
increments until the proper rotating torque is achieved.
CAUTION: If maximum tightening torque is reached prior to reaching required rotating torque, the collapsible spacer may have been damaged.
Replace the collapsible spacer.
7. Install the propeller shaft with reference marks aligned.
8. Add gear lubricant to the differential if necessary.
