Check Pinion Gear Rotation Torque
11. Check bearing preload torque with an inch pound torque wrench. The torque necessary to rotate the pinion gear should be:
-
Original Bearings-1 to 3 Nm (10 to 20 inch lbs.).
-
New Bearings-2 to 5 Nm (15 to 35 inch lbs.).
12. If rotating torque is above the desired amount, remove the pinion yoke and increase the preload shim pack thickness. Increasing the shim pack
thickness 0.025 mm (0.001 inch) will decrease the rotating torque approximately 0.9 Nm (8 inch lbs.).
13. Tighten pinion shaft nut in 6.8 Nm (5 ft. lbs.) increments until the maximum tightening or desired rotating torque is reached.
14. If the maximum tightening torque is reached prior to achieving the desired tightening torque, remove the pinion yoke and decrease the thickness of
the preload shim pack. Decreasing the shim pack thickness 0.025 mm (0.001 inch) will increase the rotating torque approximately 0.9 Nm (8 inch
lbs.).
