7. Measure torque to rotate the pinion with an inch-

pound torque wrench. Torque measurements should

be taken every fourth (4th) revolution and should

read between 20-40 in. lbs. (2.3-4.5 N•m) of bearing

preload.

Note: If bearing preload does not fall within allowed limits,

preload can be increased by using a thinner spacer and

decreased by using a thicker spacer.

Pinion bearing preload spacers are available in the

following thicknesses 27.44-28.00 mm.
Always measure each spacer before assembly to

ensure correct thickness.

8. Repeat process until torque to rotate is between

20-40 in. lbs. (2.3-4.5 N•m). After proper preload is

achieved, remove yoke and install new seal with

proper service tool.

Do not use any silicone or permatex-type bore sealant with
this seal.

9. Remove the new seal from its package and install

with the proper driver:

R-Pinion-Use drive #126917 only

Due to the resiliency of the plastic driver, hammer rebound
may occur when the seal is seated. Keep clear of the ham-
mer rebound path!

10. Handle the seal by its outside diameter avoiding any

contact with the seal lips. During installation, use the

proper driver to make sure that the seal is mounted

properly.

11. Use a rubber mallet to drive the seal tool in until the

flange bottoms on the housing cover bore face. The

flange will locate the seal at the proper depth.

12. Install end yoke.

Note: Spicer recommends that new torque prevailing

nuts be used.

13. Use torque multiplier and torque pinion nut to

625-753 lbs. ft. (847-1021 N•m).
