PINION BEARING PRELOAD
Pinion Gear Shimming Instructions
Note: This procedure is required only when replacing the front or rear pinion bearings and
races or the ring and pinion gears.
Note: To perform this procedure, all parts must be clean and the bearings lightly lubricated.
Setting the Pinion Gear Depth
This formula is used to calculate the amount of shims required to properly set the depth:
C - B - A + (DV) = Pinion Shim (mm) where,
DV
= The number on the face of the pinion gear.
A
= The distance in millimeters from the face of the pinion gear to the top of the
inner pinion bearing race (see illustration)
B
= 54.
C
= The number on the edge of the differential side plate closest to the input shaft
(see illustration, next page).
D
= The number on the edge of the differential side plate farthest from the input
shaft (see illustration, see next page).
E
= The distance in millimeters from the rear of the drive housing to the face of
the pinion gear (see illustration).
Once a shim has been selected and the pinion gear is installed, confirm that: E - D = B + (DV)
Set Pinion Bearing Preload
Note: The pinion gear depth must be set before the preload. Refer to Setting the Pinion Gear Depth.
1: Install the pinion gear, spacer, and shims into the housing.
2: Install the outer pinion bearing.
3: Install the main gear onto the pinion shaft and torque the pinion nut to 220-241 Nm (154-169 foot pounds).
4: Measure the torque required to rotate the pinion shaft in the housing.
5: The torque required to rotate the pinion shaft should be between 1.57-4.14 Nm (1.1 and 2.9 foot pounds).
If the torque is not within specifications then add or subtract from the total shim thickness and repeat this
procedure until the proper preload is obtained.
Note: Add shims to decrease torque.
This section is one section of a complete service
manual. Before starting any procedure, read all
warnings and instructions that are located in the
Service Guidelines chapter.
WARNING
DV: On face of pinion gear
