(8) Install a differential bearing on each hub with
Installer C-4213 and Handle C-4171.
PINION DEPTH MEASUREMENT AND ADJUSTMENT
Pinion measurement are taken with C-758-D6 Tool
Set (Fig. 19) with pinion bearing cups installed.

Fig. 19 9 1/4 Axle Pinion Adjustment Toois
(1) Install front (outer) bearing cup with Tool Set
C-4306 and Handle C-4171.
(2) Install rear (inner) bearing cup with Tool Set
C-4306 and Handle C-4171.
• Position Spacer (SP-6017) over Shaft (SP-526)
• Position pinion rear bearing on shaft
• Position tools (with bearing) in the housing
• Install Sleeve (SP-1730)
• Install pinion front bearing
• Install Spacer (SP-6022)
• Install Sleeve (SP-535-A), Washer (SP-534) and
Nut (SP-533)
(3) Tighten the nut to seat the pinion bearings in
the housing. Allow the sleeve to turn several times
during the tightening to prevent brinelling the bear­
ing cups or the bearings.
Depth shim(s) are positioned between the pin­
ion gear rear bearing and pinion gear to pro­
vide the separation distance. The required
thickness of the depth shim(s) is determined ac­
cording to the following information.
(4) Loosen the compression nut tool. Lubricate the
pinion gear front and rear bearings with gear lubri­
cant. Re-tighten the compression nut tool to 1-3 N-m
(15-25 in. lbs.) torque. Rotate the pinion gear several
complete revolutions to align the bearing rollers.
• Install Gauge Block SP-6020 at the end of SP-526
• Install Cap Screw (SP-536) and tighten with
Wrench SP-531 (Fig. 20).
(5) Position Crossbore Arbor SP-6018 in the differ­
ential housing.
(6) Center the tool and place a piece of 0.002 inch
shim stock at each end of the arbor. Position the
Fig. 20 Gauge Block
bearing caps on the arbor tool. Install the attaching
bolts. Tighten the cap bolts to 14 N-m (10 ft. lbs.)
torque.
(7) Trial fit depth shim(s) between the crossbore
arbor and gauge block (Fig. 21). The depth shim(s)
fit must be snug but not tight (drag friction of a
feeler gauge blade).
Fig. 21 Depth Shim(s) Selection
Depth shims are available in 0.001-inch incre­
ments from 0.020 inch to 0.038 inch.
(8) Note the etched number on the face of the drive
pinion gear (e.g., -0, -1, -2, +1, +2, etc.). The numbers
represent thousands-of-an-inch deviation from the
standard. If the number is - (negative) add that value
to the required thickness of the depth shim(s). If the
number is + (positive) subtract that value from the
thickness of the depth shim(s). If the number is 0 no
change is necessary.
(9) Remove the tools from the differential housing.
(10) Position depth shim(s) on pinion gear shaft
and install rear bearing with Installer C-3095A (Fig.
22).
