plus (+) number, minus (-) number or zero (0) is
etched into the face of the pinion gear. This number
is the amount (in thousandths of an inch) the depth
varies from the standard depth setting of a pinion
etched with a (0). The standard setting from the cen­
terline of the ring gear to the back face of the pinion
is;
• Model 44 axle: 109.5 mm (4.312 inches) Fig. 40.
• Model 60 axle: 127 mm (5.000 inches) Fig. 40.
The standard depth provides the best teeth contact
pattern.

Compensation for depth variance is achieved by a
selected thickness oil slinger (production) or shims
(service). The slinger is placed between the inner pin­
ion bearing cone and gear head (Fig. 41). The shim
pack is placed under the inner (rear) bearing cup. To
change the pinion adjustment, shims are available in
thicknesses of 0.003, 0.005, and 0.010 inch. If
equipped, the oil slinger or baffle must be mea­
sured and the thickness included with the total
shim pack.

If a new gear set is being installed, note the
number etched into both pinion gears. Add or
subtract the thickness of original depth shims
to compensate for the difference in depth vari­
ances. Refer to the Depth Variance charts.
