Chapter 3 - Drive System: Drive Shafts and Differentials

5d. The four pins on the differential lock collar

extend through the differential side plate
when the lock is engaged. This locks the
16-tooth bevel gear to the differential side
plate. See Figure 3.83.

The 16-tooth miter gear that resides in the side
plate of the differential is splined: it transfers
drive torque to the right-side axle.

Locking one miter gear effectively locks the
whole miter gear set, preventing the wheels from
rotating forward or back in relation to one-
another. The rear wheels are forced to rotate at
the same speed.

5e. The large side of the differential body con-

tains a set of four 10-tooth miter gears.
They are located in a central block by
three cross-pins: One long pin and two
short pins. See Figure 3.84.

5f. With the block and cross-pins removed, the

four 10-tooth meter gears can be lifted-out
of the differential body. See Figure 3.85.

Thrust washers are located between each 10-
tooth miter gear and the differential body.

The 16-tooth miter gear that resides in the base
of the differential body is splined: it transfers
drive torque to the left-side axle.

On assembly, the shims will generally be placed
back in their original locations. If the order has
been lost, it will be necessary to re-establish
proper alignment between the pinion gear and
the ring gear. See Figure 3.86.

The center-line of the pinion gear does not align
with the centerline of the ring gear.
