DIFFERENTIAL

M-40prose procedure

Standard differential vs Viscous L.S.D. differential - replacement is by assembly for L.S.D.

1
Check the backlash of the side gears and pinion gears. Adjust by inserting the proper thickness thrust washer at both sides. (Standard) If not within specification, replace the differential gear as an assembly. (Viscous L.S.D.)
Standard backlash: 0—0.1mm (0—0.004 in)

2
Install the knock pin to secure the pinion shaft. Stake the pin with a punch to prevent it from coming out of the case.

Thickness1.95—2.00mm (0.0768—0.0787 in)

Thickness2.05—2.10mm (0.0807—0.0827 in)

Thickness2.15—2.20mm (0.0846—0.0866 in)

Adjustment of drive pinion and ring gear backlash

NOTE

Apply approx. 0.04 cc (0.0024 cu in) of thread-locking compound at each point.

1
Apply thread-locking compound to the bolt threads (A) and point (B) of the gear back face.

2
Install the ring gear onto the gear case.
Tightening torque: 69—83 N·m (7.0—8.5 m-kg, 51—61 ft-lb)
3
Press the bearing inner races (side bearing) on with the SST.

4
Install the differential gear assembly in the carrier.
5
Note the identification marks on the adjusting nuts, and install them on their respective sides.
6
Install the differential bearing caps, making sure that the identification mark on the cap corresponds with the one on the carrier with the SST.
