Differentials part p3
Limited Slip Differential
This differential lock device is totally automatic. It does not require any type of manual
operation and significantly reduces (but does not completely eliminate) wheel
The difference in speed, between the sun gears and the differential casing when a
wheel begins to slip as a result of grip loss, is impeded by clutch assemblies that are
compressed by axial thrusts from the bevel drive torque transmitted to the sun gears
of the teeth on the two planet gears.

Dog Clutch Differential Lock:
With diff lock disengaged no oil pressure is supplied, spring keeps the dog clutch
oil can return to sump.
When the diff lock switch is activated the solenoid valve opens supplying low
to the piston, overcoming the spring locking the differential.
Multi-Plate Differential Lock:
• Actuated from Low Pressure Circuit Oil - via solenoid valve.
• Terra lock control for automatic dis-engage and re-engagement.
1- Steering angle.
2- Brake operation.
3- Steering angle and speed.
4- Fast raise/lower switch position.
6 drive discs and 6 driven discs
Assemble side gears, pivot pins and retaining pins.
Place the side gear (3) complete with a test shim (2) on tool no. 293986 (1).
Assemble the side gear and attached tool no. 293986 on the differential casing, place
the crown wheel above it and fix the crown wheel with three bolts (4). Turn the
assembly to settle.
Place a dial test indicator gauge with the stylus on the tool screw (5), press the tool
and set gauge to zero.
Pull the tool (6) upwards and read the travel (H) on the gauge.
