Differential Lock Clutch Disengaged
When the switch is in the disengaged position (middle) and a brake pedal is pushed, the solenoid will be de-
energized. Regulated pressure will be at the valve cartridge. The piston of the differential lock clutch is
mechanically returned to the neutral position. As the piston retracts, oil will be ported to the transmission housing
and the differential lock clutch will disengage
NOTE: It is not possible to disengage the differential lock with the switch control. Pushing either brake pedal will
deactivate the differential lock.
The differential lock switch has three (3) positions. The mid switch position is OFF when the differential lock is
deactivated. The same switch position is ON when the differential lock is activated manually.
