Transfer Box Motor Position For High/Low Range Mode
| Item Number | Description |
|---|---|
| 1 | Motor shaft |
| 2 | Solenoid shift fork |
| 3 | Solenoid |
| 4 | Shifting sleeve |
| 5 | Actuation cam |
To actuate the high/low range change, the transfer box control module de-energizes the solenoid (3). A spring in the solenoid retracts the solenoid pin and rotates the solenoid shift fork (2). This engages the shifting sleeve (4) to the dogteeth on the high/low actuation cam (5). The rotational movement of the motor shaft (1) is then linked to the cam.
In this position, the multi-plate clutch is open, the differential cannot be locked and torque cannot be biased. Once the range change is complete the system returns to clutch control mode. In the event of an electrical failure, the motor will default to this position.
