| Item Number | Description |
|---|---|
| 1 | Clutch piston |
| 2 | Motor shaft |
| 3 | Clutch control disc |
| 4 | Motor levers |
| 5 | Ramp mechanism balls |
By turning the clutch control disc (3), via the motor shaft (2), the motor levers (4) are rotated relative to each other. This relative movement acts on 5 balls (5) in a ramp mechanism between the two levers and give a defined axial movement. The movement forces the clutch piston (1) to induce friction between the plates supported by the clutch hub and the plates supported by the clutch basket on the differential carrier. This frictional force inhibits the differential rotation; the differential carrier and front differential side gear are locked together.
