Servomotor with reduction gear
The position-regulated servomotor with reduction gear is activated directly by the power electronics of the regulated differential lock control unit with pulse-width-modulated vehicle voltage. For determining the respective position and direction of rotation of the servomotor, this is equipped 2 hall effect sensors. There is a temperature sensor installed on the circuit board of the servomotor. For excessive temperatures on the servomotor (above 160° Celsius), the regulated differential lock (GHAS) is switched off.

NOTE:
Oil leakage possible when removing the servomotor!
When replacing the servomotor, a small amount of oil can escape. In relation to the entire amount of oil in the rear axle final drive, this amount of oil is so small that topping up final drive oil is not required.
