Important: When replacing the encoder rotary position sensor, follow steps (6-10). The rotary position sensor is circular with 3 contacts on one
side and is positioned behind the motor/encoder baseplate/gasket. The rotary position sensor replacement kit consists of a rotary position sensor,
baseplate/gasket, and detailed instruction sheet.
7. Release the 4 tabs that retain the motor/encoder plastic baseplate and remove the baseplate/gasket (1).
8. Discard the old baseplate/gasket, replacement baseplate/gasket provided in rotary position sensor kit.
9. Gently lift the motor/encoder rotary position sensor (2) from the motor shaft.
Important: The motor/encoder rotary position sensor internal wires go to a connector within the motor housing. This internal wire connector
does not have a locking tab and is easily disturbed.
10. Disconnect the rotary position sensor (2) from the wiring harness.
Important: Look at the motor/encoder housing (1) where the rotary position sensor was removed from. Take note of the "Hex" in the housing
where the new sensor will seat when properly installed.
Installation Procedure
1. Connect the wiring harness to the rotary position sensor.
Important: Provided the rotary position sensor was removed, follow steps (1-5) to install the sensor, otherwise proceed to step 6 installing the
motor/encoder to the transfer case.
2. Gently insert a suitable tool along side the internal wires and press down on the internal wire connector to ensure the connector is fully installed.
