Drive Motor/Generator: Service and Repair

IMA Motor Rotor Removal/Installation
Special Tools Required
Rotor puller (Available for loan from AHM Special Tools) 07AAF-RCJA100

The motor rotor contains very strong magnets and should be handled with special care. People with pacemakers or other sensitive medical devices should not handle the motor rotor.

WARNING: If the motor rotor is installed by hand, it may suddenly be pulled toward the motor stator with great force causing serious hand or finger injury.

Always use the special tool to remove or install a motor rotor.
^ Keep the motor rotor away from magnetically sensitive devices.
^ Do not blow air near the rotor, as metal particles may get on the magnet.
^ Store the rotor in the designated storage box and hold it away from the sensitive device during storage.

1. Remove the transmission.
2. Remove the drive plate and torque converter support hub.
3. Push the tabs (A), then raise the lever (B). Remove the motor power cable (C) from the motor stator.

NOTE:
^ If the motor power cable connector is dirty, clean it.
^ Cover the disconnect connector (D) with plastic bag (E), and wrap motor power cable terminal with tape (F).
^ If the motor power cable is wet, wait until it dry.





4. Install a plastic film (A) between the motor rotor (B) and motor stator (C).





5. Remove four of the eight bolts (A) as shown.





6. Install the rotor puller guide pins, then remove the remaining four bolts (A).





7. Attach the rotor puller with the bolts supplied.





8. Remove the motor rotor (A).





9. Install the parts in the reverse order of removal.

NOTE: Turn the handle of the special tool slowly when inserting the rotor into the stator. The rotor is drawn into the stator by magnetic force.





10. Remove the plastic film.
11. Reconnect the motor power cable to the motor stator.
12. Install the drive plate and torque converter support hub.
13. Install the transmission.
14. Do the MOTOR ROTOR POSITION CALIBRATION.
