Drive Motor Rotor: Service and Repair

IMA Motor Rotor Removal/Installation

Special Tools Required

- Rotor Puller 07YAC-PHM010C

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 IMA motor rotor.

WARNING
If the rotor is installed by hand, it may suddenly be pulled toward the stator with great force, causing serious hand or finger injury. Always use the special tool (rotor puller) to remove or install the rotor assembly.
- Keep the motor rotor away from magnetically sensitive devices.
- Do not blow air near the rotor, as metal particles may get on the magnets.
- Store the rotor in the designated storage box, and keep it away from sensitive devices during storage.


1. Remove the transmission CVT Transmission Removal.

2. Remove the support (A).






3. Remove the drive plate (A).






4. Turn the ignition switch to LOCK (0). Turn the battery module switch OFF. Slide the protector (A) in the direction of the arrow. Push the tab (B), then raise the lever (C). Remove the IMA motor power cable (D) from the motor stator.

NOTE:

- If the IMA motor power cable connector is dirty, clean it before removal.
- Cover the disconnected connector (E) with a plastic bag (F), and wrap IMA motor power cable terminals with insulating tape (G).
- If the IMA motor power cable is wet, dry it with a clean shop towel before you wrap it with tape. Do not use compressed air.





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






6. Remove three of the six bolts (A) as shown.






7. Install the rotor puller guide pins, then remove the remaining three bolts (A).






8. Attach the rotor puller with its supplied bolts.

NOTE: When installing the rotor puller, position the puller to fit over the guide pins (A).






9. Remove the IMA motor rotor (A).






10. To prevent damage to the rotor magnets while working on the stator, place the rotor, with puller attached, into the puller case.






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

NOTE:

- When installing the rotor, install the special tool to the rotor and set the rotor with the tool tip stretched out.
- 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.





12. Remove the plastic film.

13. Reconnect the IMA motor power cable to the motor stator.

14. Reinstall the drive plate.

15. Reinstall the support.

16. Install the transmission CVT Transmission Installation.

17. Do the motor rotor position calibration procedure.
