Drive Motor/Generator: Service and Repair

IMA Motor Removal/Installation

Special Tools Required
Rotor puller (Available for loan from AHM Special Tools) 07YAC-PHM010A

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.
^ Do not use the rotor motor if the fiberglass band is damaged. If the band breaks during use, magnets may come loose from the motor rotor.
^ Keep the motor rotor away from magnetically sensitive devices.
^ Store the rotor in the designated storage box and hold it away from the sensitive device during storage.
^ Do not blow air near the rotor, as the metal particles get on the magnet.

1. Remove the transmission on vehicle with M/T, the clutch on vehicle with M/T. and the transmission on vehicle with CVT.





2. Remove the stator cover (A).





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





4. Install the guide pins (A), then remove the remaining three bolts (B).





5. Attach the rotor puller with the bolts supplied.





6. Remove the motor rotor (A).





7. Remove the bolts (A).





8. Remove the motor stator (A).

NOTE: Clean the mating surfaces of the housing assembly and block, and apply the liquid gasket, P/N 08718-0009, to the mating surfaces.





9. Remove the cover (A) and motor power cables (B).

NOTE:
^ Check the position of the U phase, V phase and W phase before disconnecting the motor power cable.
^ Clean the mating surfaces of the housing assembly and block, and be sure to apply the liquid gasket, P/N 08718-0009, to the mating surfaces just before installation.





10. Remove the motor commutation sensor A (A), sensor B (B) and sensor C (C).





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

NOTE:
^ Install the commutation sensors properly. Do not set the sensor A, B and C in the wrong position.
^ Connect the motor power cable with the U phase, V phase, and W phase set in the correct positions.
^ Clean the surfaces where the liquid gasket, P/N 08718-0009, is applied.
^ Set the rotor on the special tool, and install the rotor with the end of the special tool extended.
^ 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.
