IMA Motor Removal/Installation

Special Tools Required

Rotor puller (Available for loan or purchase from AHM Special Tools) 07YAC-PHM010B

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 keep it away from sensitive devices during storage.
Do not blow air near the rotor, as the metal particles may get on the magnet.

M/T model: Remove the transmission (see TRANSMISSION REMOVAL ) and the clutch (see CLUTCH ).
CVT model: Remove the transmission (see TRANSMISSION REMOVAL ).
Remove the stator cover (A).

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 cover, and be sure to apply the liquid gasket, P/N 08718-0009, to the mating surfaces just before installation.

Install the IMA motor in the reverse order of removal.
NOTE:
- Install the commutation sensors properly. Do not set sensors A, B, and C in the wrong positions.
- Connect the motor power cable with the U phase, V phase, and W phase set in the correct positions.
- Clean the surfaces before applying liquid gasket, P/N 08718-0009.
- 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.
