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.

Remove the transmission.
- M/T model (see NEUTRAL POSITION SWITCH REPLACEMENT )
- CVT model (see TRANSMISSION REMOVAL )
M/T model: Remove the clutch (see CLUTCH REPLACEMENT ).
M/T model: Remove the flywheel (see CLUTCH REPLACEMENT ).
CVT model: Remove the drive plate (see DRIVE PLATE REMOVAL/INSTALLATION ).
Install a plastic film (A) between the IMA motor rotor (B) and the motor stator (C).

Install the parts in the reverse order of removal.
NOTE:
- When installing the rotor, make sure the special tool is attached with its handle turned out several threads.
- 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.
