IMA Motor Rotor Removal And Installation

Service Information

IMA Motor Rotor Removal and Installation





Removal

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. CVT transmission CVT Transmission Removal And Installation

1. Remove the CVT transmission assembly.

2. Drive Plate Assembly





1. Remove the flywheel support (A) and the drive plate (B).

2. Inspect the drive plate and the flywheel support, and replace it if it is damaged.

3. IMA Motor Rotor





1. Tape together end to end two plastic sheets (300 long by 200 wide by 0.2 mm thick) and install them between the IMA motor rotor (B) and motor stator (C) to protect them during removal.





2. Remove three of the six bolts as shown.





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





4. Attach the rotor puller with it's supplied bolts.

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





5. Turn the handle of rotor puller.

6. Remove the IMA motor rotor (A).





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

1. IMA Motor Rotor





1. Attach the rotor puller on the IMA motor rotor.

2. Tape together end to end two plastic sheets (300 long by 200 wide by 0.2 mm thick) and install them around the outside of the rotor.

3. Install the IMA motor rotor to the motor stator.

NOTE:
* Before installing the rotor, make sure the handle of rotor puller is fully turned in clockwise.
* Slowly turn the handle of the rotor puller counterclockwise to insert the rotor into the stator. The rotor is drawn into the stator by magnetic force.

4. Slowly turn the handle of the rotor puller to lower and install IMA motor rotor into the motor stator.





5. Remove the rotor puller.





6. Remove the rotor puller guide pins (A), then install the remaining three bolts (B).





7. Install three of the six bolts as shown.

8. Remove the plastic film (A).

2. Drive Plate Assembly





1. Install the drive plate (A) and the flywheel support (B) on the motor rotor (C), and tighten the bolts to the specified torque in a crisscross pattern in at least two or three steps.
