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 (see TRANSMISSION REMOVAL ).
