When servicing the 3WD traction motor, use a clean work space
with a non-metal surface. The motor rotor includes very powerful
magnets that can cause the rotor to move unexpectedly if working
on a metal surface. Also, any metallic debris that gets attracted to
the rotor can damage the motor after assembly.
Refer toFigure 107 for this procedure.

components or complete 3WD traction motor assembly if necessary.
