Inspection and Repair
Make all necessary adjustments, repairs or part
replacement.


Check damage or powdered iron sticking to the
sensor rotor.


Check play in the sensor rotor.


Check a broken tooth or indentation in the senso
r
rotor.
NOTE: If replacement is required remove the sensor
rotor from the axle shaft assembly with brake. (Refer to
the section Rear Axle).


Discard the used sensor rotor.

(Snapring, Oil seal and Bearing)

Installation
1. Install the sensor rotor and assemble it into the axle
shaft assembly with back plate. (Refer to the section

Limit mm(in)
0.023 (0.0009)

Contact surface must be within 0.023mm at the 10mm inside
position from rotor out side edge.
(Measurement; shall be measure more than 8 position at
circumferential direction.)
