CHARGING SYSTEM 6D3 – 11
ROTOR
1. Check the rotor slip ring surfaces for contamination and
roughness. If rough, polish with #500-600 sandpaper.
2. Measure the slip ring diameter, and replace if it
exceeds the limit.
mm (in)
Standard Limit
34.6 (1.36) 33.6 (1.32)
3. Check for continuity between slip rings, and replace if
there is no continuity.
4. Check for continuity between slip ring and rotor core or
slip ring and rotor shaft.
In case of continuity, replace the rotor assembly.
Rear Ball Bearing
Check to see if the ball bearing rotates smoothly with no
noises.
When it does not rotate smoothly or any noises are heard,
replace it with a new one.
When installing the bearing, press it in with the stopper ring
turned to the spline side, while pushing the bearing inner ring.
Bearing press-in measurement: L mm (in)
Standard 41.8 - 42.0 (1.64 - 1.65)
STATOR COIL
1. Check for continuity between respective phases.
In case of no continuity, replace the stator.
