XL-7 Standard 4WD V6-2.7L (2002)
Rotor: Testing and Inspection
Rotor
-
Using ohmmeter, check for continuity between slip rings of rotor. If there is no continuity, replace rotor.
Resistance between slip rings of rotor Standard: 1.6 - 2.0 Ohm at 20 °C (68 °F)
-
Using ohmmeter, check that there is no continuity between slip ring and rotor. If there is continuity, replace rotor.
-
Check slip rings for roughness or scoring. If rough or scored, replace rotor.
Using a vernier caliper, measure the slip ring diameter.
If the diameter is less than minimum, replace the rotor.
Diameter of slip ring
Standard: 14.2 - 14.4 mm (0.557 - 0.567 in.)
Diameter of slip ring
Minimum: 12.8 mm (0.504 in.)
