Toyota Venza: Inspection

(a) Hold the generator rotor using SST, and turn the clutch pulley clockwise to check that the outer ring locks.

SST: 09820-63021

If the result is not as specified, replace the clutch pulley.

(a) Check that the bearing is not rough or worn.

OK:

The bearing rotates smoothly.

If the bearing does not rotate smoothly, replace the bearing.

(a) Using a vernier caliper, measure the length of the exposed brushes.

Standard exposed brush length:

9.5 to 11.5 mm (0.375 to 0.452 in.)

Minimum exposed brush length:

4.5 mm (0.178 in.)

If the exposed brush length is less than the minimum, replace the brush holder assembly.

(a) Check that the generator rotor bearing is not rough or worn.

If necessary, replace the generator rotor assembly.

(b) Check the generator rotor for an open circuit.

(1) Using an ohmmeter, measure the resistance between the slip rings.

Standard Resistance:

If the result is not as specified, replace the generator rotor assembly.

(c) Check the rotor for a short to ground.

(1) Using an ohmmeter, measure the resistance between the slip ring and rotor.

Standard Resistance:

If the result is not as specified, replace the generator rotor assembly.

(d) Using a vernier caliper, measure the slip ring diameter.

Standard diameter:

14.2 to 14.4 mm (0.560 to 0.566 in.)

Minimum diameter:

14.0 mm (0.552 in.)

If the diameter is less than the minimum, replace the generator rotor assembly.
