Toyota Venza: Inspection

(a) Hold the center of the pulley, and confirm that the outer ring turns counterclockwise and does not turn clockwise.

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

(a) Check that the bearing is not rough or worn and that it rotates smoothly.

OK:

The bearing rotates smoothly.

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

(a) Using a vernier caliper, measure the brush length.

Standard length:

9.5 to 11.5 mm (0.374 to 0.453 in.)

Minimum length:

4.5 mm (0.177 in.)

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

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

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

(b) Check the rotor for an open circuit.

(1) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

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

(c) Check if the rotor is grounded.

(1) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

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

(1) Using a vernier caliper, measure the diameter of each slip ring.

Standard diameter:

14.2 to 14.4 mm (0.559 to 0.567 in.)

Minimum diameter:

14 mm (0.551 in.)

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