STARTING AND CHARGING SYSTEM (6VE1 3.5L)
Polish the commutator surface with sandpaper #500 to
#600 if it is rough.
065RW012
Measure the depth of insulator in commutator. Replace, if
it is below the limit.
Standard: 0.45 mm to 0.75 mm (0.0177 in to
0.0295 in)
Limit: 0.2 mm (0.008 in)

Brush
Measure the length of brush.
Replace with a new one, if it is below the limit.
Standard: 15 mm (0.5906 in)
Limit: 11 mm (0.43 in)
065RW014
Brush Holder
Check for continuity between brush holder (+) (4) and
base (–). Replace, if there is continuity (i.e., insulation is
broken).

Brush Spring
Use spring balancer to measure the spring setting force
when remove the spring from the brush.
Standard: 17.65–23.54 N (38.9–51.9 lb)
Limit: 11.77 N (25.9 lb)
Magnetic Switch
Temporarilly connect the magnetic switch between the
overrunning clutch and housing.
Perform the steps described below in 3 to 5 seconds.
1. Pull in test
Connect the ground (–) to terminal C and magnetic
switch body.
Verify that the pinion pulls out when the battery (+)
pole is connected to terminal 50.
065R100017
2. Hold in test
Observe that the pinion stays when the lead wire is
disconnected from terminal C.
065R100018
3. Return test
Connect the ground (–) to terminal 50 and magnetic
switch body.
Verify that the pinion pulls out when the battery (+)
pole is connected to terminal C and the pinion pulls
away when the lead wire is disconnected from
terminal 50.
065R100019
Field Coil
1. Check for continuity between the end of the field coil
and yoke body.
Replace the field coil, if there is continuity.

2. Check continuity between the lead wire of terminal C
and brush.
Replace the yoke assembly, if there is no continuity.
065RY00066
Overrunning Clutch
1. Visual check for excessive wear or damage.
2. Test the pinion rotation, it must rotate smoothly when
rotated clockwise and it shouldn’t rotate when turned
counterclockwise.
065RY00067
Bearing
1. Inspect excessive wear or damage.
Replace the bearing if an abnormal noise is heard
under normal operating condition.
