(3) Commutator Segments

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 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.
