NOTE: Refer to the EXPLODED VIEW if needed during this procedure.

Remove the starter (see STARTER REMOVAL AND INSTALLATION ).
Brush Holder Removal
Remove the end cover (A) and the M terminal nut (B).

Remove the brush holder (B).
Armature Inspection and Test
Inspect the armature for wear or damage from contact with the permanent magnet. If there is wear or damage, replace the armature.

Check the commutator diameter with a digital caliper or dial type caliper. If the diameter is below the service limit, replace the armature.
Commutator Diameter

Standard (New): 28.9-29.0 mm (1.138-1.142 in)

Service Limit: 28.0 mm (0.1102 in)

Measure the commutator (A) runout.
- If the commutator runout is within the service limit, check the commutator for carbon dust or brass chips between the segments.
- If the commutator runout is not within the service limit, replace the armature.
Commutator Runout

Standard (New): 0.02 mm (0.0008 in) max.

Service Limit: 0.05 mm (0.0020 in)

Use a digital caliper or dial type caliper to check the mica depth (A). If the mica depth is below the service limit, replace the armature.
Commutator Mica Depth

Standard (New): 0.50-0.90 mm (0.0197-0.0354 in)

Service Limit: 0.20 mm (0.0079 in)

Use an ohmmeter to check for continuity between the segments of the commutator. If there is an open circuit between any segments, replace the armature.

Place the armature (A) on an armature tester (B). Hold a hacksaw blade (C) on the armature core. If the blade is attracted to the core while the core is turned, the armature is shorted. Replace the armature.

Overrunning Clutch Inspection
Slide the overrunning clutch (A) along the shaft. Replace it if it does not slide smoothly.

If the starter drive gear is worn or damaged, replace the overrunning clutch assembly; the gear is not available separately. Check the condition of the idler gear and the torque converter ring gear. Replace it if the starter drive gear teeth are damaged.
Starter Brush Inspection
Measure the brush length. If it is shorter than the service limit, replace the brush holder assembly.
Brush Length

Standard (New): 15.0-16.0 mm (0.591-0.630 in)

Service Limit: 9.0 mm (0.354 in)

Starter Brush Holder Test
Check for continuity between the (+) brush holders (A) and the (-) brush holders (B). If there is continuity, replace the brush holder assembly.

Brush Spring Inspection
Insert the brush (A) into the brush holder, and bring the brush into contact with the commutator, then attach a spring scale (B) to the spring (C). Measure the spring tension at the moment the spring lifts off the brush. If it is not within the standard, replace the brush holder assembly.
Spring Tension

Standard (New): 22.3-27.3 N (2.27-2.78 kg, 5.00-6.13 lbs)

Planetary Gear Inspection
Check the planetary gears (A), the armature shaft gear (B), and the internal ring gear (C). Replace them if they are worn or damaged.

Starter Reassembly
Install the armature housing (A) and the armature (B) by aligning the slotted point (C) to the projection (D).

Pry back each brush spring with a screwdriver, then position the brush on the brush holder about halfway out of its holder. Release the spring to hold it in place.
NOTE: To seat the new brushes. Slip a strip of # 500 or #600 sandpaper, with the grit side up, between the commutator and the each brush, and smoothly turn the armature. The contact surface of the brushes will be sanded to the same contour as the commutator.
