Armature Inspection and Test

Commutator Diameter
Standard (New): 28.0

28.1 mm (1.102

1.106 in.)

Service Limit:

27.5 mm (1.083 in.)

Commutator Runout
Standard (New): 0.02 mm (0.0008 in.) max.
Service Limit:

0.05 mm (0.002 in.)

1. Remove the starter (see page 4-10).

2. Disassemble the starter as shown at the beginning

of this procedure.

3. Inspect the armature for wear or damage from

contact with the permanent magnet. If there is wear
or damage, replace the armature.

4. Check the commutator (A) surface. If the surface is

dirty or burnt, resurface it with an emery cloth or a
lathe to the specifications in step 5, or recondition
with

500 or

600 sandpaper (B).

5. Check the commutator diameter. If the diameter is

below the service limit, replace the armature.

6. 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 Mica Depth
Standard (New): 0.40

0.020 in.)

Service Limit:

0.15 mm (0.006 in.)

7. Check the mica depth (A). If the mica is too high (B),

undercut the mica with a hacksaw blade to the
proper depth. Cut away all the mica (C) between
the commutator segments. The undercut should
not be too shallow, too narrow, or V-shaped (D).

8. Use an ohmmeter to check for continuity between

the segments of the commutator. If there is an
open circuit between any of the segments, replace
the armature.

9. 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 or vibrates while
the core is turned, the armature is shorted. Replace
the armature.

10. Use an ohmmeter check for continuity between the

commutator (A) and the armature coil core (B), and
the between the commutator and the armature
shaft (C). If there is continuity, replace the armature.

11. Measure the brush length. If it is shorter than the

service limit, replace the brush holder assembly.

12. Check for continuity between the (

) brushes (A)

and the (

) brushes (B). If there is continuity,

replace the brush holder assembly.

13. Check the planetary gears (A) and the internal ring

gear (B). Replace them if they are worn or damaged.
