Inspection and Repair

Repair or replace necessary parts if extreme wear or
damage is found during inspection.

Armature

Measure the outer diameter of commutator, and replace
with a new one if it is out of the limit.

Standard: 30 mm (1.1811 in)

Limit: 29 mm (1.1417 in)

065RS014

Check for continuity between segment and segment on
the commutator. Replace commutator if there is no
continuity (i.e., disconnected).

065RS015

Check for continuity between commutator and shaft.
Also, check for continuity between commutator and
armature core, armature core and shaft. Replace
commutator if there is continuity (i.e., internally
grounded).

065RS016

Measure runout of the commutator with a dial gauge.
Repair or replace, if it exceeds the limit.

Limit: 0.4 mm (0.0157 in)

065RY00061

6D3–11

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).
