STARTER MOTOR PARTS CLEANING

(1) Do not immerse parts in cleaning solvent. Immersing the

yoke and field coil assembly and/or armature will damage
insulation. Wipe motor assembly with a cloth only.

(2) Do not immerse drive unit in cleaning solvent. Overrunning

clutch is pre-lubricated at the factory and solvent will wash
lubrication from clutch.

the runout with a dial indicator.

Standard value: 0.05 mm

Limit: 0.1 mm

OVERRUNING CLUTCH CHECK

(1) While holding clutch housing, rotate the pinion. Drive

pinion should rotate smoothly in one direction, but should
not rotate in opposite direction. If clutch does not function
properly, replace overrunnig clutch assembly.

(2) Inspect pinion for wear or burrs. If pinion is worn or burred,

replace overrunning clutch assembly. If pinion is damaged,
also inspect ring gear for wear or burrs.

FRONT AND REAR BRACKET BUSHING CHECK

Inspect bushing for wear or burrs. If bushing is worn or burred,
replace front bracket assembly or rear bracket assembly.

BRUSH AND SPRING REPLACEMENT

(1) Brushes that are worn beyond wear limit line, or oil-soaked,

should be replaced.

(2) When replacing ground brush, slide the brush from brush

holder by prying retaining spring back.

ARMATURE TEST

ARMATURE COIL SHORT-CIRCUIT TEST

(1) Place armature in a growler.
(2) Hold a thin steel blade parallel and just above while rotating

armature slowly in growler. A shorted armature will cause
blade to vibrate and be attracted to the core. Replace
shorted armature.

ARMATURE COIL EARTH TEST

Check the insulation between each commutator segment and
armature coil core.
If there is no continuity, the insulation is in order.
