4) Inspection of Starter Motor Pinion

1. Check pinion teeth for crack and wear. Replace if necessary.

2. Fix clutch 2, and turn only pinion 1 to check that it can be

rotated smoothly in one direction. Replace if necessary.

5) Inspection of Armature

1. Check commutator 1 for dirt. If necessary, clean by using

sand paper of No. 600 or by air-blowing.

2. Measure commutator 1 outer diameter. Replace starter

motor ass'y if outer diameter is less than specified value.

Turn pinion 1 counterclockwise to check that it

can be rotated smoothly. Also, check that pinion

is locked when turned clockwise.

Commutator Outer Diameter : Standard Value

30.0 mm ( 1.181 in )

Wear Limit :

29.50 mm ( 1.142 in )

Armature Conductivity :

b Between Commutator Segments 3 - 3

Conductive

c Between Segment - Armature Core

Non-conductive

d Between Segment - Armature Shaft

Non-conductive

4. Check electrical conductivity of armature 2. Replace starter

motor ass'y if other than specified condition.

3. Measure undercut a of commutator 1. Replace starter

motor ass'y if less than specified value.

Commutator Undercut : Standard Value

0.5 to 0.8 mm ( 0.020 to 0.031 in )

Wear Limit a :

0.2 mm ( 0.008 in )
