• Replace magnetic switch if continuity does not exist.
2.
Continuity test (between “S” terminal and “M” terminal)
• Replace magnetic switch if continuity does not exist.
PINION PROTRUSION LENGTH
• With pinion driven out by magnetic switch, push pinion back to
remove slack and measure the clearance “L” between the front
edge of the pinion and the pinion stopper.

1.
Inspect pinion teeth.
• Replace pinion if teeth are worn or damaged. (Also check con-
dition of ring gear teeth.)
2.
Inspect reduction gear teeth (If equipped).
• Replace reduction gear if teeth are worn or damaged. (Also
check condition of armature shaft gear teeth.)
3.
Check to see if pinion locks in one direction and rotates
smoothly in the opposite direction.
• Replace pinion assembly if it is locked or rotated in both direc-
tions or unusual resistance is evident.
BRUSH HOLDER ASSEMBLY
Brush
• Check wear of brush.
• Replace brush if the measurement value is less than the specified
value.
Brush Spring
• Check brush spring tension with brush spring detached from
brush.
• Replace brush spring if the measurement value is less than the
specified value.

STARTER MOTOR
1.
Perform insulation test between brush holder (positive side) and
its base (negative side).
-
Replace brush holder assembly if continuity does not exist.
2.
Check brush to see if it moves smoothly.
-
If brush holder is bent, replace it.
-
If sliding surface is dirty, clean it.
YOKE CHECK
Magnet is secured to yoke by bonding agent. Check magnet to see
that it is secured to yoke and for any cracks. Replace malfunctioning
parts as an assembly.
CAUTION:
Never clamp yoke in a vise or strike it with a hammer.
ARMATURE CHECK
1.
Continuity test (between two segments side by side)
-
Replace if continuity does not exist.
2.
Insulation test (between each commutator bar and shaft)
-
Replace if continuity exists.
3.
Check commutator surface.
-
Grind commutator with No. 500 – 600 emery paper if the surface
is rough.
