2. Continuity test (between ``S'' terminal and ``M'' terminal).
+No continuity ... Replace.
PINION/CLUTCH CHECK
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.
+If it locks or rotates in both directions, or unusual resistance is
evident. ... Replace.
BRUSH CHECK
Brush
Check wear of brush.
Wear limit length:
Refer to SDS (EL-51).
+Excessive wear ... Replace.
Brush spring pressure
Check brush spring pressure with brush spring detached from
brush.
Spring pressure (with new brush):
Refer to SDS (EL-51).
+Not within the speci®ed values ... Replace.
Brush holder
1. Perform insulation test between brush holder (positive side)
and its base (negative side).
+Continuity exists. ... Replace.
2. Check brush to see if it moves smoothly.
+If brush holder is bent, replace it; if sliding surface is dirty, clean.

5. Check depth of insulating mold from commutator surface.
+Less than 0.2 mm (0.008 in) ... Undercut to 0.5 to 0.8 mm
(0.020 to 0.031 in)
Assembly
Apply high-temperature grease to lubricate the bearing, gears and
frictional surface when assembling the starter.
Carefully observe the following instructions.
PINION PROTRUSION LENGTH ADJUSTMENT
Clearance ``!''
With pinion driven out by magnetic switch, push pinion back to
remove slack and measure clearance ``!'' between the front edge
of the pinion and the pinion stopper.
Clearance ``!'':
Refer to SDS (EL-51).
Movement ``!''
Compare movement ``!'' in height of pinion when it is pushed out
with magnetic switch energized and when it is pulled out by hand
until it touches stopper.
Movement ``!'':
Refer to SDS (EL-51).

RING FITTING IN REAR BEARING
+Fix ring into groove in rear bearing so that it is as close to the
adjacent area as possible.
CAUTION:
Do not reuse rear bearing after removal.
REAR COVER INSTALLATION
1. Fit brush assembly, diode assembly, regulator assembly and
stator.
2. Push brushes up with ®ngers and install them to rotor.
Take care not to damage slip ring sliding surface.
