Magnetic Switch Check
IBefore starting to check, disconnect battery ground cable.
IDisconnect ªMº terminal of starter motor.
1. Continuity test (between ªSº terminal and switch body).
INo continuity ... Replace.
2. Continuity test (between ªSº terminal and ªMº terminal).
INo continuity ... Replace.
Pinion/Clutch Check
1. Check to see if pinion locks in one direction and rotates
smoothly in the opposite direction.
IIf it does not lock (or locks) in either direction or unusual
resistance is evident ... Replace.
2. Check pinion movement
IIf it is hard to move, apply grease or, if necessary, replace.

4. Inspect pinion teeth.
IReplace pinion if teeth are worn or damaged. (Also check
condition of ring gear teeth.)
5. Inspect reduction gear teeth.
IReplace reduction gear if teeth are worn of damaged.
(Also check condition of armature shaft gear teeth.)
Brush Check
BRUSH
Check wear of brush.
Wear limit length:
Refer to SDS (SC-30).
IExcessive wear ... Replace.
BRUSH HOLDER
1. Perform insulation test between brush holder (positive side)
and its base (negative side).
IContinuity exists ... Replace.
2. Check brush to see if it moves smoothly.
IIf brush holder is bent, replace it; if sliding surface is dirty,
clean.
Field Coil Check
1. Continuity test (between field coil positive terminal and positive
brushes).
INo continuity ... Replace field coil.
2. Insulation test (between field coil positive terminal and yoke).
IContinuity exists ... Replace field coil.

DISASSEMBLY
1. Check end play of front drive sprocket.
Standard:
0.2 - 0.35 mm (0.0079 - 0.0138 in)
If end play is beyond the maximum value, check front drive
sprocket and clutch gear for wear.
2. Remove retaining ring, speedometer drive gear and steel ball.
Be careful not to lose the steel ball.
3. Remove snap ring and spacer.
4. Press out front drive sprocket with mainshaft rear bearing and
clutch gear together.
