Inspection
EKS0031L
MAGNETIC SWITCH CHECK
●Before starting to check, disconnect battery ground cable.
●Disconnect “M” terminal of starter motor.
1. Continuity test (between “S” terminal and switch body).
●No continuity ... Replace.
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
condition 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.
●Excessive wear ... Replace.

Brush Spring Check
Check brush spring pressure with brush spring detached from brush.
●Not within the specified 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.
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:
Do not clamp yoke in a vice or strike it with a hammer.Spring pressure (with
new brush):Refer to SDS.SC-33,
"Starter" .

ARMATURE CHECK
1. Continuity test (between two segments side by side).
●No continuity ... Replace.
2. Insulation test (between each commutator bar and shaft).
●Continuity exists. ... Replace.
3. Check commutator surface.
●Rough ... Sand lightly with No. 500 - 600 emery paper.
4. Check diameter of commutator.
●Less than specified value ... Replace.

(0.020 to 0.031 in)
AssemblyEKS0031M
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 (QR engine models)
With pinion driven out by magnetic switch, push pinion back to
remove slack and measure clearance “l” between the front edge of
the pinion and the pinion stopper.
●Not in the specified value ... Adjust by adjusting plate.

Movement ( YD engine models)
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.
●Not in the specified value...Adjust by adjusting plate.Movement “ ”Refer to SDS.SC-33,
