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.

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).
