27.1 Inspection before disassembly
(inspection of assembly)
If an abnormality is found, disassemble and repair.
1. Pinion gap
1) Connect the positive (+) cable of the battery to
terminal S of the starter and the negative (-)
cable to the starter body to extend the pinion.
2) Lightly press the tip of the extended pinion
shaft with a finger, and measure the distance
of the shaft movement.
3) If the measured value is not within a range of
0.1 to 2.5 mm [0.0039 to 0.0984 in.], increase
or decrease the number of packings at the
magnetic switch section for adjustment. An
increase of packings results in a decrease of
the pinion gap.
2. No-load test
1) As shown in the diagram, connect an
ammeter, voltmeter, revolution indicator and
battery.
2) Turning on the switch should extend the pinion
and operate the starter at the specified speed
or faster.
If the current or rotating speed does not
conform to the standard value, disassemble
the starter for inspection and repair.
