2) Disconnect connector from terminal M, and
connect positive terminal of battery and terminal M
using a lead wire and ground terminal to starter
body.
In this test set up, pinion should return to its origi-
nal position even when it is pulled out with a screw-
driver.
S6M0393A
(A) Terminal S
(B) Terminal M
2. PINION GAP
1) With pinion forced endwise on shaft, as outlined
in step 1) before measure
pinion gap.
Pinion gap:
0.5 Ð 2.0 mm (0.020 Ð 0.079 in)
S6M0394A
(A) Pinion
(B) Gap
(C) Stopper
If motor is running with the pinion forced endwise
on the shaft, disconnect connector from terminal M
of switch assembly and connect terminal M to
ground terminal (þ) of battery with a lead wire.
Next, gently push pinion back with your fingertips
and measure pinion gap.
2) If pinion gap is outside specified range, remove
or add number of adjustment washers used on the
mounting surface of switch assembly until correct
pinion gap is obtained.
3. PERFORMANCE TEST
The starter should be submitted to performance
tests whenever it has been overhauled, to assure
its satisfactory performance when installed on the
engine.
Three performance tests, no-load test, load test,
and lock test, are presented here; however, if the
load test and lock test cannot be performed, carry
out at least the no-load test.
For these performance tests, use the circuit shown
in figure.
S6M0395A
(A) Variable resistance
(B) Magnetic switch
(C) Starter body
1) No-load test
With switch on, adjust the variable resistance to
obtain 11 V, take the ammeter reading and mea-
sure the starter speed. Compare these values with
the specifications.
No-load test (Standard):
Voltage / Current
11V/90Amax.
Rotating speed
MT vehicles
2,800 rpm or more
AT vehicles
2,400 rpm or more
2) Load test
Apply the specified braking torque to starter. The
condition is satisfactory if the current draw and
starter speed are within specifications.
Load test (Standard):
Voltage / Load
MT vehicles
7.5 V/8.7 N´m (0.89 kg-m, 6.4 ft-lb)
AT vehicles

position by passing a [2 mm (0.08 in) dia. length 4
to 5 cm (1.6 to 2.0 in)] wire (A) through the hole
shown in the figure.
CAUTION:
Be sure to remove the wire after reassembly.

2) Heat the bearing box in the rear bracket [50 to
60ÉC (122 to 140ÉF)] and press the rear bearing
into the rear bracket.
CAUTION:
Grease should not be applied for the rear bear-
ing. Remove oil completely if it is found on the
bearing box.
3) After reassembly, turn the pulley by hand to
check that the rotor turns smoothly.

Tightening torque (Spark plug):
20.6
±2.9 N´m (2.10±0.30 kg-m, 15.19±2.14
ft-lb)
CAUTION:
The above torque should be only applied to
new spark plugs without oil on their threads.
In case their threads are lubricated, the torque
should be reduced by approximately 1/3 of the
specified torque in order to avoid over-stress-
ing.
B: INSPECTION
Check electrodes and inner and outer porcelain of
plugs, noting the type of deposits and the degree
of electrode erosion.
S6M0420A
(A) Electrode gap
(B) Carbon accumulation or wear
(C) Cracks
(D) Damage
(E) Damaged gasket
1) Normal
Brown to grayish-tan deposits and slight electrode
wear indicate correct spark plug heat range.
G6M0087
2) Carbon fouled
Dry fluffy carbon deposits on insulator and elec-
trode are mostly caused by slow speed driving in
city, weak ignition, too rich fuel mixture, dirty air
cleaner, etc.
It is advisable to replace with plugs having hotter
heat range.
G6M0088
3) Oil fouled
Wet black deposits show excessive oil entrance
into combustion chamber through worn rings and
pistons or excessive clearance between valve
guides and stems. If same condition remains after
repair, use a hotter plug.
G6M0089
4) Overheating
White or light gray insulator with black or gray
brown spots and bluish burnt electrodes indicate
engine overheating. Moreover, the appearance
results from incorrect ignition timing, loose spark
plugs, wrong selection of fuel, hotter range plug,
etc. It is advisable to replace with plugs having
colder heat range.
