(f)

Temporarily tighten the terminal nuts.

(g)

Tighten the terminal nut
(1)

Put a wooden block on the contact plate and press
it down with a hand press.

Dimensions of wooden block:
20 x 37 x 40 mm (0.79 x 1.46 x 1.57 in.)
Press force:
981 N (100 kgf, 221 lbf)

NOTICE:

Check the diameter of the hand press ram. Then 
calculate the gauge pressure of the press when 
981 N (100 kgf, 221 lbf) of force is applied.
Gauge pressure:

If the contact plate is not pressed down with the spe-
cified pressure, the contact plate may tilt due to coil
deformation or the tightening of the nut.

(2)

Using SST, tighten the nuts to the specified torque.

SST

09810–38140

Torque: 17 N·m (173 kgf·cm, 13 ft·lbf)

NOTICE:
If the nut is over tightened, it may cause cracks on the in-
side of the insulator.

TEST

NOTICE:
These tests must be done within 3 to 5 seconds to avoid
burning out the coil.
1.

DO PULL–IN TEST

(a)

Disconnect the field coil lead wire from terminal C.

(b)

Connect the battery to the magnetic switch as shown.
Check that the pinion gear moves outward.

2.

DO HOLD–IN TEST

While connected as above with the pinion gear out, disconnect
the negative (–) lead from terminal C.
Check that the pinion gear remains out.

3.

INSPECT CLUTCH PINION GEAR RETURN

Disconnect the negative (–) lead from the starter body.
Check that the pinion gear returns inward.

4.

DO NO–LOAD PERFORMANCE TEST

(a)

Connect the battery and ammeter to the starter as shown.

(b)

Check that the starter rotates smoothly and steadily with
the pinion gear moving out. Check that the ammeter
shows the specified current.
Specified current: 90 A or less at 11.5 V
