PROCEDURE

1. INSPECT STARTER ASSEMBLY

CAUTION:

As a large electric current passes through the cable during this inspection, a thick cable must be used. If not, the cable may become hot and cause injury.

NOTICE:

The following tests must each be performed within 3 to 5 seconds to prevent the coil from burning out.

(a) Mount the starter in a vise between aluminum plates.

NOTICE:

Do not overtighten the vise.

(b) Perform the pull-in test.

(1) Remove the nut and disconnect the lead wire from terminal C.

(2) Connect the battery to the magnet starter switch as shown in the illustration. Then check that the clutch pinion gear extends.

Terminal C

If the clutch pinion gear does not move, replace the magnet starter switch assembly.

(c) Perform a holding test.

(1) Disconnect the negative (-) terminal lead from terminal C with the condition specified in the pull-in test above being maintained. Check that the pinion gear remains out.

Terminal C

If the clutch pinion gear returns inward, replace the magnet starter switch assembly.

(d) Inspect the clutch pinion gear return.

(1) Disconnect the negative (-) terminal lead from the starter body. Check that the clutch pinion gear returns inward. If the clutch pinion gear does not return inward, replace the magnet starter switch assembly.

If the clutch pinion gear does not return inward, replace the magnet starter switch assembly

(e) Perform an operation test without load.

(1) Connect the lead wire to the terminal C with the nut.

Torque:

5.9 N·m {60 kgf·cm, 52 in·lbf}

(2) Connect the battery and an ammeter to the starter as shown in the illustration.

(3) Check that the starter rotates smoothly and steadily while the pinion gear is extended. Then measure the current

Standard current:

90 A or less at 11.5 V

If the result is not as specified, inspect the starter assembly.

HINT:

Inspect the starter brush holder assembly, starter yoke assembly and starter armature assembly. If there is a malfunction, replace the part and perform this test again.
