16. Check the planetary gears (A) and ring gear {B).Replace them if they are worn or damaged.
Overrunning Cluich Inspection
17. Slide the overrunning clutch along the shaft.
Replace it if it does not slide smoothly.
18. Rotate the overrunning clutch (A) both ways.
Does it lock in one direction and rotate smoothly inreverse? lf it does not lock in either direction or it
locks in both directions, replace it.
lf the starter drive gear (B) is worn or damaged,
replace the overrunning clutch assembly; the gear
is not available separately.
Check the condition of the flywheel ring gear.
Replace it if the starter drive gear teeth are
oamageo.

Starter Reassembly
20, Pry back each brush spring with a screwdriver, thenposition the brush about halfway out of its holder,
and release the spring to hold it there.
NOTE: To seatthe new brushes. slip a strip of #5OO
or # 600 sandpaper. with the grit side out, be&veen
the commutator and each brush, and smoothly
rotate the armature. The contact surface of the
brushes will be sanded to the same contour as the
commutator.
21lnstallthe armature in the housing, and installthe
brush holder. Next, pry back each brush spring
again, and push the brush down until it seats
against the commutator, then release the spring
against the end of the brush.

Install the starter end cover to retain the brush
holder.

SRS components are located in this area. Reviewthe SRS component locations (see page 23-'13) and precautions andprocedures (see page 23-14) in the SRS section before performing repairs or service.
1. Disconnect the 14P connector from the control unit.
2. Inspect the connector and socket terminals to be sure they are all making good contact.
. lf the terminals are bent, loose, orcorroded, repairthem as necessary, and recheckthe system.. lf the terminals look OK, go to step 3.

control actuator (B).
Remove the cover (A), and check the output linkage
(B) for smooth movement.
2.

Connect battery power to the No, 2 terminal and
ground to the No. 1 terminal.
Check for a clicking sound from the magnetic clutch.
The output linkage should be locked.
lf the output linkage is not locked, replace the
