Overrunning Clutch Inspection

1. Check if the overrunning clutch moves along the

shaft freely. If not, replace the overrunning clutch

assembly.

2. Check if the overrunning clutch locks in one direc-

tion and rotates smoothly in reverse. If it does not

lock in either direction or it locks in both directions,

replace the overrunning clutch assembly.

3. Check if the starter drive gear is worn or damaged.

If the gear is worn or damaged, replace the over-

running clutch assembly; the gear is not available

separately.

NOTE: Check the condition of the flywheel or tor-

que converter ring gear if the starter drive gear

teeth are damaged.
Starter Reassembly

Reassemble the starter in the reverse order of

disassembly.

1. Pry back each brush spring with a screwdriver,

then position the brush about halfway out of its

holder, and release the spring to hold it there.

2. Install the armature in the housing. 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.

3. Install the end cover on the brush holder.
