ASSEMBLING
Type I Starter Drive
Begin by assembling the following parts
in the order given. The accompanying illus-
tration will be most helpful in assembling
the parts in the proper sequence. First,
slide the thrust washer onto the armature
shaft. Next, and in the sequence given,
install the cushion spacer; cushion; cushion
cup with the open end over the cushion; the
cup; and then the thrust washer.
Install the screw shaft with the splined
end facing UP. Lubricate the underside with
Multipurpose Lubricant, or equivalent. In-
stall the pinion gear with the screw end
facing DOWN.
Install the anti-drift spring washer, anti-
dr ift spring, and the pinion gear stop with
the recessed end facing DOWN.
Secure the assembly with the cast illated
nut tightened to a torque value of 200 in.-
lbs, Now, turn the nut slightly more until
the cotter pin can be inserted through the
nut and the hole in the shaft. Some models
use a self-locking nut without, the cotter
key.
To test the complete sta.rter motor, pro-
ceed directly to Section 6-16.
To install the starter motor onto the
engine, if no further work is to be perform-
ed, proceed directly to Section 6-17.
DISASSEMBLING
Type II Drive Gear with Rubber Cushion
First, remove the nut from the end of
the armature shaft. Scribe a mark on the
top of the screw shaft and one of the top of
the pinion as an aid during assembling.
These marks will identify the top of both
parts. Next, remove the following parts in
the sequence given: The pinion stop; anti-
drift spring; sleeve; screw shaft cup; screw
shaft; pinion; thrust washer; cushion cap;
cushion; and the cushion retainer. The ex-
ploded drawing accompanying this section
will be helpful in assembling the starter
motor in the proper sequence.
CLEANING AND INSPECTING
Inspect the drive gear teeth for chips,
cracks, or a broken tooth. Check the spline
inside the drive gear for burrs and to be sure
the drive gear moves freely
on the armature
shaft. Check to be sure the return spring is
flexible and has not become distorted. In-
spect the rubber cushion for cracks and for
signs of oil on the cushion. Clean the
armature shaft with crocus cloth.
