(c) To force retainer over snap ring, place a
suitable washer over shaft and squeeze retainer and
washer together with pliers (fig. 1F-8).

(d) Remove washer.
(e) Slide thrust collar over shaft.
(2) Refer to disassembly procedure and follow in
reverse order to complete reassembly.
(3) When solenoid is installed, apply sealing com
pound between motor frame, flange, and solenoid
junction.
Pinion Gear Clearance Test
The pinion gear clearance cannot be adjusted but
should be tested after reassembly of the starter motor to
ensure proper clearance. Improper clearance is an in
dication of worn parts.
To measure pinion gear clearance, follow the steps
listed below:
(1) Disconnect starter motor field winding con
nector from solenoid motor M-terminal and THOR
OUGHLY INSULATE IT.
(2) Connect battery between solenoid switch S-ter-
minal and starter motor frame (fig. 1F-9).

(3) MOMENTARILY flash jumper lead from sole
noid motor terminal (M) to starter motor frame. This
will shift pinion gear into cranking position and it will
remain in this position until battery is disconnected.
(4 ) Push pinion gear back toward commutator end
to eliminate any slack.
(5) Measure distance between pinion gear and pin
ion gear stop with feeler gauge (fig. 1F-10). Acceptable
distance is 0.010 to 0.140 inch (0.0254 to 3.556 mm).
