commutator down. Position snap ring on upper end of
shaft and hold in place with a block of wood. Hit wood
block a blow with hammer, forcing snap ring over end
of shaft. Slide snap ring past the grease groove to the
snap ring groove (Fig. 6E-7).
e. Assemble thrust collar on shaft with shoulder next to
snap ring (Fig. 6E-8).
f. Place armature flat on work bench, and position
retainer and thrust collar next to snap ring. Then,
using two pairs of pliers at same time (one pair on
either side of shaft), grip retainer and thrust collar and
squeeze until retainer is forced over. snap ring (Fig.

2. Place a small amount of high melting point grease
in drive housing bushing. Make sure thrust collar is in
place against snap ring and retainer and slide
armature and clutch into place in drive housing,
engaging shift lever with clutch.
3. Position field frame over armature, apply sealing
compound between frame and solenoid case. Position
frame carefully against drive housing to prevent
damage to brushes.
4. Place a small amount of high melting point grease
in bushing in commutatoP end frame. Place leather
thrust washer on armature shaft and slide commutator
end frame onto shaft.
5. Install through bolts and tighten securely.
6. R e c o ~ e c t field coil leads to solenoid terminal.
PINION CLEARANCE CHECK
There is no provision for adjusting pinion clearance on
the enclosed shift lever cranking motor. When the shift
lever mechanism is correctly assembled, the pinion
clearance should fall within the specified limits
(.010"-.040"). When clearance exceeds these limits, it
may indicate excessive wear of solenoid linkage or
shift lever yoke buttons.
Pinion clearance should be checked after motor has
been disassembled and reassembled.
Check pinion clearance in fallowing manner:
1. Disco~ect the motor field mil connector from the
solenoid motor
terminal
and insulate it carefully.
2.
C o ~ c c t
one battery lead to the solenoid switch
terminal and the other to the solenoid frame (Fig. 6E
9).
3. Flash a jumper lead momentarily from the solenoid
motor terminal to the solenoid frame. This will shift
the pinion into cranking position and it will remain so
until the battery is
discm~ected.
