Install dowels (6). Set the field frame (5)
solenoid to the solenoid switch terminal and to the
solenoid frame or ground terminal. Momentarily flash a
over the armature onto the lever housing. Install washer
jumper from the solenoid motor terminal to the solenoid
(15) and end frame (4) and secure the end frame with
frame or ground terminal. This will shift the drive into

cranking position. Using a feeler gage measure the
clearance between the drive pinion and stop collar (12).
insert the plunger (47) in the solenoid, aline the mounting
Move drive assembly by hand to give a clearance of .010
holes of the solenoid and field frame and secure with
to .140 between the pinion and collar. Remove jumpers
and replace connection between field coil and solenoid.
Saturate the three oiling wicks with NO. 10
n. Refer to TM 5-3810-294-20 and install the
starting motor on the engine.
m. Check drive pinion clearance as follow:
Disconnect field coil connection from solenoid motor.
Connect a battery of the same voltage as the

surges of spark plug power for most efficient engine
The distributor opens and closes the circuit between the
low voltage source and the ignition coil that the primary
coil winding of the coil obtains intermittent surges of
current. These surges build up magnetic fields around
