3.
The
remaining
portion
of
the
starting
motor
reassembly
procedure
is
the
reverse
of
the
disassembly.
4.
When
installing
the
solenoid,
apply
sealing
compound between field frame and solenoid flange.
PINION CLEARANCE
Pinion
clearance
should
be
inspected
after
reassembly of the motor to insure proper adjustment. Check
pinion clearance following the steps listed below.
1.
Disconnect the motor field coil connector from the
solenoid motor terminal.
CAREFULLY INSULATE IT.
2.
Connect a battery, of the same voltage as the
solenoid, one lead to solenoid switch terminal and
the other to the starter or solenoid frame, Fig. 12.
Fig. 12 Pinion Drive Clearance Check Hookup
3.
Connect a jumper wire to the starting motor terminal
on the solenoid; then touch the second end to the
motor frame. This will shift the pinion into cranking
position and remain until the battery is disconnected.
CAUTION: Do not keep the jumper wire connected
too long as overheating of the solenoid may result.
4.
Push the pinion back towards commutator end to
eliminate any overtravel. Then measure the distance
between the pinion stop and pinion. The clearance
should be .01 to .14, Fig. 13.
Fig. 13 Checking Pinion Clearance
There are no provisions for adjusting the pinion
clearance on the enclosed shift lever type starting motors.
Therefore, if the pinion clearance does not fall within the
specified limits (.01 to .14), inspect the solenoid linkage or
shift lever yoke buttons for excessive wear.
