TRUCK SERVICE MANUAL
3. When reinstalling the field frame lever housing
and nose housing align the etch marks scribed
when the motor was disassembled.
4. Starting motors with the end frame which utilize
eight brushes a. Pull the armature out of the
field frame just enough to permit the brushes to
be positioned over the commutator.
b. Push the commutator end frame and
armature back against the field frame.
5. On intermediate duty clutch motors, be sure to
assemble all brushes to the brush arms so the
long side of the brush is toward the commutator
end frame (the brush holes are offset).
Otherwise, the brushes may contact the riser
6. Be sure all wicks and oil reservoirs are saturated
with SAE10 oil and the splines were coated with
a light coat of SAE10 oil also. Lever housings
having a bearing and seal should have the
grease cavity between the bearing and seal filled
with Delco Remy Lubricant No. 1960954 or
equivalent (Fig. 3
There are no provisions for adjusting the pinion
clearance on motors using the intermediate duty clutch,
Fig. 2. However, the pinion clearance should be
checked on all motors after reassembly to insure proper
clearance. Check the pinion clearance as follow s:
1. Disconnect the motor field coil connector from
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,
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 will 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 the commutator
end to eliminate any over travel. Measure the
distance between the pinion stop and
