DESCRIPTION AND OPERATION
STARTING SYSTEM
The new Delco Remy starter for 1973 is a brush-
type series wound electric motor equipped with an
overrunning clutch and operated by a
The
frame is enclosed by the commutator end frame
and the drive housing and carries the pole shoes and
the
coils. The armature has a on the drive
end which carries the over-running clutch and pinion
assembly. The armature shaft is supported in
bronze bushings in the end
and the drive end housing. These bushings are

require no additional lubrication between overhaul
periods.
As the starter is operated by turning the ignition
switch on the instrument panel, the shift lever is
moved against spring tension. By means of the guide
ring, the shift lever moves the pinion into mesh with
the flywheel ring gear.
After the
pinion meshes with the flywheel ring gear
teeth, the solenoid contact disc closes the circuit and
the engine is cranked. When the engine starts, the
speed of the rotating flywheel causes the pinion to
over-run the clutch and armature. The pinion con-
tinues to be engaged as long as the shift lever is kept
in the cranking position.
In case of cranking motor breakdown, it should be kept in mind that the
relevant cause(s) for the trouble may not only lie in the cranking motor itself
