Starter motor
General description
The Prestolite S115 starter motor has a smooth cylinder surface with no protrusions. This is because the
solenoid and the main switch assemblies are inside the drive end cover around (co-axially with) the armature
shaft. The main feature of the co-axial starter is that only the pinion assembly moves axially to engage the
engine flywheel. There is no axial movement of the whole armature as with the axial type motor. To ensure
smooth engagement of the pinion, full load is not applied until the pinion is completely engaged with the
flywheel.
The Prestolite PE129 is a pre-engaged starter motor and is actuated by a solenoid. The solenoid is fitted to
the starter motor outer casing. When the starter button or key is operated, the solenoid pulls a lever to engage
the pinion in the starter ring, against spring pressure. As soon as the pinion is fully in mesh with the starter ring,
the starter relay electrically connects the starter motor directly to the batteries. When the engine runs, the
starter button or key is released, current to the solenoid is stopped and the solenoid is de-energised. Current
to the starter motor from the batteries is stopped. Spring pressure on the lever disengages the pinion from the
starter ring.
