Electric Starters

These engines use inertia drive starting motors.
Operation
When power is applied to the starter, the armature
rotates. As the armature rotates, the drive pinion
cranks the engine.
than the starter armature and drive pinion. This
moves the drive pinion out of mesh with the ring
gear and into the retracted position. When power is
removed from the starter, the armature stops rotating
and the drive pinion is held in the retracted position

Starting Motor Precautions

NOTE: Do not crank the engine continuously for
more than 10 seconds at a time. If the engine
does not start, allow a 60-second cool-down
to follow these guidelines can burn out the
starter motor.

1. Clean corroded connections and tighten loose connections.
Wiring
2. Replace wires in poor condition.
1. Bypass the switch or solenoid with a jumper wire. If starter cranks
normally, replace the faulty components.
Battery
1. Check for excessively dirty or worn brushes and commutator.
Brushes
Clean commutator using a coarse cloth (not emery cloth).
2. Replace brushes if excessively or unevenly worn.
1. Make sure the clutch or transmission is disengaged or placed in
neutral. This is especially important on equipment with
hydrostatic drive. The transmission must be exactly in neutral to
or
prevent resistance which could keep the engine from starting.

2. Check for seized engine components such as the bearings,
connecting rod, and piston.

NOTE: If the starter does not crank the engine, shut
condition is corrected.
NOTE: Do not drop the starter or strike the starter
frame or end cap. Doing so can damage the
starter.
