Starter motor

STARTER MOTOR

The starter motor cranks the engine overcoming the inertia and friction, and bringing it to a determine rpm that can start the formation of the mixture required for combustion and thus autonomous movement of the engine itself.

The movement is transmitted by an direct current electric motora operated by the battery, through an engagement pinion which turns the special rings gear machined on the flywheel.

1. Pinion
2. Roller idler wheel
3. Engagement lever
4. Energising winding
5. Relay
6. Stator
7. Flywheel ring gear

Owing to an idler wheel engagement, the pinion disengages when the main engine turns faster than the motor.

A relay energised by the motor current engages the pinion through a fork.

The starter motor is of the translation and screwing type, with relay housed directly above the motor.

REMOVING/REFITTING
