Removal/refitting

The starter motor, overcoming inertia and friction, cranks the engine to a set number of revolutions in order to begin the formation of the air-fuel mixture necessary for combustion and subsequent autonomous movement of the engine.

The movement is transmitted by a direct current electric motor powered by battery voltage through a drive pinion which rotates the ring gear on the engine flywheel.

Due to a free-wheel coupling the pinion disengages when the main engine unit rotates at a greater speed than the motor.

A relay, excited by the current from the motor, engages the pinion by way of a fork.

The starter motor installed on the vehicle is of the translating, screw pinion type with the relay located directly above the starter motor.

The starter is fixed to the engine by a bracket and a metallic shield protects it from excessive heat

REMOVAL/REFITTING

1. Place the vehicle on a lift.
   • Disconnect the negative cable from the battery.
