OEM reference number: 71719607, cross-reference numbers: M000T82081, M000T85381, 5802CW, 9625168580, Valeo 438092, Bosch 0986021600. Direct aftermarket replacement for multiple European vehicle models.

1. Light-weight cast-aluminum housing delivers excellent heat dissipation and anti-corrosion performance, adapting to complex under-hood operating conditions.
2. Integrated electromagnetic solenoid assembled with Bendix overrunning clutch mechanism.
3. 9-tooth drive pinion with clockwise rotation viewed from pinion side.
4. High-quality copper-wound armature, heavy-duty carbon brushes and reinforced commutator ensure stable cranking performance for gasoline engines.
5. Three-hole flange mounting with M8 bolt holes for quick and precise installation.
6. Every finished starter passes strict factory tests including no-load test, load torque test and insulation withstand-voltage test.
7. Compact overall dimension with reliable cold-start capability. Custom branding and private-label services are available for bulk orders.

This starter converts 12V DC electrical energy supplied by the vehicle battery into mechanical cranking torque through four sequential working phases:

1. Solenoid Excitation: When the ignition switch is turned to START position, low-current control signal energizes the internal solenoid coil. Magnetic force pulls the metal plunger forward.
2. Pinion Axial Engagement: The plunger drives the shift fork to slide the 9-tooth pinion outward axially until fully meshed with the engine flywheel ring gear.
3. Engine Cranking Output: After complete gear engagement, the solenoid closes heavy-duty internal contact points. High electric current flows into the DC armature motor. Rotation torque is amplified by the planetary gear set to drive the flywheel and crank the petrol engine for ignition.
4. Automatic Anti-Reverse Protection: Once the engine ignites and rotates faster than the pinion speed, the built-in overrunning clutch slips to prevent reverse rotation damage to the starter assembly. The solenoid is de-energized, and a return spring pulls the pinion back to idle position automatically.

This starter is widely used for Fiat-group and PSA European petrol vehicles. It meets aftermarket replacement standards and solves common starter faults: no cranking, weak cranking and abnormal operating noise.
