Purpose and technical characteristics

The presented crankshaft is designed for 2.0 TDCi units powered by diesel fuel, used in Ford Mondeo MK4 and Ford S-Max models. The crankshaft construction is adapted to the loads characteristic of diesel engines – high torque, high combustion pressures, and long-term operation in varied road conditions.

This component is responsible for converting the reciprocating motion of the pistons into rotational motion; therefore, its geometry, balance, and the surface quality of the journals are crucial for the engine's smooth operation, vibration levels, and the durability of the main and connecting rod bearings.

Benefits of using an original Ford crankshaft

Using an original crankshaft in a 2.0 TDCi engine allows for maintaining the factory performance parameters of the power unit. Proper fitment to the engine block, connecting rods, and lubrication system translates into:

• stable engine operation across the entire RPM range,
• reduction of vibrations and noise resulting from improper balancing,
• correct interaction with bearings and the lubrication system,
• increased resistance to loads typical for diesel engines.

For Ford users, this means more predictable vehicle behavior, better engine refinement, and the possibility of continued operation without the need for costly modifications.

Condition, verification, and practical application

The offered crankshaft is a used part, which in workshop practice often represents a reasonable compromise between repair costs and maintaining appropriate technical parameters. This type of component is a popular choice for engine overhauls where matching the specific unit and adhering to the manufacturer's factory specifications is key.

Before installation, standard workshop procedures are recommended, such as checking geometry, measuring journals, verifying the potential need for grinding, and selecting appropriate bearings. Thanks to this, the crankshaft can be safely used both for routine repairs and for a comprehensive rebuild of the 2.0 TDCi engine in a Ford Mondeo MK4 or S-Max.

Technical support and project development

For those planning broader engine modifications or building a project with increased power, a used crankshaft can serve as a good base for further work – from a standard overhaul to more advanced configurations. In such cases, it is worth checking out tips on component selection and budget optimization, which you can find in the article The best used parts for tuning your car.
