Purpose and function in a diesel engine

The presented piston with connecting rod is dedicated to 2.0 TDCi Diesel engines used in Ford Mondeo MK4 and Ford S-Max models. It is responsible for the precise transfer of combustion forces from the cylinder chamber to the crankshaft, which is crucial for the engine's smoothness, performance, and durability.

Selecting an element from the Pistons and rings group that complies with factory specifications helps reduce vibrations, maintain proper compression pressure, and ensure stable operation of the crankshaft system across the entire load range typical for diesel engines.

Technical characteristics and compatibility

As an OEM part from Ford, the piston with connecting rod is designed for the specific cylinder geometry, piston stroke, and loads characteristic of TDCi units. Using the correct component ensures:

• proper piston guidance in the cylinder liner,
• appropriate cooperation with piston rings,
• stable torque transfer to the crankshaft,
• maintenance of factory diesel engine operating parameters.

The presence of dedicated part numbers and interchangeable numbers (visible in the technical specification) facilitates verification of compatibility with a specific engine version and vehicle year, which is particularly important for diesel units where tolerances and design differences can be small but significant.

Component condition and service application

The offered piston with connecting rod is a used component, making it an attractive solution for diesel engine repairs where both technical correctness and cost optimization are important. This type of component is used, among others, for:

• partial engine overhaul (replacement of a single cylinder or section),
• repairs after seizure or mechanical damage to the piston,
• servicing engines after injection or turbocharging system failures that led to local damage in the combustion chamber.

Using an original element from the same design group allows for maintaining material and dimensional consistency with the remaining components of the crank-piston system.

Part selection by numbers and technical support

When selecting a piston with connecting rod for a Ford Mondeo MK4 or S-Max 2.0 TDCi, it is crucial to use the OEM part number and interchangeable numbers visible in the specification section. This helps avoid mistakes resulting from differences between engine versions, production changes, or modifications introduced during the model's lifecycle.

If you are planning a comprehensive repair or upgrade of the engine area in your Ford and need other elements from the same group, such as additional pistons, rings, or related crankshaft system components, check the available parts in the Ford Pistons and rings category.
