FAQ

What exactly is the purpose/function of this component?
This internal engine component absorbs forces generated by combustion or the valve train and transmits them to the corresponding mechanical components within the engine. Dimensional accuracy, material condition, and surface quality are essential for its function and service life.

How can you recognize a defect or typical symptoms?
Typical symptoms include mechanical noises, loss of power, compression deviation, increased oil consumption, or metal particles in the oil. Wear, scoring, thermal overload, or dimensional deviations directly affect engine performance.

How is the component inspected or tested?
Dimensions, clearance, surfaces, straightness or concentricity, and the wear pattern on the contact surfaces are inspected according to workshop specifications. Additionally, compression, leak-down, or valve clearance measurements provide insight into the component’s condition when installed in the engine.

When should it be replaced?
The part should be replaced if wear limits are exceeded, or if cracks, seizure marks, or thermal damage are present. As part of an engine overhaul, heavily loaded internal components are often replaced as a precautionary measure.

How do you check compatibility?
Important factors include the OEM part number, engine type, dimensional group, standard or oversize, installation orientation, and corresponding mating parts. Changes to the serial number and the engine’s machining status must also be taken into account.
