Purpose and technical characteristics

The presented crankshaft is structurally matched to Diesel engines used in Volkswagen, Audi, and Seat models from the TDI family. The geometry of the main and connecting rod journals, oil channels, and counterweight layout are designed for the specific loads of 1.9 and 2.0 TDI units, ensuring stable operation of the crank-piston system across the full RPM range.

Original manufacturing guarantees adherence to factory dimensional tolerances, ensuring the crankshaft works correctly with the engine block, bearings, and flywheel. This solution is particularly beneficial for overhauls where maintaining compliance with the manufacturer's service documentation is crucial.

Benefits of using an original crankshaft

Using an original crankshaft in a TDI engine helps maintain proper engine refinement, reduce torsional vibrations, and ensure even load distribution on the bearings. In practice, this translates into:

• stable oil pressure in the crankshaft and connecting rod lubrication system,
• proper cooperation with the stock dual-mass or solid flywheel,
• preservation of factory torque parameters and engine durability.

For workshops and private users, this means a lower risk of repeat repairs and the ability to precisely match other crank assembly components, such as bearings or connecting rods.

Product condition and use in service practice

The crankshaft is a used part, which in the case of original parts from disassembly represents a reasonable compromise between repair costs and maintaining factory specifications. This type of component is often chosen for TDI engine overhauls where compliance with the manufacturer's solutions and the possibility of further workshop processing (e.g., measurements, potential grinding if necessary) are important.

Thanks to its original design, the crankshaft can be used both for standard engine rebuilds and for more advanced repairs where precise control of clearances and alignment in the crank system is required.

Part selection and compatibility

The item has a dedicated OEM part number and associated interchangeable numbers, which facilitates clear identification in service catalogs and parts selection systems. When planning an engine overhaul, it is worth verifying compatibility with the specific version of the TDI unit and the vehicle's model year to ensure full compatibility with the block, connecting rods, and accessories.
