Purpose and compatibility

The presented crankshaft has been designed specifically for the 1.2 TSI CGPB unit installed in the Volkswagen Polo V 6R petrol model. The appropriate selection of journal geometry, oil channels, and surfaces interacting with the bearings ensures that this component is perfectly matched to the operating characteristics of this turbocharged engine.

By maintaining factory design parameters, the crankshaft works seamlessly with the original lubrication system, pistons, and connecting rods, which facilitates installation and reduces the risk of balancing issues or improper bearing clearance.

Construction and role in the crank-piston system

The crankshaft in the 1.2 TSI CGPB engine is responsible for converting the reciprocating motion of the pistons into rotational motion transmitted to the gearbox. Key design features of this component include:

• precision-machined main and connecting rod journals that work with the bearings,
• oil channels ensuring stable lubrication across the entire RPM range,
• shape and mass optimized for balance and reduction of torsional vibrations,
• resistance to loads resulting from the operation of a turbocharged petrol engine.

A crankshaft constructed in this way allows for maintaining smooth engine operation, reducing vibrations, and ensuring the proper durability of the entire crank-piston system.

Characteristics of the used part

The offered crankshaft is a used part, sourced from dismantling. For many users, this is a cost-effective solution while maintaining the original quality of Volkswagen parts. In practice, this means the ability to restore the efficiency of the 1.2 TSI CGPB engine without the need to invest in a new component, while maintaining compliance with factory specifications.

Before installation, standard workshop procedures are recommended: thorough cleaning, inspection of journal surfaces, measurement of bearing clearances, and verification of balance in accordance with the service documentation for the specific engine.

Benefits of using an original crankshaft

Using an original crankshaft in the 1.2 TSI CGPB engine provides a number of practical benefits:

• Factory fit – maintaining original geometry and dimensions facilitates installation and minimizes the risk of operational problems.
• Consistency with the lubrication system – oil channels and mating surfaces are designed for the specific TSI petrol engine.
• Stable engine operation – proper crankshaft balancing affects engine refinement, vibration levels, and noise.
• Economical repair – a used OEM part allows for reducing repair costs compared to a new component.

Selection and verification of parts by numbers

When selecting a crankshaft for a Volkswagen Polo V 6R with a 1.2 TSI CGPB engine, it is crucial to compare vehicle data (engine code, production year, displacement, fuel type) with the information in the specification. It is also worth verifying compatibility using the OEM number and interchangeable numbers to ensure that the component will work correctly with the engine block and accessories.
