Purpose and Compatibility

The presented crankshaft for VW Polo V 6R is designed to work with the 1.2 TSI petrol engine designated CJZC. The construction adheres to the factory Volkswagen standard, which facilitates installation in place of a damaged component without the need for modifications to the block or lubrication system.

By maintaining the original crankshaft geometry, it is possible to ensure proper piston guidance, maintain the correct balance of the crankshaft-piston assembly, and stable engine operation across the entire RPM range.

Technical Characteristics of the Crankshaft

The crankshaft in this series has been developed for TSI petrol engines, where the combination of compact design and appropriate stiffness is crucial. Properly shaped main and connecting rod journals enable:

• maintaining predictable engine behavior under variable load,
• stable operation of the crankshaft assembly at higher rotational speeds,
• compatibility with the stock lubrication system and bearings in the 1.2 TSI CJZC engine.

The original crankshaft design ensures proper placement of oil channels and surfaces cooperating with the bearings, which is crucial for the durability of the entire petrol engine.

Benefits of Using an Original Crankshaft

Using an original Volkswagen crankshaft allows for the preservation of the engine's factory operating parameters. Compared to low-quality aftermarket parts, an OEM salvaged component offers:

• precise fit to the engine block and stock bearings,
• compliance with factory dimensional tolerances and balancing,
• consistency with service documentation and repair procedures used in workshops specializing in TSI engines.

For workshops and individual users, this means easier diagnostics, predictable installation, and reduced risk of problems arising from an improperly selected replacement part.

Application in TSI Engine Repairs

This crankshaft is suitable for comprehensive overhauls of the 1.2 TSI CJZC engine, such as:

• repair after seizure of the crankshaft-piston assembly,
• engine regeneration after bearing damage,
• engine rebuild after a failure requiring crankshaft replacement.

When combined with appropriately selected bearings, bolts, and accessories, the original crankshaft allows for restoring the efficiency of the TSI petrol engine in a manner close to factory standards.
