059105251DA Engine Crank Crankshaft pulley for Audi A6 C7 4G

Engine Crankshaft Pulley for Audi A6 C7 4G (059105251DA)

1. Part Number: This engine crankshaft pulley is designed with the OEM part number 059105251DA, ensuring precise compatibility with Audi A6 C7 4G models. The code validates its authenticity and guarantees a factory-spec fit for optimal engine performance.
2. Vehicle Compatibility: Specifically engineered for:
   • Audi A6 C7 (4G): 2011–2018
     Suits 2.0L TDI (CRHC, CAGA), 3.0L TDI (CASA, CCWA), and 3.0L supercharged V6 (CREC) engines. Verify your vehicle’s engine code (e.g., CRHC for 2.0L TDI) and production year for exact fitment.
3. Function and Quality: The crankshaft pulley transfers rotational force from the crankshaft to accessory belts (e.g., alternator, air conditioning, water pump), while its integrated vibration damper reduces harmonic vibrations to protect engine components. Constructed from high-strength cast iron with a precision-machined outer rim and rubber-isolated damper core, it withstands rotational speeds up to 7,000 RPM and temperatures up to 120°C. The pulley features keyed slots for precise timing alignment and a corrosion-resistant finish. Replace worn pulleys showing signs of cracking, belt slippage, or damper degradation to prevent belt failure and accessory system damage.
