Womala Engine Crankshaft Pulley A2750300003 Crankshaft Pulley for Mercedes Benz W463 W220

Core Functions

• Power Transmission: Converts the crankshaft’s rotational motion into usable power for accessories. This enables the alternator to charge the battery, the power steering pump to provide steering assistance, and the AC compressor to cool the cabin—ensuring all auxiliary systems operate in sync with the engine.
• Vibration Damping: The built-in rubber damping layer absorbs torsional vibrations from the crankshaft. This reduces stress on the drive belt and accessory bearings, minimizing noise (e.g., belt squeal) and extending the service life of connected components.
• Belt Alignment: Features a precision-machined groove for the drive belt, maintaining accurate alignment. Proper alignment prevents uneven belt wear, slippage (which reduces accessory efficiency), and premature belt replacement.

 Compatible Vehicles

This Engine Crankshaft Pulley (OE: A2750300003) is tailored for Mercedes Benz W463/W220 models and their corresponding engine codes:

1. This pulley is model and engine-specific—it only fits Mercedes Benz W463 (e.g., G-Class) and W220 (e.g., S-Class) models equipped with M275, M277, or M279 V12 engines. Do not use it for other Mercedes Benz model series.
2. When replacing, confirm the exact engine code (e.g., M275 E55 vs. M279 E60) via the vehicle’s VIN or engine bay label—minor differences in engine displacement may affect fitment.
3. Post-installation, check drive belt tension and alignment using Mercedes Benz’s official diagnostic tools to avoid accessory malfunction or belt damage.
