Womala Generator Drive Belt OE 30777807 for Volvo S40 V50 C30 Auto Engine Spare Parts

The Generator Drive Belt (OE Number: 30777807) is a critical power transmission component engineered for select Volvo models, responsible for transferring rotational force from the engine's crankshaft to the generator (alternator).

Constructed from high-strength ethylene propylene diene monomer (EPDM) rubber reinforced with a multi-layered polyester cord core, this belt combines flexibility with exceptional tensile strength (≥1500N). Unlike standard rubber belts, its EPDM composition resists heat aging, oil degradation, and ozone damage—ensuring reliable performance even in the high-temperature environment of the engine bay (operating range: -40°C to 120°C). Designed to Volvo's exact specifications, it features precise length and rib spacing to match the pulley systems of compatible models, guaranteeing smooth, slip-free operation.

• Power Transmission: Efficiently transfers crankshaft rotation to the generator, enabling it to convert mechanical energy into electrical energy—powering the vehicle's battery, lights, ignition system, and electronic components.
• Tension Stability: Maintains consistent tension across pulleys, preventing slippage that could reduce generator output (avoiding battery drain) or cause belt squealing.
• Durability: Withstands continuous flexing and contact with pulleys, boasting a service life of up to 60,000-100,000 km—significantly longer than conventional neoprene belts.
• System Compatibility: Works seamlessly with the engine's tensioner and idler pulleys, ensuring proper alignment and reducing wear on both the belt and pulley surfaces.

This generator drive belt is specifically designed for the following Volvo models:

As a direct OE replacement, it ensures precise fitment and optimal performance, making it essential for maintaining reliable electrical system operation in these models. Regular inspection (recommended every 30,000 km) and timely replacement prevent unexpected belt failure, which could lead to generator malfunction and vehicle breakdown.
