Auto Spare Parts Generator Pulley OE 31285489 for Volvo XC60 V60 S80 S60 S80L V70
This OE-grade generator pulley is tailored for multiple Volvo models, including XC60 (-17), V60 (-18), S80 (07-), S60 (11-18), S80L, and V70 (08-). Mounted on the generator (alternator) shaft, it follows Volvo’s original standards for size, groove design, and material strength—ensuring seamless compatibility with the vehicle’s accessory belt system and stable power transmission.
Core Components & Functions
Core Component
The pulley is made of high-strength steel or aluminum alloy (per OE specs), with precision-machined grooves to match the accessory belt’s width and pitch. It features a durable anti-rust coating (e.g., zinc plating) to resist under-hood moisture and corrosion.
Core Functions
Power Transmission: Transfers rotational force from the engine’s crankshaft (via the accessory belt) to the generator, enabling the generator to convert mechanical energy into electrical energy—charging the battery and powering the vehicle’s electrical systems (lights, infotainment, etc.).
Belt Alignment: The pulley’s precise groove design keeps the accessory belt centered, preventing belt slippage (which causes generator inefficiency) or premature belt wear.
Stable Operation: High-strength materials withstand constant rotational stress and under-hood temperature fluctuations (-30℃ to 120℃), ensuring long-term reliable performance.

Installation & Usage Notes
Confirm the pulley matches the vehicle’s engine type via VIN—different engine variants may have pulleys with varying groove counts or shaft fits. Installation requires professional tools (e.g., pulley puller, torque wrench) and adherence to the Volvo service manual: disconnect the battery first, remove the accessory belt, use a pulley puller to detach the old pulley, and secure the new one to the generator shaft with OE-specified torque (typically 25–35 N·m). After installation, reattach the belt, check for proper alignment, and test the generator’s charging output (normal range: 13.5–14.5V). Inspect the pulley annually for cracks or groove wear—replace if damaged to avoid belt failure or generator damage.
