🔧 Product Description

This is a genuine Volvo Penta 2-groove pulley from the cooling system group, part number 11032857. It transmits drive from the engine's belt system to the coolant circulation pump, and its two-groove profile is what distinguishes it from single- and multi-groove alternatives sharing the same name. It suits TD, TWD, TAD and TAMD 40-series industrial and marine diesel engines.

🔌 Function

The pulley transfers rotational drive from the engine's drive belt to the coolant pump, maintaining circulation of coolant through the engine and heat exchanger. Its grooved profile keeps the belt correctly seated and tensioned under load.

⚠️ Common Signs of Failure

• Belt squeal or chirping from the front of the engine
• Visible wear, grooving or corrosion in the belt tracks
• Wobble or run-out causing rapid belt edge wear
• Belt slippage leading to overheating or reduced coolant flow
• Cracks or damage around the hub and bolt holes

🛠️ Service Notes

• Inspect the belt running surfaces before fitting — a pulley with glazed, scored, pitted or rust-roughened grooves will chew through a new belt in very little running time
• Check that the pulley runs true and that its bearing or bush turns smoothly with no roughness or side play; fit a new belt whenever a pulley is changed
• Confirm that every pulley in the drive lies in the same plane and that the belt profile matches each groove — misalignment shows up as belt dust, squeal or a worn belt edge and will destroy a new belt quickly
• Fit onto a clean, dry, burr-free shaft or hub face and tighten the retaining fasteners in the sequence and to the figures given in the workshop manual for your engine
• Turn the engine over by hand before starting to confirm the belt is fully seated in every groove and that nothing fouls, then recheck belt tension after the first running period
