11030505 Pulley | Genuine Volvo Penta Part

🔧 Product Description

This is a genuine Volvo Penta pulley from the cooling system group, supplied in the 140 mm diameter (D=140mm) size. It transfers drive from the engine's belt system to turn the coolant circulation pump, and the 140 mm outer diameter is what separates it from otherwise similarly named pulleys, so confirm the diameter before ordering. It is listed for the TD, TID and TWD 60- and 70-series marine and industrial diesel engines.

🚤 Compatibility

• Engine Family: TWD, TID, TD
• HP Range: Approximately 160-250 HP
• Year Range: Approximately 1990s - 2010s

🔌 Function

The pulley is driven by the engine belt and turns the coolant pump so circulation is maintained through the engine and heat exchanger. Correct pulley diameter sets the drive ratio and therefore the coolant pump speed.

⚠️ Common Signs of Failure

• Squealing or chirping from the belt drive area
• Visible wear, grooving or chipping in the belt grooves
• Wobble or run-out causing rapid belt wear or belt throwing
• Rust, corrosion or scoring on the pulley face
• Coolant temperature rising due to slipping drive and reduced pump speed

🛠️ 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
