22212495 Pulley | Genuine Volvo Penta Part

🔧 Product Description

V-belt pulley used on the freshwater circulation pump of compact D1-13, D1-20, D1-30 and D2-40 marine engines. It aligns with the crankshaft and alternator pulleys and sets the pump speed.

⚙️ Key Features

• Machined to the original bore, groove profile and offset
• Maintains the specified belt line and accessory speed ratio
• Balanced for continuous engine-speed operation
• Designed for the matching hub, fasteners and belt section
• Model and to prevent belt misalignment

🔌 Function

Drives the freshwater circulation pump and maintains correct accessory-belt alignment.

⚠️ Common Signs of Failure

• Groove wear, glazing or belt dust
• Wobble, runout or loose hub fit
• Cracks around the hub or bolt holes
• Repeated belt tracking or tension problems
• Abnormal accessory-drive noise or vibration

🛠️ 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
