🔧 Product Description

🔌 Function

Takes the drive belt and turns it into rotation of the shaft it is fitted to, driving the charging system at the ratio set by its diameter.

⚠️ Common Signs of Failure

• Belt squeal on start-up or under load
• Belt dust, glazing or black powder around the drive
• Groove worn wide, polished or stepped
• Pulley running out of true or wobbling visibly
• Charging output dropping off because the belt is slipping

🛠️ Service Notes

• Fit a new belt with the pulley — a worn groove will have taken the edge off the old one
• Check the alignment of the whole drive before tensioning, as a mis-aligned pulley will eat the new belt too
• Both Std pulleys here are 873343 and 873344; confirm which your engine is listed under before ordering
