## ⚠️ Common Signs of Failure

-   Knocking from excessive pin or small-end clearance
-   Scoring, bluing or pitting on the pin surface
-   Oval or damaged piston-pin bore
-   Metal debris in the engine oil
-   Broken or displaced retaining snap ring

## 🛠️ Service Notes

-   Measure before assembling: pin, piston bore and rod bush must all be checked against the wear limits in the workshop manual for your engine, and a pin that has picked up or lost its finish is scrap
-   Assemble spotlessly clean and generously oiled with clean engine oil or the specified assembly lubricant; a dry pin galls on the first turn of the engine
-   Confirm piston and rod are the correct way round and correctly paired before the pin goes in
-   Where the manual specifies a warm fit, warm the piston evenly by the method it sets out and push the pin home in one movement — never drive a pin in with a hammer
-   Fit new circlips or retaining rings, compress them no more than needed to enter the bore, seat them squarely in the groove, and check each is fully home and cannot be rotated by finger pressure
