Engine Piston Set with Pin and Circlips
Restore factory compression, quiet operation, and clean exhaust with this OEM-grade piston set (OE ref: 230412U900). It’s designed for precise fit and balance, bringing back power, fuel economy, and smooth cold starts. Ideal when the engine shows piston slap, oil burning, or low compression after high mileage or overheating.
How it works ⚙️
The lightweight aluminum piston moves up and down in the cylinder, sealing combustion with its rings. The wrist pin lets the connecting rod pivot smoothly, while circlips lock the pin in place. Graphite-coated skirts reduce friction; oil drain ports control oil on the wall for clean burn and stable temperatures.
When worn or broken
Expect hard starts, misfires, blue smoke, high oil use, rattling on cold start, and loss of power. Severe damage can scratch the bore, contaminate oil with metal, ruin the catalyst, or even seize the engine.
Tech highlights ️
Correct OE geometry and weight class for balance, heat-treated pin, precise circlip retention, and ring seats for stable compression. Always measure bore, hone for crosshatch, set ring gaps, and align “FRONT” mark. Use fresh oil and gaskets on install.
