Pistón

Start with your engine manufacturer, complete engine model, and original piston part number. If available, also check the engine serial number and the dimensions specified in your service documentation. Compare these details with the replacement piston listing rather than relying on the equipment model alone. If you are unsure which piston matches your engine, send us your engine information and original part number for assistance.

An individual replacement piston listing may include only the piston, while a piston kit can include additional components such as a piston pin, retaining clips, or piston rings. Some of our listings also offer multi-piece sets for engines with multiple cylinders. Contents vary by product, so please check the listing carefully to confirm what is included before ordering.

An oversize piston should only be selected when the engine's cylinder bore has been measured and prepared for the corresponding size according to the manufacturer's specifications. It is not a direct substitute for a standard-size piston. Before ordering, confirm the required bore diameter, piston clearance, and machining requirements with your engine technician or service documentation.

The correct size depends on the engine's cylinder bore condition and the repair specifications. An oversize piston may be required after a cylinder is machined to a larger diameter, but the correct oversize must be determined from the engine's service specifications and measured bore. Do not select an oversize piston based on the engine model alone.
