Large Bore Diesel Engine Piston, Slipper-Skirt Bowl-Type - Used

Large-Bore Diesel Engine Piston — Bowl-Type Crown, Slipper Skirt (Used)

Application: Not verified. This is a heavy-duty large-bore diesel piston with a deep toroidal combustion bowl, multiple ring grooves, and a relieved (slipper) skirt with ribbed pin-boss struts. No manufacturer name or OEM service number is visible on the part, so no engine family is claimed. May fit a large-bore industrial or marine diesel; buyer must confirm. Sold by photographs, visible markings, and dimensions.

Markings read on the part: "N 78" (stamped/cast on the skirt) and a faint "60" inside the skirt. These are treated as foundry/size markings, not orderable OEM part numbers.

Condition: Used take-off, untested and unmeasured (Grade C). Complete as a bare piston; piston pin, rings, retainers, and rod are not included. Light surface oxidation and shop soil present. Ring grooves, crown, and pin bore have not been gauged or crack-checked, so no serviceability claim is made. We are happy to supply crown diameter, pin bore, compression height, and groove measurements on request.

Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase. Used marine part sold as-is unless otherwise stated. No returns on electrical, used, special-order, or installed parts.
