FAQ

Q: How can I confirm this piston is the correct part for my Doosan excavator?
A: The most reliable method is to cross-reference the part number stamped on your original piston or listed in your engine’s service manual with our part number 65.02501-0773. Also, verify your engine model (D2366) and series (De12).

Q: Is this piston sold as a single unit or as part of a set?
A: This listing is for a single cylinder piston. For a complete engine overhaul, we recommend replacing all pistons and rings as a set to ensure balanced performance. Contact us for set pricing and availability.
