FAQ

Q: How can I confirm this piston will fit my specific Kubota engine?
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 listed numbers: 1G701-21112, 1A021-21112, or OEM 07916-26230. Always confirm your engine model is D1503 or V2003.

Q: Is this piston sold as a single unit or as a set?
A> This piston is sold as a single item. For a complete engine overhaul, you will typically need to purchase a set equal to the number of cylinders in your engine (e.g., 3 pistons for a 3-cylinder D1503). Please order the required quantity.

Q: What should I check during installation to ensure proper performance?
A> Critical steps include: 1) Measuring the cylinder bore and piston skirt clearance as specified in the service manual. 2) Ensuring piston rings are correctly gapped and installed in the proper orientation. 3) Lubricating the piston skirt and rings with engine oil during assembly. We recommend installation by a qualified mechanic familiar with diesel engine rebuilding.
