FAQ

Q: How do I verify if this piston ring set fits my specific engine?

A: The most reliable method is to check the engine model tag on your equipment. If it states “Mitsubishi 6DB10”, this ring set is designed for it. Additionally, compare the physical dimensions (diameter, thickness, and profile) of your old piston rings against the new set. The part number Sjm30005zz is a standard NPR reference for this engine.

Q: What is the recommended installation procedure for these piston rings?

A: Professional installation is recommended. Ensure the cylinder bore is within service limits and properly honed. Use a piston ring expander to avoid distorting the rings. Install rings in the correct order (oil ring first, then compression rings) and stagger the ring end gaps 120 degrees apart. Lubricate the rings and piston with clean engine oil before inserting into the cylinder.

Q: What is the difference between OEM size and oversized rings?

A: This product is listed as “OEM Size” (Standard Size). This is suitable for engine blocks with standard bore diameters that have not been over-bored. If your cylinder block has been machined to a larger diameter (e.g., 0.25mm, 0.50mm oversize), you will need a different part number. Always measure your cylinder bore before ordering.
