FAQ

Q: How do I verify that this ring set is correct for my Doosan DX12 engine?

A: Please cross-reference your engine’s serial number with the OEM part numbers 401004-00226 or 401004-00253S. Also, confirm the cylinder bore diameter. If your engine has been rebored, you may require an oversize ring set. Contact our technical support for assistance with identification.

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

A: Installation requires a professional ring expander tool to prevent breakage. Ensure the cylinder bore is clean, deglazed, and within spec. Stagger the ring gaps at 120-degree intervals around the piston. Lubricate the rings and piston with clean engine oil before installation. Always follow the Doosan service manual for torque specifications.

Q: Can these rings reduce oil consumption on my DX12Ti engine?

A: Yes, a worn piston ring set is the primary cause of high oil consumption. This OEM-spec replacement set features an advanced oil ring design that effectively scrapes excess oil from the cylinder walls, significantly reducing oil consumption and blow-by, thereby restoring engine efficiency.
