FAQ

Q: How do I confirm this piston ring set fits my engine?
A: Check your engine’s model plate to ensure it is a Mitsubishi 4DQ5. Then, compare your existing piston ring diameter and thickness with the OEM size specifications. The reference number 30617-51011 should match your old part. If you are unsure, please contact us with your engine serial number for verification.

Q: What is the recommended installation procedure?
A: Installation should be performed by a qualified diesel mechanic. Ensure the cylinder bore is clean and within service limits. When installing, stagger the ring gaps (typically 120 degrees apart) to prevent gas blow-by. Lubricate the rings and piston with clean engine oil before assembly. Always follow the engine manufacturer’s service manual for torque specifications.

Q: How should I store these piston rings if I am not installing them immediately?
A: Store the piston rings in a cool, dry environment away from direct sunlight and moisture. Keep them in their original packaging to prevent damage or corrosion. Avoid exposure to chemicals or solvents. Proper storage will ensure the rings remain in optimal condition for future use.
