FAQ

Q: How do I verify this piston ring set fits my engine?
A: Confirm the OEM part number (8-98023-526-0) matches the ring set removed from your engine. Also check your engine model (4HK1 or 6WG1) and year of manufacture. For Hitachi excavators, cross-reference your machine’s serial number with the engine model.

Q: Can I install these rings without replacing the cylinder liner?
A: It is strongly recommended to inspect the cylinder liner for wear, scoring, or ovality. If the liner is worn beyond service limits, it should be replaced to ensure proper ring seating and compression. Always follow the engine manufacturer’s service manual.

Q: What is the recommended break-in procedure for new piston rings?
A: After installation, operate the engine under varying loads (avoid sustained idle or full load) for the first 10-15 hours. Use the recommended engine oil grade and change it after the break-in period to remove initial wear debris. Avoid high-RPM operation until the rings have properly seated.
