FAQ

Q: Is this piston ring set complete for a full 6HH1 engine overhaul?
A: This listing is for the specific piston ring part number 8-94390799-0. Typically, this is a single ring or a set for one piston. For a full 6-cylinder engine overhaul, you will need to order 6 sets (quantity 6). Please confirm your engine’s requirements, as some applications may require different ring combinations for different piston grooves.

Q: Will this piston ring fit my excavator model?
A: This ring is designed for the Isuzu 6HH1 engine. While many excavators use this engine, the specific chassis model (e.g., Hitachi, Sumitomo, Kobelco) does not determine fitment. You must verify that your machine’s engine is a 6HH1. Check the engine data plate for the model stamping. If your engine is a 6HH1, this ring is the correct genuine component.

Q: What maintenance is recommended after installing new piston rings?
A: After replacing piston rings in a 6HH1 engine, a proper break-in procedure is critical. This typically involves running the engine at varying loads without excessive idling for the first 50-100 hours. Ensure the cylinder bores are properly honed and that the ring end gaps are checked during installation. Use the recommended oil viscosity for the 6HH1 and change the oil and filter after the initial break-in period to remove any wear particles.
