FAQ

Q: Will this ring set fit my Isuzu 6BG1 engine from a different excavator brand?

A: This set is specifically designed for the 105mm bore of the 6BG1 engine. While it is commonly used for the Hitachi ZAX200-6, the 6BG1 engine was also used in other models (e.g., Sumitomo, Kobelco). You must verify your engine model is 6BG1 and that the cylinder bore diameter is 105mm. If your engine is a 6BG1T (turbo) or has a different bore size, this set will not be compatible.

Q: What is included in this “set”? Does it cover all pistons?

A: This is a set for one piston. It includes the top compression ring, second compression ring, and the oil control ring assembly. If you are rebuilding a 6-cylinder engine, you will need to purchase 6 sets (one per cylinder). Please check the quantity in your cart before ordering.

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

A: Proper installation is critical. Always use a piston ring expander tool to avoid distorting the rings. Ensure the cylinder liner is clean and within specification. When installing the piston into the bore, stagger the ring gaps (typically 120 degrees apart) to prevent blow-by. Lubricate the rings and cylinder bore with clean engine oil prior to assembly. We recommend consulting the service manual for your specific engine for exact torque specifications and gap clearances.
