FAQ
Q: Is this piston assembly a direct replacement for the OEM part on my Hitachi ZX470-3? A: Yes, this 1-12112001-0 assembly is designed as a direct drop-in replacement for the original ISUZU part on the 6WG1 engine used in Hitachi ZX470-3 and ZX450-3 excavators. It matches OEM dimensions and material specifications.
Q: What other components should I replace when installing a new piston? A: We strongly recommend replacing the piston rings, cylinder liners, and connecting rod bearings simultaneously. This ensures optimal compression and prevents premature wear. Always use new gaskets and seals during reassembly.
Q: How do I verify the correct piston size for my engine? A: The 6WG1 engine uses standard size pistons. However, after engine wear, you may require oversize pistons (e.g., 0.50mm or 1.00mm). Measure your cylinder bore diameter. If it exceeds the standard limit, you will need an oversized piston and matching liner. Our standard part is for standard bore. Contact us for oversize options if needed.
