FAQ

Q: Is this piston ring set compatible with the Komatsu S4D95 engine in my PC120 excavator?
A: Yes, this set is specifically designed for the S4D95 engine model. It is commonly used in PC60 and PC120 excavator series. We recommend double-checking your engine block casting number to confirm compatibility with OEM part 6204-31-2203.

Q: What is the recommended installation procedure for these rings?
A: Installation should follow standard diesel engine rebuilding practices. Ensure the cylinder bores are properly honed and cleaned. Use a piston ring expander tool to avoid breakage during fitting. Always stagger the ring end gaps according to the engine manufacturer’s specifications to prevent gas leakage.

Q: Do these rings require any break-in period after installation?
A: Yes, a proper break-in period is critical. After installation, run the engine at varying loads for the first 10-20 hours. Avoid prolonged idling or full-throttle operation immediately. Use high-quality diesel engine oil to ensure the rings seat correctly against the cylinder walls for optimal performance and longevity.
