FAQ

Q1: Is this piston a direct fit for my Xinchai YSD490Q engine?

A: Yes, this piston is designed as a direct replacement for the Xinchai YSD490Q engine. It matches the OEM specifications for diameter, compression height, and pin size. We recommend checking your existing piston part number (e.g., YSD490Q-1004011) to confirm compatibility before purchase.

Q2: What maintenance should I perform when replacing the piston?

A: When replacing the piston, it is highly recommended to also replace the piston rings, piston pin, and cylinder liner (if worn). The cylinder bore should be inspected for wear, scoring, or out-of-round conditions. If the bore is worn beyond tolerance, it may need to be honed or re-bored to accept an oversize piston. Always use new gaskets and seals during reassembly.

Q3: Do you offer oversize pistons for rebored cylinders?

A: Yes, we typically offer oversize (0.50mm, 1.00mm) options for the Xinchai YSD490Q piston. If you require an oversize piston, please contact our sales team with your specific requirements so we can confirm availability and provide the correct part for your application.
