FAQ

Q1: How do I confirm this piston is the correct part for my Xinchai engine?
A1: The most reliable method is to match the part number from your engine’s official service manual or the markings on your current, worn piston. The engine model (YSD490Q) must match. Providing your engine’s serial number to our technical team can facilitate a final verification.

Q2: Is this sold as a single piston or as a full set for the engine?
A2> This listing is typically for a single piston assembly. For a complete engine overhaul, a full set matching the number of cylinders in your YSD490Q engine is required. Please contact us for pricing on full cylinder sets to ensure balanced performance.

Q3: What are the recommended installation procedures to ensure longevity?
A3> Professional installation is highly recommended. Key steps include: thoroughly cleaning the cylinder liner, checking ring end-gaps, properly lubricating the piston skirt and pin, and using a proper ring compressor tool. Always follow the engine manufacturer’s torque specifications and procedures for connecting rod bolts. Inspect and replace other wear items (liner, rings, bearings) as necessary during rebuild.
