FAQ

Q1: How do I confirm this XC490BPG kit fits my engine?
A: Please verify your engine’s model number (stamped on the engine nameplate). This kit is specifically for the Xinchai XC490BPG model. If your engine is a different variant (e.g., 490B, 490Q), please send us your engine serial number or old part number for cross-referencing. We also recommend measuring the cylinder bore diameter (standard 90mm) and piston pin height before ordering.

Q2: What is included in the kit, and is installation difficult?
A: The kit typically includes cylinder liners, pistons, piston rings, and piston pins. Installation should be performed by a qualified diesel mechanic. Proper procedures include cleaning the engine block, checking liner protrusion, and ensuring ring gap alignment. We provide installation guidelines with each order. For professional rebuilders, we recommend using a torque wrench and following Xinchai’s service manual specifications.

Q3: What is the expected lifespan of this cylinder liner kit?
A: Under normal operating conditions with proper maintenance (regular oil changes, clean fuel, and proper cooling), this kit can last 8,000-12,000 hours. Actual lifespan depends on factors such as load, operating environment, and maintenance schedule. For marine or high-load applications, more frequent inspections are recommended. We advise replacing piston rings at the first sign of increased oil consumption or blow-by.
