FAQ

Q: How do I confirm this cylinder liner kit fits my PC450-10 excavator?
A: First, locate your engine’s serial number or model plate. It should read “SAA6D125-7”. Then, cross-reference your old part number with the OEM number listed (6252-31-2110). If both match, this kit is the correct component for your engine.

Q: What is included in the “Cylinder Liner Kit”?
A: This kit typically includes the cylinder liner itself. For a complete engine overhaul, you may need to purchase additional components separately, such as piston rings, pistons, and gaskets. Please check the product specifications or contact us for a detailed list of included items.

Q: What is the recommended installation procedure for this liner?
A: Installation should be performed by a qualified diesel mechanic. The liner bore must be clean and free of debris. It is critical to check the liner protrusion above the engine block surface using a dial gauge, as incorrect protrusion can lead to head gasket failure. Always use new O-rings and follow the engine manufacturer’s service manual for torque specifications.
