FAQ

Q: How do I confirm this cylinder liner will fit my specific Komatsu engine?
A: The most reliable method is to match the part number stamped on your old liner. Cross-reference it with our listed numbers (6211-22-2220 or 6211-21-2210). Also, verify your engine’s model and serial number plate information against the compatible 6D140 series models listed.

Q: What precautions should be taken during installation?
A> Ensure the engine block counterbore is clean and free of debris or old sealant. Always use new sealing rings (O-rings) at the base of the liner. Follow proper torque sequences and specifications for cylinder head installation to avoid distorting the new liner. Proper coolant system bleeding is essential after installation.

Q: Do you offer OEM services or custom specifications?
A> Yes, we provide OEM manufacturing services. We can produce cylinder liners according to client-provided drawings, samples, or specific material specifications. Contact our sales team with your requirements for a customized quotation.
