FAQ

Q1: How do I confirm that this cylinder liner will fit my engine?
The most reliable way to confirm fitment is to check the part number stamped on your old cylinder liner or in your engine’s service manual. If it matches 6110-21-2212 or 6110-21-2210 and your engine model is a Komatsu 4D120, then this part is the correct replacement. If you are unsure, please contact our support team with your engine serial number.

Q2: What is the recommended installation procedure for this cylinder liner?
Installation should be performed by a qualified diesel mechanic. The cylinder block bore must be clean and free of debris. The new liner should be carefully pressed or driven into place using a proper installation tool to avoid damage. It is highly recommended to check the liner protrusion above the block deck to ensure it meets the engine manufacturer’s specifications.

Q3: Can I replace just one cylinder liner, or should I replace all four?
While it is possible to replace a single damaged liner, it is generally recommended to replace all liners and piston rings in the engine during an overhaul. This ensures uniform wear, consistent compression across all cylinders, and optimal engine balance. If the other liners show minimal wear, a single replacement is acceptable, but a full set is always the best practice for long-term reliability.
