FAQ

Q1: How can I confirm that this Cylinder Liner Kit (6136-21-2210) will fit my engine?
A: Please check the identification plate on your engine block to confirm the model is the Komatsu 4D105-5. Additionally, compare the part number stamped on your old liner with our listed numbers (6136-21-2210 or 6136-31-2030). This is the most reliable method to ensure a correct fit.

Q2: What is the recommended installation procedure for these liners?
A: Installation should be performed by a qualified diesel mechanic. The cylinder bore must be thoroughly cleaned and inspected for damage. The new liner should be installed using a suitable press tool to avoid distortion. After installation, check the liner protrusion height to ensure it is within the engine manufacturer’s specifications before reassembling the cylinder head.

Q3: What are the common signs that this cylinder liner needs replacement?
A: Key indicators include excessive blue or white smoke from the exhaust, high oil consumption, loss of engine compression (detected during a compression test), and audible knocking sounds from the engine block. If you are performing a full engine overhaul, it is standard practice to replace the liners, pistons, and rings simultaneously.
