FAQ

Q1: How do I confirm this cylinder liner fits my specific Komatsu engine?
A1: The surest method is to cross-reference the part number stamped on your original liner or listed in your engine’s service manual. This part (6162-23-2210) is designed for the S6D170, 6D170, and SA6D170E engine families. Providing your engine model and serial number to our technical team allows us to verify compatibility.

Q2: What is the difference between a cylinder liner and a cylinder sleeve?
A2: In this context, the terms “liner” and “sleeve” are interchangeable for heavy-duty diesel engines. It is a removable cylindrical insert that forms the inner wall of the engine cylinder, providing a wear surface for the piston rings and allowing for rebuilds without replacing the entire engine block.

Q3: Are installation instructions or technical specifications provided?
A3> While detailed installation procedures should be followed from the official Komatsu service manual, we can provide critical dimensional data (e.g., inner diameter, outer diameter, height) upon request. Proper installation, including correct bore preparation and liner protrusion measurement, is essential for engine performance and longevity.
