FAQ

1. How can I confirm this cylinder liner is the correct part for my engine?

Please verify the part number stamped on your existing cylinder liner or consult your engine’s parts manual. This product is a direct replacement for Komatsu part numbers 6115-21-2210 and 6115-21-2211. It is specifically designed for the 4D130 engine model.

2. Does this liner require any special installation procedures?

Installation should be performed by a qualified diesel mechanic. While it is a direct-fit OEM replacement, standard procedures apply. The engine block bore must be clean and free of debris. We recommend using a suitable lubricant on the liner’s outer O-ring or seal during installation to prevent damage. Always follow the engine manufacturer’s service manual for torque specifications and break-in procedures.

3. What is the expected lifespan of this cylinder liner under normal operating conditions?

The lifespan depends heavily on maintenance, operating environment, and load. However, due to its high-grade cast iron construction and precision hardening, this liner is designed to provide a long service life comparable to the OEM component. Regular oil changes, proper coolant maintenance, and air filter care will significantly extend the life of the liner and the entire engine.
