FAQ

Q1: How do I verify if this K4N Cylinder Liner (30H94-01040) fits my engine?
A: Please check the engine model plate on your equipment. It should clearly state “K4N”. Additionally, compare the part number on your old liner (30H94-01040) with the one listed. If you are unsure, measure the liner’s outer diameter, inner diameter, and length, and contact us with those dimensions for confirmation.

Q2: What is the recommended installation procedure for a new cylinder liner?
A: Installation should be performed by a qualified diesel mechanic. Key steps include: cleaning the cylinder block bore, checking the liner protrusion height, applying a suitable sealant (if required), and using a liner press to avoid distortion. After installation, a light hone may be needed to ensure correct ring seating. Always refer to the Mitsubishi K4N service manual for torque specifications and procedures.

Q3: How can I extend the service life of my new cylinder liner?
A: Regular maintenance is key. Use high-quality engine oil and change it at the recommended intervals. Ensure the coolant system is properly maintained with the correct coolant mixture to prevent cavitation. Avoid operating the engine under heavy load before it has reached normal operating temperature. Finally, always use clean fuel and replace air and fuel filters as scheduled to prevent abrasive particles from entering the cylinder.
