FAQ

Q1: How can I confirm this cylinder liner fits my Mitsubishi S4L engine?
A: Verify the engine model stamped on your engine block (S3L, S4L, or S4L2). Then check the existing cylinder liner for the part number 34407-05400 or Me012657. Measure the liner’s outer diameter, inner diameter, and overall height to confirm match with OEM specifications. If unsure, contact us with your engine serial number for verification.

Q2: What is the recommended installation procedure for this cylinder liner?
A: Installation should be performed by a qualified diesel mechanic. Clean the engine block bore thoroughly. Apply appropriate lubricant to the liner’s outer surface. Use a suitable installation tool to press the liner evenly into the block, ensuring it seats flush with the block deck. Check for proper protrusion height. Always follow the engine manufacturer’s service manual for torque specifications and procedures.

Q3: What maintenance practices extend the life of the cylinder liner?
A: Regular oil changes using the correct viscosity grade are critical. Maintain proper coolant levels and use quality antifreeze to prevent corrosion. Replace air filters on schedule to reduce abrasive particle ingress. Monitor engine operating temperature to avoid overheating, which can cause liner distortion. During overhauls, always inspect the liner for wear, scoring, or cracks.
