FAQ

Q1: How do I confirm this is the correct cylinder liner for my specific Mitsubishi engine?
A1: The most reliable method is to match the part number. Locate the original liner or consult your engine’s parts manual for the OEM number (ME011604, ME011523, or ME011626). Also, verify your engine model (4D31 or 6D31) and measure the old liner’s dimensions if the part number is not visible.

Q2: What is typically included in the installation process for a cylinder liner?
A2: Professional installation is recommended. The process generally involves: 1) Complete engine disassembly and removal of the old liner, 2) Thorough cleaning and inspection of the engine block’s counterbore, 3) Precise measurement of liner protrusion, 4) Proper fitting of the new liner (which may require heating the block or cooling the liner), and 5) Final honing after installation to achieve the correct piston clearance.

Q3: Do you supply matching piston and ring sets for a complete cylinder kit?
A3: Yes, we often supply complementary components for a full engine overhaul. We recommend replacing pistons, rings, and connecting rod bearings concurrently with cylinder liners for a balanced rebuild. Please inquire for kit availability for the 4D31/6D31 engine series to discuss volume pricing.
