FAQ

Q: How can I be sure this piston (ME241686) will fit my Mitsubishi 4M51 engine?
A: The ME241686 is the standard OEM part number for the 4M51 piston assembly. To confirm fitment, we recommend checking the part number stamped on the top of your current piston or in your engine service manual. This part is designed to OEM specifications, making it a direct replacement for the original component.

Q: Does this assembly include the piston rings, or just the piston and pin?
A: This specific product listing is for the piston and the piston pin only. Piston rings are typically sold separately or as part of a complete overhaul kit. We recommend ordering the corresponding piston rings (e.g., part number ME241687 or similar) to ensure a complete and proper rebuild.

Q: What is the recommended installation procedure for this piston?
A: Installation should be performed by a qualified diesel mechanic. Key steps include: cleaning the cylinder bore, lubricating the piston and rings (if using new rings), compressing the rings with a proper ring compressor, and carefully tapping the piston into the bore using a wooden or plastic handle. Always torque the connecting rod bolts to the manufacturer’s specified settings. Refer to the Mitsubishi 4M51 service manual for the exact procedure and torque values.
