FAQ

Q1: How do I confirm this piston fits my specific Mitsubishi engine?
A: Please verify your engine model (K3M or K4M) and check the part number on your current piston. If it matches 77014-74856, it is a direct fit. For further confirmation, you can provide your engine serial number to our support team.

Q2: Is the piston pin included, and is it pre-lubricated?
A: Yes, the piston pin is included as part of this assembly. The pin is not pre-lubricated; we recommend applying fresh engine oil to the pin and piston bore during installation to ensure proper initial lubrication and prevent scoring.

Q3: What is the recommended installation procedure for this piston?
A: Installation should be performed by a qualified technician. Ensure the cylinder bore is clean and within specifications. Use a piston ring compressor to install the piston into the cylinder, and torque the connecting rod bolts to the manufacturer’s specifications. Always replace piston rings and cylinder liners if worn for optimal performance.
