FAQ

Q: How can I confirm this piston (6246-31-2110) fits my Komatsu engine?
A: Please verify your engine model is a Komatsu 6D170. For absolute certainty, cross-reference the part number stamped on your existing piston or your engine’s service manual with the OEM number 6246-31-2110. If you have a different engine model, please contact us with your engine serial number for compatibility checking.

Q: What is the recommended installation procedure for this piston?
A: Installation should be performed by a qualified diesel mechanic. Ensure the cylinder bore is within specification and properly honed. Always use new piston rings and lubricate the piston skirt and rings during assembly. Follow the torque specifications and sequence provided in the engine’s official service manual for the connecting rod bolts.

Q: What is the standard size of this piston, and does it require special tools?
A: This is an OEM standard size piston. No special oversized or undersized machining is required if the cylinder bore is in good condition. However, a piston ring compressor and a torque wrench are essential for proper installation. We recommend checking the piston-to-wall clearance with a feeler gauge to ensure it falls within the manufacturer’s specifications.
