If your 6D95 engine is emitting blue smoke and showing high crankcase pressure, the 6207-31-2180 piston rings or the piston lands themselves may be worn. Inspect for vertical scoring on the cylinder liner which indicates piston skirt collapse.
Replacing only one piston is a temporary fix. For long-term reliability in machines like the Komatsu PC200, we recommend a complete set of six pistons, liners, and rings to ensure balanced compression across all cylinders.
Question: Why should I choose your 6207-31-2180 over local market options?
Answer: Our pistons feature an OEM-standard tri-metal structure and are trusted by repair shops & equipment fleets globally for their dimensional stability and heat resistance under extreme hydraulic loads.
