📌 Fitment Note: This Piston Assembly (Part Number 0JYA-0400A0) fits all CFMoto 400cc-1000cc ATV, SSV, and UTV models listed above. Please observe the front and rear cylinder installation direction requirements. Piston marks I and II are interchangeable. If your specific model is not listed, please contact our customer service with your VIN for confirmation.

⚙️ Product Functions

Withstands Combustion Pressure: The piston crown directly承受s the high temperatures and pressures of combustion, converting them into mechanical energy.
Reciprocating Motion: Performs high-speed reciprocating motion within the cylinder, driving the crankshaft through the connecting rod.
Seals Combustion Chamber: Works with piston rings to seal the combustion chamber, preventing gas leakage.
Transfers Heat: Transfers most of the combustion heat to the cylinder wall, where it is carried away by the cooling system.
Guides Motion: The piston skirt contacts the cylinder wall, guiding smooth piston motion and承受ing side forces.

✅ Fault Indications: Common signs of piston or piston ring wear/damage include:
• Engine burning oil, blue smoke from exhaust;
• Loss of power, low compression;
• Engine knocking noise;
• Excessive oil consumption;
• Heavy carbon deposits on spark plugs.
If you encounter these issues, inspect and replace the piston assembly promptly.

✅ Installation Tip: Thoroughly clean the cylinder and piston before installation. When installing piston rings,注意 ring orientation and gap positioning, with gaps staggered. Carefully install the piston pin and circlips, ensuring circlips are fully seated in their grooves. Pay attention to front and rear cylinder installation direction requirements. Use a ring compressor when installing the piston into the cylinder to avoid damaging the cylinder wall. Professional installation by an experienced technician is highly recommended.
