CFMoto 2V91Y-F Piston

Part Number: 0JYV-040002-5000-Q0-00002

Product Type: Engine Piston | Individual Piston

Fitment: CFMoto 1000cc ATV (2V91Y-F Series)

OEM-specification 2V91Y-F piston, manufactured from high-strength aluminum alloy with precision machining, ensuring perfect fit with the cylinder and maintaining engine compression ratio and power output. Suitable for engine overhaul or piston replacement.

📋 Product Overview

This product is a genuine quality CFMoto 2V91Y-F Piston, part number 0JYV-040002-5000-Q0-00002. This piston is manufactured from high-strength aluminum alloy through precision casting and machining, offering excellent strength, wear resistance, and thermal conductivity.

The piston is the core reciprocating component of the engine, bearing the high temperatures and pressures of combustion and converting them into mechanical energy. The piston crown design, skirt shape, and ring groove positions are precisely calculated to ensure optimal combustion efficiency and minimal friction loss. The piston-to-cylinder wall clearance is critical, directly affecting engine performance, fuel consumption, and service life.

🔧 Genuine Quality Assurance: Manufactured strictly according to CFMoto OEM technical standards. Dimensions, material quality, and machining precision are identical to the original parts, ensuring perfect fitment and reliable durability.

📌 Fitment Note: This 2V91Y-F Piston (Part Number 0JYV-040002-5000-Q0-00002) fits all CFMoto 1000cc ATV models listed above. Please verify your specific model is listed before purchasing. If your model is not listed, please contact our customer service with your VIN for confirmation.

⚙️ Product Functions

Withstands Combustion Pressure: The piston crown directly bears 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 bearing side forces.

✅ Fault Indications: Common signs of piston wear or 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 promptly.

✅ Installation Tip: Thoroughly clean the cylinder and piston before installation. When installing piston rings,attantion ring orientation and gap positioning. Carefully install the piston pin and circlips, ensuring circlips are fully seated in their grooves. 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.
