CFMoto Piston Pin Circlip

Part Number: 0NYV-040006-1000

🔧 Piston Pin Circlip · Engine Internal · OEM Quality

2 required per piston · Spring Steel · Precision Size

📋 Product Overview

This is a genuine CFMoto Piston Pin Circlip, part number 0NYV-040006-1000. The piston pin circlip is a critical small fastener in the engine piston assembly. It is installed in the grooves at both ends of the piston pin bore to axially secure the piston pin, preventing it from sliding out during operation and scratching the cylinder wall. These circlips are made from specialized spring steel, providing the correct elasticity and fatigue strength to ensure reliable retention under high-temperature, high-speed reciprocating motion. During engine overhaul or piston ring replacement, new circlips must always be used. Never reuse old circlips, as loss of tension can lead to severe engine damage.

✨ Product Type: Piston Pin Circlip / Piston Pin Retaining Ring

✨ Part Number: 0NYV-040006-1000

✨ Installation Location: Both ends of piston pin bore (engine internal)

✨ Quantity per Engine: 2 per piston (exact number depends on cylinder count)

📌 Important Note: This product is the CFMoto Piston Pin Circlip (Part Number 0NYV-040006-1000). The compatibility list above is based on the data you provided. This circlip primarily fits SSV series with the 380Y-2A engine (Z10/Z10-4) and UTV series with the 380Y-3 engine (UForce / U10). Piston pin circlips are wear items that must be replaced during engine overhaul. Each piston requires two circlips. If your model is not listed, please verify your original part number or engine model, or contact our support team to confirm compatibility.

⚙️ Product Features
  • OEM Specifications: Manufactured precisely according to CFMoto original drawings. Wire diameter, free outer diameter, and gap dimensions exactly match the piston pin groove.
  • High-Quality Spring Steel: Made from specialized spring steel, offering excellent elastic limit and fatigue resistance to ensure reliable retention throughout the engine's service life.
  • Surface Treatment: Typically black oxide or phosphate coated for basic corrosion resistance while maintaining proper friction characteristics.
  • Single Use Only: Circlips undergo plastic deformation during installation, which reduces their tension. It is strongly recommended to always install new circlips whenever the piston pin is removed.

🛑 Severe Consequences of Circlip Failure

Though small, the piston pin circlip plays a vital role. If a circlip fatigues, breaks, or loses tension and falls out, the piston pin will slide axially and directly contact the cylinder wall, causing severe scoring (cylinder wall damage). This leads to loss of compression, increased oil consumption, engine noise, and may ultimately require cylinder boring or replacement of the cylinder block and piston assembly—a very costly repair. Never reuse old circlips to save a small cost during an engine overhaul. Using new OEM circlips is the most basic protection for your engine.

⚠️ Installation Note: Piston pin circlips should be installed using专用 circlip pliers. After installation, verify that the circlip is fully seated in the groove and properly engaged. The gap opening should be positioned away from the high-stress area of the piston pin bore (typically oriented as specified in the service manual, away from the pin bore cutout). Improper installation can deform the circlip or lead to dislodgment. We recommend installation by an experienced technician.
