Camshaft Timing Chain

CFMoto Camshaft Timing Chain

Part Number: 0NYV-024031-2000

🔧 Timing Chain · Valve Train · Engine Internal

OEM quality · High-strength wear-resistant · Ensures precise timing

This is a genuine CFMoto Camshaft Timing Chain, part number 0NYV-024031-2000. The timing chain is a core component of the engine valve train (timing system), responsible for connecting the crankshaft and camshaft, ensuring they maintain precise relative positions to open and close valves at the correct times. It consists of high-strength alloy steel links and rollers, designed to withstand millions of load cycles, offering long life and high reliability. By replacing a worn or stretched original timing chain, engine timing accuracy is restored, preventing valve timing deviation, power loss, increased noise, and severe engine damage caused by chain jumping teeth.

This Timing Chain fits the following CFMoto engine models:

• OEM Quality: Manufactured strictly to original specifications, ensuring link dimensions, pitch, and tensile strength identical to the original part.
• High-Strength Material: Made from high-quality alloy steel with precision heat treatment, offering excellent fatigue strength and wear resistance.
• Precision Manufacturing: Links and rollers precision stamped and assembled for smooth, low-noise operation.
• Durable & Reliable: Designed for engine-long life, requiring no maintenance under normal operating conditions.
• Direct Replacement: Perfect bolt-in fit when installed according to the factory service manual, restoring timing system accuracy.

🛑 Importance of Timing Chain

The timing chain is one of the engine's "lifelines," ensuring precise synchronization between the crankshaft and camshaft. This synchronization determines the timing of valve opening and closing, directly affecting power output, fuel economy, emissions, and running smoothness. With increasing mileage, the timing chain gradually stretches. When chain stretch exceeds allowable limits, valve timing deviation occurs, resulting in power loss, increased fuel consumption, and rough idle. More severely, excessive chain stretch or tensioner failure can cause the chain to jump teeth, leading to violent piston-to-valve collision, resulting in bent valves, piston damage, cylinder head cracks, and other catastrophic consequences requiring engine overhaul or replacement. Therefore, during engine overhaul or when timing chain noise occurs, inspecting and replacing a worn timing chain is a critical step in ensuring engine reliability.

⚠️ Fitment Note: This product is Timing Chain (0NYV-024031-2000). It fits 2025 380Y-2A and 2026 380Y-2C engines. Before ordering, always verify your engine model and year. Replacing the timing chain typically requires simultaneous replacement of the tensioner, guides, and related components, and strictly following the service manual to align timing marks.
