CFMoto Hydraulic Tensioner

Part Number: 0SQV-024400-1001

🔧 Timing Tensioner · Valve Train · Engine Internal

OEM quality · Hydraulic auto-tension · Ensures proper timing chain/belt tension

This is a genuine CFMoto Hydraulic Tensioner, part number 0SQV-024400-1001. The hydraulic tensioner is a critical component of the engine valve train (timing system), typically used in timing chain systems. It utilizes engine oil pressure and internal spring force to automatically maintain proper tension on the timing chain, compensating for chain elongation due to wear and thermal expansion, ensuring accurate timing, smooth operation, and reducing chain vibration and noise. By replacing a worn, stuck, or leaking original hydraulic tensioner, proper timing system operation is restored, preventing serious engine failures such as chain jumping teeth or piston-to-valve interference.

This Hydraulic Tensioner fits the following CFMoto engines/models:

• OEM Quality: Manufactured strictly to original specifications, ensuring dimensions, oil passage design, and tension characteristics identical to the original part.
• Hydraulic Auto-Adjustment: Utilizes engine oil pressure to automatically and continuously maintain optimal timing chain tension.
• Built-in Check Valve: Internal check valve structure maintains plunger extended position, preventing chain slack.
• Precision Manufacturing: Precision fit between plunger and bore minimizes internal leakage, ensuring stable tension output.
• Direct Replacement: Perfect bolt-in fit when installed according to the factory service manual, restoring timing system performance and eliminating chain noise.

🛑 Importance of Hydraulic Tensioner

The hydraulic tensioner is a critical component in modern engine timing systems, especially in timing chain engines. Its primary function is to automatically maintain proper tension on the timing chain, compensating for minor elongation caused by wear and thermal expansion during operation. If the tensioner malfunctions (such as internal leakage, sticking, or spring fatigue), insufficient timing chain tension results, causing chain slap against guides and producing noticeable noise. More seriously, severely inadequate tension can lead to timing chain jumping teeth, causing the engine's valve timing to become misaligned. Pistons may then interfere with valves, resulting in bent valves, piston damage, and other catastrophic consequences requiring engine overhaul. Therefore, when timing chain noise occurs or during timing system service, inspecting and replacing the hydraulic tensioner is a critical step in ensuring engine reliability.

⚠️ Fitment Note: This product is Hydraulic Tensioner (0SQV-024400-1001). It fits 2023-2024 272MQ-F, 272MQ-B engines and 2023 CF400-6F(4) motorcycle. Before ordering, always verify your engine model and original part number. Please consult the service manual for proper compression and release procedures and ensure timing marks are aligned during installation.
