Chain Tensioner

CFMoto Chain Tensioner

OEM Part Number 0JWV-024400-3002

🔧 Timing Chain Tensioner · Engine Valve Train

OEM quality · Direct replacement · Ensures proper timing chain tension

This is a genuine OEM-spec CFMoto Chain Tensioner (Timing Chain Tensioner), part number 0JWV-024400-3002. The timing chain tensioner is a critical component of the engine's valve train. It uses spring or hydraulic pressure to automatically maintain the correct tension on the timing chain, preventing slack and ensuring accurate valve timing. This direct replacement part eliminates chain noise and prevents serious engine damage caused by timing slippage. Fits various CFMoto ATV and UTV models.

This Chain Tensioner (0JWV-024400-3002) fits the following CFMoto models:

• OEM OE Quality: Manufactured to original specifications, ensuring identical performance and durability.
• Automatic Tensioning: Internal spring or hydraulic mechanism automatically adjusts tension to compensate for chain wear, maintaining optimal tension at all times.
• Noise Reduction: Effectively eliminates "clattering" noises caused by a loose timing chain, ensuring quieter engine operation.
• Prevents Skipping: Ensures proper engagement of the timing chain with sprockets, preventing chain slip and timing errors.
• Direct Replacement: Designed for bolt-on installation with a perfect fit inside the engine – no modifications required.
• Protects Engine: Accurate timing is fundamental to engine operation; the tensioner is a critical component for preventing catastrophic engine damage.

🛑 The Importance of the Timing Chain Tensioner

The timing chain tensioner is a vital component for maintaining correct engine timing. It maintains constant tension on the timing chain, compensating for wear and elongation over time. A failed tensioner allows the chain to become loose, causing noise and potentially allowing the chain to skip teeth on the sprockets. If the timing chain jumps, the valve and piston timing becomes desynchronized, which can lead to bent valves, piston damage, and complete engine failure. Regularly inspecting and replacing the timing chain tensioner as needed is essential preventive maintenance to avoid catastrophic engine damage and ensure long-term reliability.

⚠️ Fitment Note: This part is the Chain Tensioner, part #0JWV-024400-3002. It fits CFMoto 800/850/1000cc ATV and UTV models (2V91W-F, 2V91Y-F, 2V91W-K engines). Always verify your original part number before ordering.
