Timing Chain Tensioner – For Speedstar Quad Jinling Racing ATV 300 JLA-931E

Timing Chain Tensioner – For Speedstar Quad Jinling Racing ATV 300 (JLA-931E)

Precise Timing – Ensures Optimal Chain Tension and Smooth Engine Running!

The chain tensioner is an essential component of engine management. It automatically ensures the correct tension of the timing chain to prevent the chain from skipping and faulty valve timing. A defective or worn chain tensioner leads to loud rattling noises (especially at idle), rough engine running, and in the worst case, engine damage due to incorrectly set timing.

This Chain Tensioner is a precise replacement part and was specially developed for the engine of the Speedstar Quad Jinling Racing ATV 300 (Model JLA-931E).

Product Details and Benefits

• Automatic Tensioning: Precisely maintains the correct tension of the timing chain.

• Reduces Noise: Eliminates the rattling of a loose chain.

• Secures Timing: Prevents the chain from skipping.

• Precise Fit: Specifically for the Jinling 300cc engine.

Important Note on Verification and Compatibility

Chain tensioners are precision-manufactured parts. Accurate verification of the design and the operating principle (hydraulic/mechanical) is essential. Please visually compare the item with your old part. Also, please pay attention to all article information such as the dimensions, the shape of the mounting plate, and the position of the tensioner piston, to ensure the correct fit and function.

Installation Instructions (Intended as Guidance Only!)

Important Note: Replacing a chain tensioner is critical for engine function. Before installation, the engine must be set to Top Dead Center (TDC) and the valve timing must be checked and secured before the new tensioner is activated. The following guide is intended only as assistance.

1. Preparation: Secure the quad and turn off the engine. Set the engine to TDC (Top Dead Center).

2. Disassembly: Remove the old chain tensioner (usually two screws). Be careful not to drop any parts into the engine.

3. Replacement: Insert the new chain tensioner (in the tensioned/secured position) and fasten it securely according to the manufacturer's specifications.

4. Activation and Check: Release the lock of the new tensioner so that it tensions the chain. Carefully turn the engine over by hand to check the function and timing.

Ensure the precision of your engine's timing! Order the Timing Chain Tensioner (Art. No. 055-101303)!
