Transmission Shaft (Output/Main Shaft) – For Speedstar Quad Jinling Racing ATV 300 (JLA-931E)

Precise Power Transmission – Transfers Engine Power to the Rear Wheel Drive!

The transmission shaft (typically the output shaft on which the drive sprocket sits) is a highly stressed component inside the engine. It transmits the rotation and torque from the gearbox output to the chain drive. Defects on the shaft, such as worn splines, broken keys, or damaged bearings, lead to power loss, noise, or a total failure of power transmission.

This Transmission Shaft is a precise replacement, manufactured for the high loads in the 300cc engine and suitable for:

• Speedstar Quad Jinling Racing ATV 300 (Model JLA-931E)

Product Details and Benefits

• Stable Power Transfer: Ensures reliable transmission of torque and power.

• Precise Splines: Ensures a correct fit for the drive sprocket.

• High Material Strength: Manufactured for the dynamic loads within the gearbox.

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

Important Note on Verification and Compatibility

Since transmission shafts are deeply installed in the engine, accurate verification of the dimensions and the spline shape (number of teeth) is essential. Please visually compare the item with your old part. Also, pay attention to all article information such as the total length, diameter, and the number of teeth for the sprocket and the internal gear wheels, to ensure correct function within the gearbox block. It is recommended to use new oil seals and bearings during assembly.

Installation Instructions (Intended as Guidance Only!)

Important Note: Replacing a transmission shaft is a very complex engine repair that requires the complete disassembly of the engine casing (splitting the block). This work should only be carried out by qualified specialist personnel familiar with assembling gearbox components and adhering to torque specifications.

1. Preparation: The engine must be dismantled, and all attached parts removed. Oil and coolant must be drained.

2. Disassembly: The engine block must be split to gain access to the gearbox assembly.

3. Replacement: Remove the old shaft and install the new transmission shaft, replacing all associated bearings, oil seals, and circlips.

4. Completion: Reassemble the engine block using new gaskets and tighten all screws with the correct torque.
