The list above is for reference. Before purchasing, we recommend verifying the dimensions on your machine.
The pump drive shaft is the critical link between the machine's heart (engine) and its "muscles" (hydraulics). Damage to this component leads to a complete loss of hydraulic power, immobilizing the machine. Worn universal joints or splines cause vibrations that destroy seals and bearings in both the engine and the pump.
A damaged shaft risks destroying the pump and immobilizing the machine.
The cost of replacing a shaft is negligible compared to a hydraulic pump overhaul or the losses caused by downtime. Don't take the risk – order a new GX-AFTER shaft and ensure reliable power for your hydraulics.

It is very likely. Worn universal joints on the drive shaft cause an imbalance, which manifests as strong vibrations. Other causes include damaged engine or gearbox mounts, or play on the flanges.
2. Can I just replace the damaged U-joint instead of the whole shaft?Yes, in many cases this is possible, provided that the yokes in which the U-joint is seated are not worn out. If the yokes are damaged, replacing the U-joint alone will not eliminate the play, and the entire shaft must be replaced.
3. What are the differences between pump drive shafts in JCB machines?There are at least 3 variants of pump drive shafts in JCB machines, which differ in the diameter of the spline on the pump shaft. Versions are available with 25.4 mm (1 inch), 28.5 mm, and 32 mm splines. It is essential to verify which version is installed in your machine before purchasing.
