Description
When your hydraulic system starts whining or loses pressure, it’s often because the drive shaft between your engine and hydraulic pump has worn out. This isn’t just any shaft—it’s the critical connection that transfers power from your engine to run all your hydraulics. Without it working properly, your loader, three-point, and power steering all suffer.
What You’re Getting
- Complete 15-1/2 inch drive shaft assembly with coupler already attached—no separate parts to track down
- 7/8 inch left-hand thread adapter end that threads securely into your engine’s accessory drive
- 13-spline coupler end engineered for positive engagement with your hydraulic pump
- Heavy-duty construction built to handle the constant rotation and torque loads of industrial work
- Direct replacement design that installs just like the original factory part
Built for Real Industrial Work
This shaft is specifically designed for Massey Ferguson 40B and 50A industrial tractors—machines that spend their days moving materials, operating loaders, and powering hydraulic attachments around job sites and farms. These aren’t light-duty applications, and this shaft is built to match the demands of continuous operation under load.
Made to Last
Industrial hydraulic systems run harder and longer than most farm applications. This drive shaft features precision-machined splines that maintain proper engagement even after thousands of hours of operation. The steel construction handles vibration and shock loads without the flex or wear you’d see in lighter components.
Installation Notes
Pay attention to that left-hand thread on the adapter end—it tightens counter-clockwise, which is opposite from most threads. Clean both the engine mounting point and pump splines thoroughly before installation. A thin coat of anti-seize on the threads prevents future removal headaches, and proper spline alignment ensures smooth operation from day one.
