Description
When your PTO won’t engage or your implement keeps shutting down unexpectedly, it’s often because the input shaft that connects your tractor’s PTO system to the transmission has worn out or failed. This critical component takes the engine power from your transmission and delivers it to the PTO clutch system—and when it’s not working right, you’re stuck with implements that won’t run when you need them most.
What You’re Getting
- Direct replacement for Case IH Quantum and JX series tractors from serial number 5177146 and up
- Precision-machined shaft that delivers smooth power transfer from your transmission to the PTO system
- Heavy-duty construction built to handle the constant torque loads and vibration of PTO operation
- Engineered to original equipment specifications for reliable fit and performance
Built for Real Farm Work
This input shaft fits Case IH Quantum series tractors (65V through 105V) and JX series models (JX1060V through JX1095N) that power everything from rotary cutters and hay balers to post-hole diggers and manure spreaders. These mid-range tractors are workhorses on farms and ranches where reliable PTO operation is essential for getting hay made, fields maintained, and livestock fed.
Made to Last
The PTO input shaft takes a beating every time you engage your implements, transferring tremendous rotational forces while dealing with the shock loads that come from hitting rocks or changing ground conditions. This replacement is built from quality materials with proper heat treatment to handle the stress and keep your PTO system running smoothly for years to come.
Installation Notes
This is a transmission-internal component that requires splitting the tractor between the engine and transmission for installation. The job calls for specialized tools and experience with tractor drivetrain work, so it’s typically best handled by a qualified shop. Make sure to check your tractor’s serial number—this part is specifically for units from serial 5177146 forward.
