Description
When you’re connecting high-horsepower implements to your PTO, you need a flange that can handle the torque without backing down. This 2-1/2 inch bore flange is built for the demanding 1480 and 1550 series drivelines that power your biggest hay tools, balers, and heavy-duty equipment. If you’ve been dealing with worn splines or a loose connection that’s causing vibration, this is the solid foundation your driveline needs.
What You’re Getting
- Precision-machined 2-1/2 inch bore fits large PTO shafts perfectly
- Standard 5/8 x 5/16 inch keyway ensures proper torque transfer
- Heavy-duty construction designed for 1480/1550 series applications
- Direct replacement that restores proper driveline alignment
Built for Real Farm Work
This flange is designed for the heavy-duty PTO applications where 1480 and 1550 series drivelines shine. We’re talking about big square balers, large disc mowers, heavy-duty rotary cutters, and other implements that demand serious power transfer. These are the machines that make hay in a hurry and handle the toughest cutting conditions.
Made to Last
When you’re pushing 150+ horsepower through a driveline, everything needs to be built right. This flange is machined to precise tolerances and heat-treated for durability. The keyway is cut clean and true, so your key seats properly and stays put under load.
Installation Notes
Make sure your shaft is clean and check the keyway for wear before installation. A light coat of anti-seize on the bore helps with future removal. Always verify proper driveline length and U-joint phasing after installing any new flange components.
