Built for Real Farm Work
This bolt fits a wide range of New Holland tractors from T5 utility models through heavy-duty T7 series machines. Whether you’re running implements, working with a loader, or pulling heavy equipment, these mid to high-horsepower tractors excel in row crop farming, hay production, livestock operations, and heavy field work. Case Puma series tractors also use this same bolt specification for their belt tensioner systems.
Made to Last
Agricultural equipment puts fasteners through constant vibration, temperature swings, and exposure to chemicals and moisture. This bolt is built from quality steel that maintains its strength and threading integrity through countless field hours and maintenance cycles.
Installation Notes
This is a straightforward replacement—just remove the old bolt and thread in the new one to the proper torque specification. Installation requires releasing belt tension using appropriate tools and inspecting the entire serpentine belt system while you’ve got things apart. It’s also a good time to check belt condition and pulley alignment.
