Description
When your dual-belt system starts squealing or you see one belt getting slack while the other stays tight, it’s time to replace both. Check out the deal on Belt at sutterbros.com Mixing old and new belts in a dual system is asking for trouble—the new belt does all the work while the old one just goes along for the ride, leading to quick failure and potential overheating when you’re in the thick of harvest or heavy field work.
What You’re Getting
- Matched pair ensures equal tension and prevents one belt from carrying all the load
- AVX13 heavy-duty profile designed for the demands of high-horsepower cooling systems
- 1575mm length engineered specifically for your tractor’s pulley configuration
- Quality construction that handles the vibration and heat of dual-belt applications
Built for Real Farm Work
These belts are engineered for tractors that work hard—your Massey Ferguson models from compact 3125s up through the powerful 8110s, plus Case 4240 tractors. These machines see everything from loader work and hay operations to heavy tillage and harvest duties. The dual-belt setup on these tractors handles the substantial cooling demands of bigger engines and higher alternator output needed for modern farming operations.
Made to Last
The AVX13 profile provides the strength needed for dual-belt systems where belt failure means immediate trouble. Heat-resistant compounds handle the elevated temperatures under the hood, while oil-resistant materials shrug off the inevitable hydraulic and engine oil exposure that comes with farm work. Matched construction means both belts stretch and wear at the same rate.
Good to Know
Always replace both belts together—never just one. Professional installation recommended to ensure proper belt tension and pulley alignment. Always inspect fan pulley and crankshaft pulley for wear before installing new belt. Make sure both belts have identical tension using a belt tension gauge if you have one. A quick tip: mark your belts with a permanent marker during installation so you can track which one might be wearing faster—it’ll help you spot pulley alignment issues early.
