Description
If you’ve been chasing belt squealing, charging problems, or hydraulic issues on your tractor, there’s a good chance your belt tensioner isn’t doing its job anymore. Proper belt tension is critical for maintaining reliable operation of engine-driven accessories that power essential tractor functions. This tensioner pulley prevents belt slippage that can cause alternator charging issues, air conditioning failure, or hydraulic system problems during peak operating demands. When that spring-loaded tensioner gets weak or the pulley bearing goes bad, everything starts acting up. This kit gets your belt system back to working like new.
What You’re Getting
- Automatic tensioning feature eliminates manual adjustment requirements while extending belt life by preventing over-tensioning or under-tensioning conditions that cause premature wear and system failures
- Complete kit with all necessary components for a proper repair job
- Direct replacement parts that fit your 7840, TS110, or TS115 without modifications
- Professional-grade components built to handle the demands of agricultural work
Built for Real Farm Work
Ford New Holland 40 Series tractors including models 5640, 6640, 7740, 7840, 8240, and 8340, along with TS Series models TS80, TS90, TS100, TS110, and TS115 are versatile agricultural workhorses used in diverse farming operations. These mid to high-horsepower tractors excel in row crop farming, hay production, livestock operations, and heavy field work including deep tillage, large implement operation, and commercial farming applications. This kit is specifically designed for tractors without air conditioning, so the belt routing is simpler than the A/C equipped models.
Made to Last
Farm equipment takes a beating from vibration, dust, temperature swings, and constant operation. This tensioner kit uses quality bearings and springs that maintain proper tension through thousands of hours of field work. The pulley surface stays smooth and true, preventing belt wear and maintaining consistent accessory operation.
Installation Notes
Installation requires releasing belt tension using appropriate tools and following manufacturer specifications for belt routing. Replace the serpentine belt simultaneously with the tensioner for optimal system performance and reliability. Take a photo of your belt routing before you start—it’ll save you time getting everything back together. Always inspect the entire serpentine belt system including the belt, idler pulleys, and driven components during tensioner replacement. Ensure proper alignment of all pulleys to prevent premature wear and noise issues.
