Description
When your tractor’s charging system isn’t keeping up, you know it’s time to check that generator belt. A worn belt can leave you dealing with a dead battery right when you need your tractor most. This TISCO replacement belt gets your International Harvester back to charging properly so you can keep working without worrying about electrical problems.
What You’re Getting
- Exact 21-inch length matches factory specifications perfectly
- Proper 0.515-inch width ensures correct fit and grip on pulleys
- Heat and oil-resistant construction that stands up to engine bay conditions
- Quality materials that won’t stretch or slip under normal operating loads
Built for Real Farm Work
This belt is designed to handle the constant speed changes and varying loads that come with running implements, using hydraulics, and working in the field. Whether you’re plowing, cultivating, or running a PTO, this belt keeps your generator spinning at the right speed to maintain proper charging voltage.
Made to Last
TISCO builds their belts to handle the heat, oil, and vibration that’s part of daily tractor operation. The reinforced construction resists cracking and stretching, while the grippy surface maintains proper traction on both the crankshaft and generator pulleys season after season.
Installation Notes
This is a direct replacement that installs just like the original. Make sure to check your generator and crankshaft pulleys for wear or damage while you’re changing the belt—a rough pulley will chew up a new belt in no time. Proper belt tension is key for good charging and long belt life.
