Crankshaft Pulley for International Harvester A, B, and C Series Tractors

Description

If your International Harvester A, B, or C tractor’s fan belt keeps slipping or you’re noticing vibration from the front of the engine, a worn crankshaft pulley might be the culprit. This essential component drives your cooling fan, generator, and other belt-driven accessories that keep your engine running cool and your electrical system charged. When it’s wobbling or worn, everything downstream suffers—and that’s trouble you don’t need during busy seasons.

What You’re Getting

• Precision-machined pulley that runs true and keeps belts tracking properly
• Durable construction designed to handle the constant rotation and belt tension
• Direct replacement that bolts right onto your crankshaft without modifications
• Proper groove dimensions to maintain correct belt alignment and prevent slippage

Built for Real Farm Work

This pulley is made specifically for the International Harvester A, B, and C series tractors—those reliable workhorses that have been cultivating, plowing, and powering farm operations for decades. Whether you’re running your A on row crop work, using your B for general farm duties, or putting your C through heavy cultivation tasks, this pulley ensures your engine accessories keep running smoothly.

Made to Last

Farm tractors don’t get to take breaks, and neither do their parts. This TISCO pulley is built from quality materials to withstand the vibration, heat cycles, and constant use that come with farm work. The balanced design reduces engine stress and helps prevent premature bearing wear.

Good to Know

Installation requires removing the fan and belts to access the crankshaft bolt. A puller might be needed to remove the old pulley if it’s been on there for years. Make sure to torque the crankshaft bolt to spec when installing—too loose and it’ll work free, too tight and you risk crankshaft damage.
