Description
When you start noticing gear oil spots under your old International H or Super H, chances are the countershaft seal has called it quits. A worn seal doesn’t just make a mess in the shop—it lets expensive gear oil leak out while allowing dirt and moisture to work their way into your transmission. That’s trouble you don’t need when there’s work to be done.
What You’re Getting
- TISCO quality construction that’s been building reliable tractor parts for decades
- Direct replacement for OEM part 43308D—no modifications needed
- Durable rubber compound designed to handle gear oil and temperature swings
- Precise fit that seals tight while allowing smooth countershaft operation
Built for Real Farm Work
This seal fits the International Harvester H and Super H series tractors that are still earning their keep on farms across the country. Whether your old H is running a brush hog, pulling a disc, or handling general farm duties around the place, this seal keeps your transmission properly lubricated and protected.
Made to Last
Farm equipment seals take a beating from constant rotation, temperature changes, and the vibration that comes with real work. This replacement seal uses quality materials that resist gear oil breakdown and maintain flexibility even after years of service.
Good to Know
Before installation, clean the seal bore thoroughly and inspect it for scratches or damage that could cause the new seal to leak. Apply a thin coat of transmission fluid to the seal lip before installation to prevent damage during assembly. While you’ve got things apart, it’s a good time to check your gear oil level and condition.
