Description
If you’ve noticed transmission fluid weeping around the input shaft area, that little O-ring might not seem like much, but it’s what keeps your transmission properly sealed and protected. When transmission fluid starts leaking, it creates a mess that attracts dirt and debris, and a small seal replacement now can save you from much bigger transmission problems down the road. This handy O-ring keeps your transmission fluid where it belongs—inside protecting your gears and bearings.
What You’re Getting
- Precision-manufactured O-ring designed specifically for input shaft sealing applications
- Quality seal material that maintains flexibility across farm temperature ranges
- Engineered to handle the constant rotation and pressure changes that input shafts experience during normal operation, while resisting chemicals found in modern transmission fluids
- Direct replacement that restores proper sealing without modifications
Built for Real Farm Work
These Ford New Holland and Case IH tractors handle diverse farm tasks from field preparation and planting to hay operations and loader work around the farmyard. Whether you’re pulling a cultivator through tough soil, running a hay baler through long summer days, or doing daily chores with a front-end loader, your transmission works hard and needs proper sealing.
Made to Last
A proper seal prevents dirt and moisture from entering your transmission, which could cause premature wear and expensive internal damage. Oil leaks not only waste expensive fluid but also create slip hazards and can lead to costly transmission damage if left unchecked. This O-ring is built to handle the demanding conditions your tractor faces every day.
Installation Notes
O-ring replacement typically requires accessing the input shaft area, so it’s smart to tackle this during other transmission service work. Clean the sealing surfaces thoroughly before installation, and always use fresh transmission fluid when reassembling. A good tip from seasoned mechanics: inspect the shaft surface for any scoring while you’re in there—even minor grooves can cause new seals to leak.
