Description
If you’ve noticed transmission fluid spots under your Case tractor or caught a whiff of gear oil where you shouldn’t, your input shaft seal has probably given up the fight. A worn input shaft seal lets expensive transmission fluid leak out while allowing dirt and moisture to sneak in – two problems you don’t need when there’s work to do. This replacement seal gets things back to normal and keeps your transmission protected.
What You’re Getting
- Proper 30x37x4mm dimensions that fit Case transmission housings exactly
- Quality seal material that stands up to transmission fluid and temperature swings
- Spring-loaded lip design that maintains sealing pressure as it wears
- Direct replacement – no modifications or adapters needed
Built for Real Farm Work
This seal fits a wide range of Case tractors from the compact 43 series utility machines up through the bigger 56 series row-crop tractors. Whether you’re running a 744 with a loader, pulling implements with an 855, or working hay ground with a 956XL, these are the workhorses that keep farms running and they all depend on proper transmission sealing to do their job.
Made to Last
This seal handles the constant rotation and pressure changes that input shafts experience during normal operation, with quality materials that resist transmission fluid exposure and temperature extremes. The rubber stays flexible through hot summers and cold winters, maintaining that critical seal between your transmission and the outside world.
Installation Notes
Clean the seal bore thoroughly before installation – any dirt causes immediate seal failure, and inspect the shaft surface for scratches that create leak paths. Apply a thin coat of transmission fluid to the seal lip before installation to prevent damage during assembly. This is typically a job for when the transmission’s already apart for other service.
