Description
When you’re working on your Ford 8N’s PTO assembly and need to replace those retainers, this little inner gasket might not look like much, but it plays a big role in keeping everything sealed up tight. This gasket sits inside the retainer assembly, creating that critical barrier between the moving parts and the outside world – without it, you’ll have gear oil making a mess and wearing out your seals faster than you’d like.
What You’re Getting
- Precision-cut gasket that fits perfectly inside retainers 8N4248B and A8NN4248A
- Quality construction from TISCO that handles the heat and pressure of PTO operation
- Must be installed before the main seal – gets the assembly sequence right from the start
- Direct replacement that matches original Ford specifications
Built for Real Farm Work
Your Ford 8N has been working farms for decades, and that PTO system has powered everything from buzz saws to hay balers to post hole diggers. This inner gasket works with your retainer assembly to keep gear oil where it belongs and dirt where it doesn’t. It’s a small part that prevents big headaches down the road.
Made to Last
TISCO has built their reputation making quality parts for classic tractors, and this gasket is no exception. The material is designed to handle the constant flexing and temperature changes that come with PTO work, staying flexible season after season without cracking or hardening.
Installation Notes
Remember – this gasket goes in before you install the seal, not after. It’s easy to get the sequence mixed up when you’re in the middle of a repair. Take your time to clean the retainer housing thoroughly before installation, and make sure the gasket sits flat with no wrinkles or folds that could cause leaks.
