Description

If you’ve noticed hydraulic fluid spots under your Fiat 90 series tractor or felt that sluggish shift response, chances are your input shaft seal has given up the fight. This small but critical seal keeps your transmission fluid where it belongs—inside protecting those expensive gears and bearings—while keeping dirt and water from turning your transmission into an expensive repair bill.

What You’re Getting

Precision-engineered seal designed specifically for Fiat 90 series transmission systems
Quality rubber compound that stays flexible through temperature swings and resists transmission fluid breakdown
Spring-loaded lip design maintains proper sealing pressure even as normal wear occurs
Direct replacement part that fits your original specifications without modifications

Built for Real Farm Work

This seal is designed for the full range of Fiat 90 series tractors, from the smaller 55-90 utility models up to the big 180-90 workhorses. Whether you’re running a 70-90 around the dairy with a loader or pulling heavy tillage with a 140-90 DT, this seal handles the constant motion and pressure changes that come with serious farm work.

Made to Last

Farm transmissions work hard, with constant shifting under load and temperature extremes that destroy inferior seals. This seal uses quality materials specifically chosen to handle transmission fluid exposure and the heat generated during heavy operations. The construction prevents the gradual leaks that slowly drain your fluid and lead to much bigger problems.

Installation Notes

Input shaft seal replacement typically requires partial transmission disassembly, so it’s often done during other transmission service to save on labor. Clean the seal bore thoroughly before installation and check the shaft surface for wear grooves that could cause the new seal to leak. Apply a thin coat of transmission fluid to the seal lip before assembly.
