Description

Nobody likes finding a puddle of expensive hydraulic fluid under their tractor, especially when it means something’s not sealing right inside the transmission. If you’ve noticed oil spots where you park or caught a whiff of hot transmission fluid, there’s a good chance your input shaft seal has called it quits. This replacement seal keeps that costly fluid where it belongs and protects your transmission from contamination that can cause serious damage down the road.

What You’re Getting

Pack of 2 seals (sold individually) so you can tackle multiple machines or keep a spare on hand
Precision-molded design that restores proper sealing without any modifications
High-quality materials that handle the heat, pressure, and fluid exposure in modern transmissions
Direct OEM replacement that fits exactly like the original factory seal

Built for Real Farm Work

These seals fit the Massey Ferguson 4200 and 4300 series tractors that handle everything from cultivation and planting to hay production and loader work. Whether you’re running a 4235 on a disc-mower or pushing your 4360 through heavy tillage, these mid-horsepower machines work hard all season long. The input shaft seal is what keeps transmission fluid from leaking out around the rotating shaft that transfers power from your clutch to the transmission.

Made to Last

Transmission seals face tough conditions – constant rotation, temperature swings from cold mornings to full-operating heat, and the chemical exposure from modern hydraulic fluids. This seal uses compounds specifically designed to resist breakdown from these demanding conditions while maintaining the flexibility needed for a tight seal even as components wear slightly over time.

Installation Notes

Input shaft seal replacement typically requires splitting the tractor to access the transmission input area, so this isn’t a quick roadside fix. While you’re in there, it’s smart to inspect other seals and replace anything that looks questionable. Clean all sealing surfaces thoroughly and check the input shaft for wear grooves that could cause the new seal to leak.
