Description
When you notice hydraulic fluid dripping from your tractor’s final drive or rear axle area, it’s usually this small but critical seal that’s given up. A failed final drive oil seal doesn’t just make a mess—it lets precious hydraulic fluid leak out while allowing dirt and moisture to work their way in, which can turn into expensive damage down the road. This 40mm x 55mm x 7mm seal keeps your final drive properly sealed so you can focus on the work instead of chasing leaks.
What You’re Getting
- Precision-molded rubber construction that handles hydraulic pressure and temperature swings
- Spring-loaded lip design maintains constant sealing pressure even as components wear slightly
- OEM-quality materials that resist breakdown from hydraulic fluid and UV exposure
- Exact 40mm x 55mm x 7mm dimensions for perfect fit in your final drive housing
Built for Real Farm Work
This seal fits the final drive assemblies on Massey Ferguson 300 series tractors like the 340, 350, 355, 360, 362, 365, 390, and 396, plus the 3000 series models including the 3050, 3060, and 3065. These are dependable mid-range tractors that handle everything from hay operations and loader work to cultivation and general farm chores where reliable hydraulic systems are essential.
Made to Last
Final drive seals take a beating from constant pressure, temperature changes, and contamination, so this one’s built tough. The rubber compound stays flexible through hot summers and cold winters while the metal case maintains proper fit in the housing. Quality construction means it’ll hold up to the vibration and stress that comes with field work.
Installation Notes
Replacing this seal requires removing the axle hub and accessing the final drive housing—it’s not a quick roadside fix. Clean the seal bore thoroughly and check for any rough spots that could damage the new seal. A thin coat of clean hydraulic fluid on the seal lip helps with installation and initial sealing.
