Description
Oil dripping under your Ferguson or MF 35 isn’t just messy—it’s telling you the rear crankshaft seal is done for. When that seal goes bad, engine oil leaks into the clutch housing and you’ll start having clutch problems on top of the mess. This replacement seal stops the leak and keeps your engine oil where it belongs.
What You’re Getting
- Exact fit seal with 104mm ID, 130mm OD, and 14mm width to match your engine specs
- Quality construction that handles the constant rotation and heat of the crankshaft
- Proper sealing lip design that maintains contact without excessive drag
- Direct replacement that installs in the original seal housing
Built for Real Farm Work
This seal fits the legendary Ferguson TEF20 and early Massey Ferguson 35 and FE35 tractors—the same machines that revolutionized farming with Ferguson’s three-point hitch system. Whether your Little Grey Fergie is still earning its keep on a small farm or you’ve got an MF 35 handling loader work, this is the seal that keeps engine oil from contaminating your clutch.
Made to Last
The rear main seal takes a beating from constant crankshaft rotation, engine heat, and oil pressure. This seal uses quality materials and proper spring tension to maintain a tight seal while allowing smooth crankshaft rotation. It’s built to handle the demands of these reliable old engines that just keep running.
Installation Notes
Replacing the rear main seal requires splitting the tractor between the engine and transmission, so it’s typically done during clutch work or engine overhaul. Clean the crankshaft and seal housing thoroughly before installation, and use a proper seal driver to avoid damage. Check the crankshaft for wear or scoring that could cause premature seal failure.
