Description
There’s nothing more frustrating than finding fresh oil puddles under your tractor after a hard day’s work. A worn rear main seal is like a slow leak in your bank account—every drop that hits the ground is expensive engine oil you’re buying again. This Viton lip-type rear main seal locks that oil in tight, keeping your crankshaft properly sealed and your engine running clean.
What You’re Getting
- Viton rubber construction that handles extreme heat and chemical exposure without breaking down
- Precision-molded lip design creates a positive seal against rotating crankshaft surfaces
- Spring-loaded sealing lip maintains consistent pressure as components wear and settle
- Corrosion-resistant metal case prevents seal distortion during installation and operation
- Direct replacement design fits original seal bore without modifications
Built for Real Farm Work
This rear main seal fits agricultural diesel engines that put in long hours under demanding conditions. Whether you’re running a utility tractor on daily chores, pushing through heavy tillage work, or powering through harvest season, this seal handles the constant vibration and heat cycles that come with serious farm equipment.
Made to Last
Viton isn’t your standard rubber—it’s engineered to resist the extreme temperatures and chemical exposure that agricultural engines face. This material stays flexible in winter cold and won’t harden or crack from engine heat and diesel fuel exposure. The precision lip design maintains its sealing ability even as your engine accumulates thousands of hours.
Good to Know
Installing a rear main seal typically means pulling the transmission or engine oil pan, depending on your engine design. While you’re in there, it’s smart to inspect the crankshaft surface for wear or scoring that could cause premature seal failure. Clean installation and proper alignment are critical—this isn’t a place to rush the job if you want lasting results.
