Description

Nothing’s worse than spotting oil spots under your tractor or catching that telltale whiff of oil smoke around the engine. A leaking rear main seal can turn a small annoyance into a big problem if you let it go. This seal sits at the back of your engine where the crankshaft exits to connect to the transmission, and when it starts leaking, you’ll know it pretty quick.

What You’re Getting

Premium rubber construction that handles the heat and pressure of hard-working engines
Precision-molded design ensures a tight seal against the crankshaft surface
Direct OEM replacement—fits exactly like the original seal that came with your engine
High-temperature resistant material that won’t crack or harden over time

Built for Real Farm Work

This seal is designed for the Cummins 4B and 6B engines that power your Case IH Maxxum tractors. These are serious workhorses built for row-crop farming, hay operations, and heavy field work. Whether you’re running a 5120 on the smaller jobs or pushing a MX170 through the big fields, this seal keeps your engine oil where it belongs.

Made to Last

Engine seals take a beating from constant rotation, heat cycles, and pressure changes. This seal is built with high-grade materials that stand up to farm conditions and keep doing their job season after season. It’s the same quality you’d get from the dealer, but without the markup.

Installation Notes

Replacing a rear main seal is a transmission-off job, so it’s often done during clutch work or other major repairs. Make sure the crankshaft surface is clean and smooth before installing the new seal. A little engine oil on the seal lip helps it slide into place and prevents damage during startup.
