Description

There’s nothing worse than watching engine oil slowly drip onto the barn floor from your International Harvester’s timing cover. A leaking front crankshaft seal doesn’t just mean lost oil—it’s an invitation for dirt and debris to work their way into places they don’t belong. When you spot that telltale seepage around the crankshaft pulley, it’s time to swap out that worn seal before it turns into a bigger problem.

What You’re Getting

Direct replacement that fits exactly like the original factory seal
Quality construction built to handle the constant rotation and pressure changes of farm work
Durable materials that resist heat, oil, and the vibration that comes with heavy tractor use
Proper seal design that keeps oil in and contaminants out where they belong

Built for Real Farm Work

This TISCO seal is designed for International Harvester tractors that have been putting in honest work for decades. Whether you’re running an older utility tractor for livestock chores or maintaining vintage equipment that still earns its keep, this seal handles the same demanding conditions as the original.

Made to Last

Farm equipment doesn’t get babied, and this seal is built to take whatever your tractor dishes out. The materials are specifically chosen to handle the heat cycles from cold morning starts to hours of field work, plus the constant flexing that comes with engine vibration and varying RPMs.

Installation Notes

Plan on pulling the timing cover to get at the old seal, so set aside a good chunk of time for this job. Clean the seal bore thoroughly before installation, and take a close look at the crankshaft surface—any nicks or grooves can cause a new seal to leak from day one. A thin coat of clean engine oil on the seal lip helps it seat properly and extends its life.
