Description

If your old International Harvester tractor is starting to show signs of magneto trouble—maybe it’s getting harder to start or you’re noticing some oil seepage around the magneto housing—there’s a good chance the gaskets have given up after decades of faithful service. This complete gasket set gets your H4 magneto sealed up tight and ready for another long stretch of reliable ignition.

What You’re Getting

Complete set of gaskets specifically made for H4 magneto systems
Proper sealing materials that handle the heat and vibration inside a magneto
All the pieces you need to properly rebuild the magneto housing seals
Quality construction from TISCO, a trusted name in aftermarket tractor parts

Built for Real Farm Work

This gasket set is designed for International Harvester tractors equipped with H4 magneto ignition systems, which were workhorses on countless IH tractors from the classic Farmall days through later utility models. Whether you’re working on a vintage Farmall or another IH machine, these gaskets help maintain the precise tolerances your ignition system needs to fire consistently.

Made to Last

Magneto gaskets deal with constant temperature changes, vibration, and the occasional oil splash. This set uses materials that stay flexible in cold weather and won’t break down from heat cycling. The gaskets maintain their seal even when your tractor sits through a hard winter or works through a hot summer.

Installation Notes

When you’re tearing into the magneto, take your time to clean all the old gasket material off the mating surfaces—a razor blade and some solvent work well for this. Check the housing for any cracks or warping while you’ve got it apart. A thin coat of gasket sealer on both sides helps ensure a lasting seal.
