Description

If you’ve got one of those classic International Harvester workhorses from the Cub to the Super A, you know these machines were built to handle dusty conditions that would choke modern tractors. This air cleaner cap is the final piece that seals your oil bath air cleaner system, keeping dust and debris from sneaking in around the top while your tractor breathes clean air through the proper channels.

What You’re Getting

Direct replacement cap that fits the outside pipe perfectly with 1-3/8″ ID opening
4-1/8″ body diameter matches your original equipment specifications
Durable construction that handles decades of farm work and weather exposure
Proper seal to maintain the effectiveness of your oil bath air cleaner system
TISCO quality that’s built to outlast the competition

Built for Real Farm Work

These legendary tractors – from the little Cub that’s perfect for garden work and small chores, to the bigger A and B series machines that handled serious farming tasks – all relied on oil bath air cleaners to survive in dusty conditions. Whether your Cub is mowing around the farmstead, your A is cultivating vegetables, or your B is pulling implements through dry fields, this cap ensures your air cleaner does its job properly.

Made to Last

Oil bath air cleaners were the gold standard for dusty conditions, and every component had to be built right. This cap maintains the seal that keeps your system working as designed, preventing dust from bypassing the oil bath filtration that protects your engine from premature wear.

Installation Notes

This cap simply fits over the outside pipe of your air cleaner assembly – no modifications needed. Make sure the sealing surface is clean before installation, and check that it sits flush to maintain proper filtration. If your old cap was stuck from years of use, a little penetrating oil helps with removal.
