Complete Engine Overhaul Kit for International Harvester A, AV, B, BN & Super A Series Tractors

Description

When it’s time for a complete rebuild on your classic IH tractor, you don’t want to hunt down parts from six different suppliers or worry about pieces that don’t quite fit together. This comprehensive overhaul kit brings together everything you need to bring that 113 cubic inch engine back to life—sleeves, pistons, rings, gaskets, valves, and all the hardware to get it running like it did when it rolled off the line.

What You’re Getting

• Complete sleeve set with seals to restore proper bore dimensions and compression
• Stepped-head pistons with rings designed for the unique compression ratio of these engines
• Full valve train components—intake and exhaust valves, springs, guides, and keepers
• Complete gasket set with crankshaft seals to keep fluids where they belong
• Pin bushings and retainers that handle the load these tractors were built for

Built for Classic Farm Work

This kit restores the heart of some of the most beloved utility tractors ever made. Whether you’re rebuilding an A series that’s been handling chores around the farmstead, a B series that’s been your go-to cultivating tractor, or a Super A that’s earned its keep in tight quarters, this engine was the reliable workhorse that kept smaller farms productive during the golden age of agriculture.

Made to Last

These aren’t cut-rate replacement parts—this is a quality rebuild kit that understands what these old engines need. The sleeves are properly sized for the original bore specifications, and the stepped-head pistons match the compression design that made these engines so dependable. Every gasket and seal is made to handle the heat cycles and vibration that come with real farm work.

Good to Know

This is a complete overhaul kit minus the main and rod bearings, which should be measured and ordered separately based on your crankshaft condition. Take time to check your cylinder bore condition before assembly—these engines were built when metal was thick and quality mattered, so most blocks clean up nicely with proper machine work.
