Complete Engine Overhaul Kit for International Harvester M/MV/W6/OS6 Series Tractors

Description

When your old International starts burning oil or losing compression, you know it’s time for a complete rebuild. This isn’t a weekend project, but when you’re done, you’ll have an engine that runs like it rolled off the assembly line back in the day. This complete kit contains everything you need for a proper overhaul: sleeves & sleeve seals, pistons & rings, pins & retainers, pin bushings, complete gasket set, crankshaft seals, intake & exhaust valves, springs, guides, valve keys.

What You’re Getting

• Complete rebuild kit with all the major wear components—no hunting around for missing pieces
• High compression stepped-head pistons that’ll give you better power and fuel economy than the old flat-tops
• Standard rod and main bearings included, so you won’t get stuck waiting on back-ordered parts
• 4-inch overbore pistons supplied alongside the standard 3-7/8 inch bore for flexibility on cylinder condition
• Early crank design compatibility ensures proper fitment on your vintage International

Built for Real Farm Work

This kit is designed specifically for the International Harvester M Series, MV Series, OS6 Series, and W6 Series tractors—the workhorses that built American agriculture. These 248 cubic inch, 4-cylinder gas engines were known for their reliability, and with this rebuild, yours will be ready for another generation of field work, whether you’re cultivating, plowing, or running a PTO-driven implement.

Made to Last

Tru-Power builds these kits to original factory specifications, using materials that can handle the demands of farm work. The stepped-head pistons are designed for higher compression ratios, giving you more power per gallon of gas—something your wallet will appreciate during busy seasons.

Good to Know

This is a complete teardown job that requires engine removal and machine shop work for boring cylinders and checking clearances. Make sure you have your cylinders measured before ordering—the kit includes both standard and 4-inch overbore pistons, but you’ll want to know which ones you need. A good shop manual and the right tools will save you headaches during assembly.
