Description
When your International Harvester's 264-cubic-inch gas engine starts burning oil or loses power on the hills, it's probably time to go deeper than just new rings. If you're already pulling the engine apart anyway, this basic overhaul kit gives you the essentials to bring that four-cylinder workhorse back to life. It's got everything you need for a solid rebuild—except the bearings, which you'll want to have checked and fitted separately.
What You're Getting
- New sleeves and sleeve seals for proper cylinder bore restoration and oil control
- Matched pistons with rings designed for the 4-inch bore with overbore option included
- Stepped-head pistons with 1-inch head diameter for proper compression in your gas engine
- Pin bushings and retainers plus complete gasket set for a leak-free rebuild
- Crankshaft seals to keep oil where it belongs instead of on your barn floor
Built for Real Farm Work
This kit is designed for the International Harvester 400 and W400 series utility tractors, plus the 450 and W450 models that have been the backbone of smaller operations for decades. These reliable machines handle everything from bush hogging to hay work, and when they're running right, they'll pull their weight all day long without complaint.
Made to Last
This Tru Power kit uses quality components built to handle the heat cycles and stress of farm engine operation. The stepped-head pistons are designed specifically for the combustion chamber shape of your gas engine, while the sleeve seals use modern materials that maintain their flexibility through temperature changes.
Good to Know
This is a basic kit, so you'll need to source main and rod bearings separately—most folks have their machine shop check clearances and fit the bearings anyway. The 4-inch standard bore pistons come with 4-1/8-inch overbore pistons included, giving you options depending on what your cylinders look like. Plan on having the crankshaft checked while everything's apart, and don't forget to check your oil pump and timing chain while you're in there.
