Description
When your old IH tractor starts burning oil or you’re losing compression on that trusty C248 gas engine, it’s usually time for a sleeve and piston refresh. Those classic M, MV, W6, and O6 tractors have been working hard for decades, and eventually the cylinder walls wear out and the pistons get tired. This complete kit gives you everything needed to bring that 248-cubic-inch four-cylinder back to like-new compression and performance.
What You’re Getting
- Complete cylinder sleeves that restore proper bore dimensions and surface finish
- Matched pistons designed specifically for the overbore from 3-7/8 inches
- Quality piston rings that seal properly and control oil consumption
- Wrist pins and retainers to complete the assembly
- Everything pre-matched so components work together perfectly
Built for Real Farm Work
These classic International Harvester tractors were the workhorses of mid-century agriculture. The M series handled cultivating and lighter field work, while the W6 tackled heavier pulling duties. The O6 and OS6 models brought orchard and vineyard capabilities to the lineup. All shared the reliable C248 gas engine that’s known for running smooth and lasting when properly maintained.
Made to Last
TISCO builds these sleeve and piston sets to handle the demands of agricultural work. The sleeves provide a fresh, properly-sized bore surface, while the stepped-head pistons are designed to work with the combustion chamber shape of these engines. Quality materials and precise machining ensure good ring seal and long service life.
Good to Know
This is an overbore kit, so you’ll need to have your block bored out to accommodate the larger sleeves. Most machine shops familiar with vintage tractors can handle this work. Take your time during assembly and follow proper torque specifications – these old engines respond well to careful workmanship and will reward you with years of reliable service.
