Sleeve and Piston Kit for International Harvester 123 CID 4-Cylinder Gas Engines

Description

If you’ve got an older International Harvester tractor that’s started burning oil or losing compression, this complete sleeve and piston kit can bring that 123 cubic inch engine back to life. When pistons get worn and cylinders get scored, you don’t have to hunt around for individual parts—this kit has everything you need to do the job right the first time.

What You’re Getting

• Complete cylinder sleeve set (4 sleeves) to restore your cylinders to factory specs
• Stepped-head pistons designed specifically for these IH engines
• Matching rings, pins, and retainers for proper sealing and durability
• Overbores to 3-5/8 inches to handle cylinders that need a little extra cleanup

Built for Real Farm Work

This kit fits the 4-cylinder gas engines found in classic International Harvester tractors. These were the workhorses that handled everything from cultivating corn to running hay equipment, and they’re known for their reliability when properly maintained. The stepped-head piston design is what these engines came with from the factory, so you’re getting the correct style for optimal performance.

Made to Last

TISCO builds these engine components to handle the demands of farm work. The sleeves are properly hardened to resist wear, and the pistons are cast to the right specifications for long life. When you’re putting this much work into an engine rebuild, you want parts that’ll give you years of reliable service.

Good to Know

This is a complete rebuild job that requires proper machining and assembly. The overbore capability means your machine shop can clean up cylinders that have some wear or scoring. Make sure to have your block checked for cracks and deck height before starting, and consider replacing your rod and main bearings while you’re this deep into the engine.
