Description
When your 4010 or 4020 starts blowing blue smoke, burning oil, or just doesn’t have the power it used to have, it’s time for a complete engine rebuild. These workhorse tractors put in decades of faithful service, but eventually that 6-cylinder diesel needs more than just an oil change. This major overhaul kit gives you everything you need to bring that engine back to like-new performance so you can keep farming with the tractor you know and trust.
What You’re Getting
- Complete cylinder sleeves and seals for a tight, proper fit that stops oil consumption
- Pistons with 3-ring design and Keystone top compression ring for maximum sealing power
- Standard and oversize bore options so you can machine to the best fit for your block
- Rod bearings, main bearings, and connecting rod bolts for a solid rotating assembly
- Full gasket set and crankshaft seals to keep everything sealed up tight
Built for Real Farm Work
This kit is specifically designed for the 6-cylinder, 381 cubic inch diesel engines that powered the legendary 4010 and 4020 series tractors. These were the backbone machines of American agriculture in the 1960s and 70s, pulling everything from plows to balers. Whether you’re running a restored 4010 for hay work or still depending on that trusty 4020 for field cultivation, this overhaul kit brings the engine back to factory specifications.
Made to Last
This TISCO replacement is built with quality materials and proper heat treatment to handle constant rotation, varying loads, and the vibration that comes with heavy implement work. The sleeve and seal combinations are engineered to maintain proper compression and oil control for years of hard use. Everything meets or exceeds original equipment specifications.
Installation Notes
This is a major engine rebuild job that requires machine shop work and experienced mechanical skills. You’ll need to bore the cylinders to fit the sleeves and check all clearances carefully. Take your time with the assembly and follow proper torque specifications – a good rebuild done right will give you another 20 years of reliable service.
