Description

These workhorses have earned their reputation over decades of hard farm work, but even the best engines eventually need refreshing. This basic overhaul kit gives you the core components to bring that 6-cylinder diesel back to life without breaking the bank.

- Complete cylinder sleeve and seal package for a tight, proper bore
- High-quality 3-ring pistons with keystone top compression rings for better sealing

Built for Real Farm Work
This kit fits the legendary John Deere 4010 and 4020 series tractors with the 381 cubic inch diesel engine. Whether you're running a 4010 for hay work, using a 4020 for row crop farming, or depending on either one for heavy pulling, this engine has been the backbone of countless farm operations since the 1960s.
Made to Last
Tru-Power components are built to handle the demanding life of a farm tractor. The keystone compression rings provide better cylinder sealing under high loads, while the complete gasket set ensures your rebuilt engine stays leak-free through years of hard use.
Good to Know
This is a basic kit - bearings are sold separately, so you can choose standard or undersized based on your crankshaft condition. The kit includes both standard and overbore pistons, giving your machine shop flexibility during the rebuild. Don't forget to check connecting rod length and order the appropriate rod bolts for your specific engine configuration.
