Description
When your John Deere 4030 starts burning oil, losing power, or smoking more than it used to, it’s time for some serious engine work. This basic in-frame kit gets you back to reliable operation without the cost and downtime of a full teardown. You’ll have everything needed to refresh those tired internals and get back to the field work that pays the bills.
What You’re Getting
- Complete cylinder sleeve and seal set restores proper compression and stops oil burning
- New pistons with 3-ring design and keystone top ring for maximum power and efficiency
- Pins and retainers engineered to handle the workload of a 4030’s 329 cubic inch engine
- Valve-grind gasket set seals everything up tight after head work
- Oil pan gasket keeps the bottom end leak-free for years to come
Built for Real Farm Work
The 4030 series tractors are workhorses known for their dependability in everything from row crop farming to hay operations. This 6-cylinder, 329 cubic inch diesel engine was designed to pull heavy implements day after day. Whether you’re running a 4030 on cultivation duties, powering a hay baler, or using it for loader work around the farm, this kit restores the power and reliability these machines were built for.
Made to Last
Tru-Power builds these kits to handle the demanding conditions farm tractors face every day. The sleeves are precision-machined for proper fit and long life, while the pistons feature that keystone top ring design that seals better and lasts longer than standard rings. Everything’s manufactured to meet or exceed original specifications.
Good to Know
This is an in-frame kit, so you can do the work without pulling the engine completely apart. You’ll need to check your connecting rod bolt length and add either TP-R74194 bolts for 2.125-inch length or TP-R80033 for 2.325-inch applications. Have your machine shop check the head for warpage and do any valve work while you’ve got things apart.
