Hard starting, rough idle, or blue smoke on startup are sure signs those valves, springs, and related parts have seen better days after thousands of hours of hard work. This complete valve overhaul kit gives you everything needed to restore proper compression and get your engine running like it should again.
What You’re Getting
- Complete set of intake and exhaust valves engineered for the demands of turbocharged operation
- Valve springs designed to handle higher compression and operating pressures of diesel engines
- Valve caps and keys that keep everything properly seated under heavy loads
- All components sized specifically for the 404 CID 6-cylinder turbocharged diesel engine

Built for Heavy-Duty Work
This kit is designed for the 404 CID turbocharged diesel engines found in larger tractors and heavy equipment from serial numbers 245547 to 335845. These are the workhorses that power through demanding applications like heavy tillage, large implements, and continuous operation where reliability matters most. The turbocharger adds power but also increases the stress on valve components, making proper valve train maintenance critical.
Made to Last
Diesel engines work hard and these valve components are built to match that durability. The valves are manufactured from quality materials that resist heat and corrosion, while the springs maintain proper tension through countless cycles of operation. Each component is precision-made to handle the higher pressures and temperatures that come with turbocharged diesel operation.
Good to Know
This is a complete valve overhaul kit, but you’ll want to have the head checked for warpage and the valve seats inspected during installation. It’s also a good time to check valve guides for wear. Having the machine work done by a qualified shop ensures everything seals properly and performs as designed.
