Description
When your big John Deere starts losing compression or you see coolant in the oil, it’s time to tackle that head gasket job. This upper head gasket set gives you everything you need to seal up the top end of your 404 cubic inch turbocharged diesel without hunting down individual pieces. One kit handles the entire job, so you can get back to moving dirt instead of chasing parts.
What You’re Getting
- Complete upper gasket set designed specifically for 404 CID 6-cylinder turbo engines
- Quality TISCO gaskets built to handle the heat and pressure of turbocharged operation
- All the seals and gaskets you need for the cylinder head work in one kit
- Engineered for engines up to serial number 355845
Built for Heavy-Duty Work
This kit fits the 404 CID turbocharged diesel that powered some of John Deere’s hardest-working tractors. These were the engines pulling big implements through tough ground, running PTO equipment for hours, and handling the kind of work that puts serious stress on head gaskets. Whether you’re dealing with a high-hour machine or one that’s been worked hard, this gasket set restores the seal between your cylinder head and block.
Made to Last
TISCO builds these gaskets to handle the thermal cycling and cylinder pressures that come with turbocharged diesel operation. The materials resist the heat expansion and contraction that eventually wears out even good gaskets, and they’re designed to maintain compression even under the higher boost pressures your turbo creates.
Good to Know
Make sure to check your engine’s serial number before ordering – this kit is for engines up to s/n 355845. Head gasket work isn’t a quick job, so plan accordingly and have your torque specs handy. Clean all the old gasket material completely and check for any head or block warpage while you’re in there.
