Description
Nothing ruins a good day in the field faster than a cylinder head that won’t seal properly. When you’re rebuilding a John Deere 4-cylinder diesel engine, those head bolts need to be fresh and properly torqued to keep everything sealed tight. This complete screw kit gives you all the hardware you need for a professional head job without making multiple trips to town hunting for the right bolts.
What You’re Getting
- Complete 18-piece kit with all the bolts needed for proper cylinder head installation
- Includes 16 main head bolts plus 2 additional fasteners for full coverage
- Proper grade hardware designed to handle the torque specifications and thermal cycling of diesel engines
- OEM quality construction ensures reliable sealing and prevents future problems
Built for Hard-Working Engines
This kit fits the 4-cylinder diesel engines found in a wide range of John Deere tractors from utility models up through mid-size row-crop machines. These engines see everything from daily loader work and field prep to planting, cultivation, and harvest operations. The cylinder head bolts are critical for maintaining proper combustion chamber sealing and preventing coolant leaks that can turn into expensive problems.
Made to Last
Engine rebuilding isn’t something you want to do twice. These bolts are manufactured to the same specifications as the originals, with the proper metallurgy to handle repeated heat cycles and the stretch characteristics needed for correct clamping force. They’ll maintain their torque over thousands of hours of operation.
Installation Notes
Always replace head bolts during engine rebuilds – reusing old bolts is asking for trouble. Follow the proper torque sequence and specifications in your service manual, and consider using a quality thread locker on the threads. A torque wrench is essential for this job – don’t guess at bolt tension when sealing combustion chambers.
