Description

When you’re doing a head gasket job, there’s nothing worse than finding out halfway through that you need to hunt down bolts. This head bolt kit gives you everything you need for a proper engine rebuild, with Grade 8 hardware that’s built to handle the pressures and temperatures of diesel engine operation. These high-strength bolts are engineered to hold tight under the extreme conditions your tractor engine faces every day.

What You’re Getting

Grade 8 bolt construction for maximum tensile strength and reliability
Precise torque specification of 130 lb-foot for proper clamping force
Complete kit eliminates multiple parts runs and ensures compatibility
Heat-treated fasteners designed for diesel engine applications
OEM-quality components that meet John Deere specifications

Built for Real Farm Work

These bolts are made for the demanding world of agricultural diesel engines that see constant temperature cycling, high compression ratios, and the vibration that comes with heavy field work. Whether your John Deere is pulling a heavy cultivator, running a PTO-driven implement, or pushing through tough ground conditions, these Grade 8 bolts provide the clamping force needed to keep everything sealed tight.

Made to Last

Grade 8 hardware means these bolts are heat-treated for maximum strength – about twice as strong as standard bolts you’d find at a hardware store. The precise metallurgy handles the stress cycles of diesel combustion while maintaining proper torque values season after season. These aren’t the kind of bolts that stretch or fail when you need them most.

Installation Notes

Always follow the proper torque sequence when tightening – usually from the center outward in a star pattern. Clean the block threads thoroughly before installation since any debris will give you false torque readings. The 130 lb-foot specification should be reached gradually, typically in three stages, using a quality torque wrench for accuracy.
