Installation Method for Head Stud Kit
Part Number - 250-4201A Application - Ford 7.3l Power Stroke Diesel
1. Clean and inspect all hardware prior to installation. Look for obvious defects or shipping damages, plus proper fit, length and dimension.
2. To ensure proper thread engagement and accurate torque readings, clean ALL threads in the block. Use a thread chaser or thread cleaning tap for M12 X 1.75
3. If the cylinder head studs protrude into a water jacket, lubricate the block threads of the studs with a thread sealant. This will protect against rust, leaks and loosening from vibration.
4. Screw studs into the block “Hand tight ONLY!!”. Note: the 6.625 in. ( short) studs in this kit install along the intake manifold side of the cylinder head under the fuel injectors in the No. 4, 5, 12, and 13th position of the factory torque sequence. Note: Loctite may be used IF a PERMANENT MOUNTING of the studs is preferred. The FASTENERS, however, must be torqued PROIR to the Loctite setting up
5. Install the cylinder head(s) and check for binding or misalignment.
6. Lubricate the stud threads, nuts and washers with high-quality lubricant such as ARP Ultra-Torque Fastener Assembly Lubricant. Do NOT use motor oil as a lubricant!! This is due to higher friction on the studs as well as inconsistencies in the clamping force of the fasteners when motor oil or low quality lubricants are used.
