INSTALLATION METHOD FOR MAIN STUD KITS
Part Number: 155-5404 Application: Ford 390-428 cid FE Series w/ bolts for #5 cap
1. To ensure proper thread engagement and accurate torque readings, clean ALL threads in the block. Chase the
threads if necessary with ARP Thread Chaser, part number 911-0005 (1/2 -13).
2. Clean and inspect all hardware prior to installation. Look for obvious defects or shipping damages, plus proper fit,
length and dimension.
3. Screw the studs “HAND TIGHT ONLY” into the No.1-4 mains. Note 1: LOCTITE MAY BE USED IF A PERMANENT
MOUNTING OF THE STUDS IS PREFERRED. Note 2: This kit uses washers on the No.1 - 4 main caps “only”
due to clearance issues with the oil pan. It will be necessary to chamfer the holes in the top of the No .5 rear
cap to clear the underhead radius of the bolts.
4. Install the main caps and check for binding or misalignment.
5. Lubricate the stud threads, nuts and washers for the No.1-4 mains with ARP ULTRA-TORQUE FASTENER
ASSEMBLY LUBRICANT. Then install the washers and the nuts onto the studs and tighten them hand tight.
6. Lubricate the underhead and the threads of the bolts for the #5 rear main with ARP ULTRA-TORQUE FASTENER
ASSEMBLY LUBRICANT. Then install the bolts and tighten them hand tight ARP recommends using the ARP
ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT that is provided with each kit as opposed to motor oil.
This is due to higher friction on the studs and bolts as well as inconsistencies in the clamping force of the
fasteners when motor oil or other low quality lubricants are used.
PRELOAD (TORQUE) RECOMMENDATIONS
7. Following the manufacturers recommended torque sequence tighten the nuts and bolts in three equal steps to
110 ft lbs with ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT.
FOOTNOTE: When changing from factory fasteners to high strength fasteners, clamping force and tolerances will
change, therefore it will be necessary to check the main bearing bores for proper size and out of round condition after
installation of the studs and align hone the cylinder block if necessary. The main bores should always be align honed
using the same fasteners and lubricant which will be installed during final engine assembly at the recommended preload.
