INSTALLATION METHOD FOR MAIN STUD KITS
Part Number: 140-5401 Application: Chrysler 318-440 cid V8
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 into the block “HAND TIGHT ONLY”.
NOTE: LOCTITE MAY BE USED IF A PERMANENT MOUNTING OF THE STUDS IS PREFERRED.
4. Install the main caps and check for binding or misalignment.
5. Lubricate the stud threads, nuts and washers with ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT.
6. Install the washers and the nuts onto the studs and tighten them hand tight. Note: The 12 pt nuts in this kit are
installed on the No.5 rear main cap to help provide clearance for most oil pans. 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 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 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.
