62 800-826-3045 Red part numbers indicate new items MAIN STUDS MAIN STUD INSTALLATION 1. Clean and chase appropriate threads in block to ensure proper thread engagement and accurate torque readings. 2. All hardware (and caps) should be cleaned and inspected prior to installation, looking for any shipping damage or defects. 4. Install main caps, checking for binding and misalignment. Lubricate threads, nuts and washers with ARP Ultra-Torque fastener assembly lubricant before installation. Have the block align honed. 5. Following the engine manufacturer’s torque sequence, tighten the nuts to the recommended torque value found on the instruction sheet provided with each kit . There are a number of important considerations when install- ing ARP main studs. First and foremost is making sure the block and studs are as clean as possible. Foreign matter and debris can easily affect the quality of thread engagement and cause erroneous torque readings. Do not re-cut threads in the block – use the special “chaser” taps as listed on page 128 of this catalog. This will preserve the integrity of the threads and pro- vide better engagement. Calibrate your torque wrench – even new wrenches have been known to be off by as much as 10 foot pounds! Use consistent tightening techniques. 3. Screw studs into block, finger tight ONLY. For permanent installation, apply Loc-tite (or similar adhesive) sparingly to threads. Be sure and install the caps promptly before the cement sets to prevent misalignment of studs in block.
