How many times can you use ARP rod bolts?
As long as the fasteners have been installed and torqued correctly, and show no visible signs of damage, they can be re-used. If they show any signs of thread galling or corrosion, they should be replaced. In the case of rod bolts, if any of them have taken a permanent set and have stretched by .
What is the torque on rod bolts?
In the end, you’re better off using the proper lube and torquing the bolts three times, rather than doing the torque-angle method, but it’s still not as accurate as using a stretch gauge.” Theory: At a certain torque reading, the rod bolt will achieve the designed stretch and preload.
What size are ARP rod bolts?
ARP head stud bolts are 6 pt.
Do you have to resize rods with ARP bolts?
Changing rod bolts should not require any rod resizing as long as the they are the same dimensions and the correct torque is used.
Why are ARP bolts so expensive?
ARP stuff is typically more expensive than other brands, but again, that’s because they use more expensive materials, and the manufacturing process, from heat treating to machining, is more involved.
Can you reuse connecting rod bolts?
Like headbolts, you can reuse rod and main bolts assuming they are in good condition. Check them for excess stretching at the threads and where the head meets the bolt shank. Bolts are inexpensive, though. If you are intending on making a lot of power, consider new or upgraded bolts/studs.
How are ARP bolts measured?
All ARP connecting rod bolts have a small dimple placed on both ends of the bolt that accurately position the rod bolt gauge pins on the bolt. Next, zero the gauge on the relaxed bolt. Then you carefully tighten the rod bolt until the gauge reads the appropriate stretch amount.
How do you measure ARP rod bolts?
What are ARP rod bolts?
ARP Pro Series connecting rod bolts are precision CNC-machined to exacting specifications and designed for optimum reliability. They are heat-treated and threads are rolled to provide up to ten times more fatigue strength.
What is resizing connecting rods?
To “resize” the rod, the bolts are removed, then a small amount of metal is ground off the rod and the cap where they mate together. Then the bolts are reinstalled and torqued in place. Because of the metal removal, the big end is now smaller than when you started.
How do you install ARP rod bolts?
How to install ARP connecting rod bolts
- Disassemble and clean the rods (including bolt and beam threads) to remove rust preventative.
- Apply ARP Molylube to the threads and under the head of each bolt.
- Assamble the rod to the piston.
- Install rods by bringing cap and beam into alignment.
