ARP damper bolt procedure
Ready to install my new ARP damper bolt. It didn't come with any instructions, but I seem to recall that the torquing sequence is not the same as the OEM bolt.
Loctite required?
Checked ARP's website and did a search here, can't find anything.
Anyone know?

Using their moly lube - 196 ft lbs
Using loctite - 235 ft lbs
Using 30 Wt oil - 247 ft lbs
This is after the balancer has been installed and seated per the manual.

Most people using Loctite? I think I have some blue kicking around, not sure about red....
My service manual doesn't call for it (using the GM bolt), and the torque is similar, so not sure.....

It seems many do. I'm not one to follow the forum crowd, which is why I called ARP for info. Also, I pinned my balancer.
That being said, both blue and red threadlocker are adequate for the diameter of the bolt in question. Blue is removable with hand tools. Red comes in two flavors, both are high strength, and
one is formulated for high temperature. If you use red, you will have to heat the bolt to remove it in the future.

As stated, use the ARP lube. There are a couple of guys at ARP who you used to get on the tech line but not very often now. One of them told me if he had a nickel for every time someone called and had used Loctite on their bolts and was now having issues he could have retired.
I would use the ARP Moly Lube, which is how I installed mine and what ARP recommends. To date, no issues. Then again, I measured to ensure the interference fit was within specifications.
Also, as a by the way, Loctite has a shelf life so if it is "kicking around" you should check the date. I chuck mine after two years.

The 240 lb-ft is based on the friction developed from their ARP lube. If you use something else, you need to correct the torque value. Fortunately, for Loctite (per ARP) you can use the same value. Just information for the future if you need it.
