Reviving this never-ending great thread.

Most everyone here likes using Loctite 574 on the main bearing webs due to its additional shear strength it adds, especially to unpinned mag cases, aiding the cessation of chatter which occurs in these things. I cannot say how successful 574 has been in helping these situations or not, hopefully someone can chime in? Anyway, it was brought to my attention by a Loctite rep that a low or medium strength retaining compound such as 509 would actually be a more appropriate for this particular application. Tensile strength of 509 on aluminum or mag is about 40% stronger and it is also anaerobic. My concern would be that because it's stronger, how much more difficult would that make for the case to come apart again? Don't personally know how difficult it is taking apart a case treated with 574 on the webs, but we can say it might be a bit more difficult?

My shop is very near Road Atlanta so we have all manner of reps going through the area and I happen to catch this gentleman today at the machine shop I use and we discussed the topic a bit. Just a note re an alternative and if anyone cares to comment.
