Crossfire Reg Rebuild... Possible?

eclecticdialect · 02-04-2019, 03:20 PM

I have and older style Crossfire Reg that I would like to rebuild. Is it even possible to DIY this? I cant figure out how to remove the bonnet. Any tips would be greatly appreciated.

I know I've gotten into one before so I know it's possible. Don't remember what I did but at least replaced some o rings

need to lock the bonnet into a collet if you can. or find someway to grip and unscrew it without squeezing it, or marring it. a set of jaws cut for the diameter of the bonnet, with room to clamp, and a vise would do well also. o'l dummy pip wrench would probably work well too, but, has its obvious drawbacks....

a little heat can go a long way as well.

if you are cool with any machine shops in your area, literally chucking it up by the bonet in a lathe, and using a wrnech on the lower half might just do.....

Some bonnets are reversed threads . Be careful..

Worked like a charm! Put it in a 1 inch collet, put that in a lathe, hit it with a heat gun and wrenched it right off pretty easily... This particular reg did NOT have left handed threads, but it did have a good amount of some sort of blueish/green "loctite". I'll have to figure out what type that is for reassembly.

glad to help. fwiw, i would use blue. blue is for removal with hand tools. red is for removeal with heat. and depending on the exact product, green is retaining compound (to make slip fits permanemt, extra lock on light press fits, etc, i cant imagin eit being easy to remove from threads lol)
