Removing maxflow

[Wizzman]

Hey guys I have an inline maxflow reg on my crossfire tank and need help. My on/off valve on my reg won't turn the reg off and I need to replace the o-ring in it. Thing is I have to take the reg completely off my tank. What is the easiest way to take the max flow reg off so I can rebuild it? What tools can I use to get it off and what kind of tool could torque it back on there? Because the max flow reg is a cube shape. Thankx for you help guys...

Hey there!
Welcome to the hell that is the Maxflo on/off :cheers:

I recently sold my inline to another fella who said he was up to the challenge, and have gone back to the good old crossfire red HP preset reg. :cool:

Anyway, sounds like your tank is loc tighted (I never know how to spell that). I never had mine loc tighted so what I know about removing it is what I have read about. Mostly two strap wrenches and a heat source.

Well once you get the tank off, you will see a small set screw below the threaded stem. That thing is what holds the on/off into the regulator. It is the absolute smallest allen wrench I have to take it out, I have no idea what the size is other than standard (my allen wrench set is from WWII and the labels have worn off along time ago). Once the setscrew is out you will have to slide the on/off out of where it is (just pull it out, its in there really snug so use something gentle to pry it out with). Once it is our you will have to look into the shaft that it was in. about half way in, there is a o-ring that is in a small hole perpendicular to the shaft. You have to pull it out because that is the o-ring that it screwed up. You will have to use something like a pin or a dental pick to get it out because it is so small and oriented in such a strange position, a magnifying glass and a light really help too. Well one you get the o-ring out inspect it and you will notice a small notch that has been cut into the o-ring. What caused that is that you turned the on/off while there was no back pressure on the regulator (maybe you were shooting it as you turned it off or you had a leak or something) and the tank pressure forced the o-ring onto the on/off post so hard, that the little hole on it cut that o-ring like a chisel. If you look inside the hole in the on/off post you will probably find a small chunk of o-ring in there (it’s a good idea to take that out so it doesn’t get into your valve). Well once you have that all taken care of, put a new o-ring back in there (you should have at least 1 in your spare parts bag that came with it), screw the reg back onto the tank and air it up. Don’t loc tight it again because TRUST ME, it will not be your last time.

EDIT:
you dont have to torque the tank back on... just screwing it on by hand works just fine. Once there is pressure in the tank it will be real hard to remove it.

Good Luck

Hey bro thanx a lot for your help it is much appreciated. Mine is not locktighted (lol sp). So I guess I can just use a strap wrench. I thought it had to be torqued on there but if you say by hand is okay that sounds good. Also what is the easiest way to keep that o ring from being cut like you say? Because I have seen that this is a common problem with these regs.

Sorry to say this, but I think the last run of these things were all defective. I could not find a way to keep mine from cutting those o-rings.
I know 3 other guys localally that have them and all of us have reluctantly moved on. Its too much of a hassle and it seems like it just gets worse. I seriouly only got 1 tank of air out of mine before it ate it. Then after that it was hopeless. I used that reg in a whole 1 game. :cry: It is really too bad I liked it when it worked for 30 seconds, It looked great on the gun, and not to mention it was $$$. After $50 of o-rings for the thing I finally said forget it.

Sell it. and put a preset back on that crossfire bottle (they are the best)... thats what I did.
I will say this was the first time I was truly dissapointed with SP, and it was enough I won't buy thier products anymore if thats all the r/d they put into things. Sorry SP, that was an expensive screw up, you should have recalled it.

Hope you can get it to work. there are some mods that claim to solve the problem... but there are some other little gremlins inside that thing I didn't want to deal with.

Hmm well that sux. I still have a blank warrenty card so I may just send it in and tell those SOB's to fix it. This is the first smart parts item I have owned and I am not liking them so far. All I want is to be able to turn the darn thing off lol...
