Oxygen reg rebuild

yeah well show you I got a problem with my oxygen regulator I just want to show you what it's doing this is the old regulator said I got back over 20 years old whatever I sent my turn my ox is you know on sometimes it's it's holding fine but it's been creeping up on on this side here right now it seems to be working fine earlier this week it actually it actually pumped to the relief valve on here whatever if this error gets too much pressure on if there's a relief out here and so it was actually popping the relief valve so I'm gonna pull it off here take it apart I got a kit for it and I want to show you a little bit about how these how these work and how to put a new kid in it okay I've got to set up hearing advice i clamped on the back slide there the manual says when you pull it apart you're actually supposed to pull this out first this is your adjuster yeah a little worried about oxygen I'm not a lot of people know this but if you actually contaminate the inside of this regulator with all and I'm wearing gloves because it's pretty sensitive to the oxygens very high pressure oxygen is very sensitive to oil what we've got here we've got a light out in the order of use here you got the t-handle adjuster you got the cover this spring actually that part right there when you tighten this end adjust your pressure up it actually pushes against this spring I've got a washer goes around the diaphragm and you these are usually stuck in pretty tight I've actually already assumed or disassembled this one to see what was going on with it this is the new this is the old diaphragm I've got a new kit that has those parts in it but this side here is actually the low-pressure side of the regulator high-pressure tube comes in this side and that's connected on this side of the gauge and this is the valve seat and I'll pull that apart here and we'll take a look to get out there to clean your wrench out good before you actually use this like say anything inside this regulator you should keep grease free I wouldn't even recommend using the flammable cleaner I think if you need to wash it out I'd probably use soap and water if it were me this one's fairly clean but if you actually spray a flammable carburetor cleaner something like that in here and there's a residual if there's any residual fuel inside of here when you turn that bottle on it will cause the fire inside this regulator or where it could explode I never have a witness that happening I don't hope I hope I never do but anyway like say if you're gonna do this a new regulator is probably 100 bucks for a good one this kids 20 and Victor's you know they were built to last especially the older stuff and it's a shame to me it's a shame to throw this stuff away when you can rebuild it get some more life out of it so that's one reason that I am rebuilding this one I don't want to throw it away I don't want to go buy a new one don't really need to okay there's a little I'm going to show you what comes in a new kit be the description here but okay this is the repair kit I got online and what we've got is a new this is a new seat and you can actually take this apart that it unthreads off of the top here but you don't need you don't want to take that apart if if your old one or if yours looks like this where it's all frazzled that's pretty good in indication it blows it you know there's too much pressure blew it up so the new kit comes this Park this is what it should look like on his mood looks really shiny and tough you got to remember an oxygen bottle has 2,000 psi on it or sometimes more than that when some of the bottles are filled and so that little seater up there has to handle to all that pressure and this spring here has a little nylon slide and this is this is just kind of like a a guide for that little rod so that can move back and forth without binding up the kit comes with a new one that's that part right there but really the only kit the only parts of kit comes with is the new what do they wonder if though I get the technical term here for that this is called the seat assembly actually and this is called the nozzle so we got a seat assembly we got a nozzle and locks I needed I need to clean that be sure there's no bumps or frozen in there and I'm gonna be soaking water clean it up and then I will put it all back together here in a minute okay so I downloaded a following rebuilding these regulators I'll try to put a link to this is for the victor but what we got to do is assemble the we're going to assemble then this is our new part we've got with the kit we're gonna put a spring on here this little spring retainer has a groove in it that fits inside the spring then there's a little bearing type deal here and what this does this rides in the bottom of the regulator and it just it just wants to it keeps everything in line so that when this opens and closes it it's always straight so we want to put that together like so be sure there's no oil on your fingers I cleaned this out soap and water and you know we're we should be be as clean as we can get it clean it with soap water blow it out with a little bit of air you know one be sure is not a little you know will the air you want it to go through a field regulator also have this washer it's called the nozzle order and I'm actually gonna put that in there upside down the torque on this is 16 to 20 foot pounds actually I'm gonna have to put the nylon washer in there first and then [Music] sixteen you're 20 inches you have foot-pounds is what that says tighten that to 16 to 20 the pounds on that so that's torqued I've got hopefully clean hands here everything should be clean but now we're ready to put in the diaphragm this is a new one that came with the kit and we've got a washer and it goes on top of there the next thing we've got is our spring and our plate that rides against our adjuster and this will be centered up by this cap whenever we put it down on there it should Center everything up and then unless I'm forgetting a part here that's pretty much it there's not a lot of complication to these these little victor regulators are pretty simple locks they don't use any all if you if you use if you you ever take your gauges out and put anything on them just use a teflon tape the only don't even use a you know don't use anything that's oily like a holy pipe dope or anything like that you just don't want the you don't want to add any fuel in here with this oxygen when it comes in under first so now of course the oxygen or the acetylene regulator would be a little different deal wouldn't be quite so sensitive but with that being said I would probably still use the same precautions just you know it's not that big a deal that keep everything clean but I'm going to torque this down I believe this says forty to fifty feet forty to fifty foot pounds on the cap here and I'll put the adjuster back in we'll put it back on the bottle and and test it that the actual book says to test these with a nitrogen bottle and I don't have a nitrogen bottle I don't want to get one just to do this test but I do have a full oxygen bottle so I'm going to go ahead and do this test on on the bottle out here the oxygen bottle now if I did everything right it shouldn't have there shouldn't be a problem putting it back together it should work we'll go through the test once we get it on there and our our first test is going to be the creep test you're going to slowly open the test valve with the test gun closed adjust the regulator to deliver the appropriate pressure listed below so we're gonna set this to five range one is five psi and that would be like our first mark that's like five psi there now we're gonna open the test gun stabilize our test guns young bear torque seems to be working and we're gonna says to observe the gauges for five minutes during the first minute slow shut off delivery rise to the seat not closing quickly enough should not exceed one PSI during the next four minutes no creep is allowed so this if I test this for a minute at five psi should not go up it may go up one pound but no but no no more after that for the next four minutes and then her next of course our next test pressure is 10 pounds same thing blow the locks again through the hose here and we'll watch the gauge see if it creeps like I did get a slight increase there looks like it so pretty good I'll go ahead and crank it up to Tony here and there's a leak test okay the leak test is you're supposed to crank this up to the maximum pressure [Music] but that's about 120 pounds now I'm supposed to close this [Music] we're like leaf I may need to take it apart and clean it okay if I said it 280 pounds now I'll close this off we shouldn't have any leakage through this gauge here it's holding pretty good okay and when these regulators are working right you should say you should build water it's called a drop test if I set my regulator to say 10 pounds [Music] okay if if we set this at 10 psi and we open our air flow we should not drop more than 3 psi here so I'm gonna open my oxygen wide-open I basically didn't lose any psi there seems to be working good and our next test is up to 20 psi and shouldn't lose more than 4 psi whenever we open everything up a little bit regulators working pretty darn good I think [Music]
