 So we've got a compressor here that is stock and it's from 2001, but because it is a ice cream machine we are going to replace it. Not to mention the availability of the machines are near impossible to get. We've got it recovered. We're going to go ahead and purge some nitrogen through it and we're going to get this thing unbrazed. We've got a new compressor over here ready to go. The new one comes with a hard start kit and everything we need, which we're going to mount that in its own special little box here because the way they invented this here was absolutely asinine. The crap comes right down because people don't maintain the machine properly. The mix will overflow, come into here, trail right down into your electrical compartment here and we'll get into your contactors and all your other stuff. So what I'm going to do is I'm going to put the hard start stuff in its own box off to the side there just to make it a little easier. It's one of the times where it's just nice to have this little box and as much as this thing gets rapid-cycled you're going to want that. We're also going to try out the new Navac 4-CFM cordless pump. We're going to be doing that here in just a little bit. We're not going to do a full-blown chunyum brazen and all that stuff because that's brain dead. We've already done that a million times, but we're just going to do some highlights here and kind of see what we got going on. We're going to get a new contactor in there, new filter dryer and that's about it and then we'll be back up and running because they really use this machine a lot. Okay, I think it's cut out. We're going to have to trim that plastic out for it to fit in there because that's not going to fit and they don't have anything underneath there for that to plug into. So we'll trim that out just a touch, hook these up. We'll use these wires right here to run L1 and L2 over to here and we'll connect that to the common right there. It should be the run. So there's red, so we'll connect to the capacitor. Round up so she's getting into anything. Use the Milwaukee tool there to trim that out. That should fit right in there now. That's not going to go anywhere. Pop those feet on it. I did go and drop the oil out of the other one to make sure that oil was actually in it because this other compressor that had seized up. So I was making sure that the oil wasn't trapped in the barrel or something like that. These do rapid cycle a lot. I did go ahead and clean up my filter dryer area there so when I unswet it, get it out of there. Unswet it? Yeah, I'm going to unswet it because I don't have a crap ton of freaking room and then granted we're going to be fighting some goobers there and stuff like that but we will make it happen. Then they ran five ease if you're lucky and two, it looks like a seven, eight, maybe it's three quarter. I think it was two different fittings here so we can get it adapted. It looks like yeah. So that one there will adapt to it right there and then I think that right there will fit into that piece right there which is great. It's able to put the run in common right on those spots nice and tight right through the Romax connector. So we got a couple of them mounted there. So here's my adapters. This is a half inch so we're going to put that there like that. This is going to bend down to there. That there is going to fit in there like that. We'll raise that shut and then we'll add it to here. Get this thing into place and then we can start getting an evacuation going on it while we're finished wiring it up. Just got to bruise that shut, bruise that, heat this up, let it drop into its pocket and it'll be good to go there. Unhook this, slide a new stem in there that way it's good to go and then add a stem also to this point right there. I'm trying to keep everything closed up until I'm ready to get busy. My very last thing I'll be doing is my filter dryer that way you keep all your capabilities of keeping the moisture out to the minimum. Got that undone. Getting ready to burn that one in. Got the filter dryer out. Just got to get that into place yet. And for the nitrogen police, I do have the nitrogen there. I purge through. You know you can like do so much on certain parts there but we're getting it with good practice as best as possible. I don't want to purge anything that's left in there and get permanently bruised in there. So I had some problems trying to get that in there which is why I hate reusing anything. It's bruised because you got to heat up your base metal down here on the filter dryer. You got to try to get it in there and then the flash dang dang didn't freaking cut it off square. It's oval shaped. It's not going in there. Say the least. This piece back here broke off. This one here as I'm trying to pull it apart, snapped apart. We just redid it all. We're doing with a 3-8's T here with a piece of 3-8's of the sleeve. We're abushing and it's going over to that piece there. We're going to go ahead and purge some nitrogen through there and then brace that thing up and then we can probably start pulling vacuum here real soon. All right another shameless ploy here for refrigeration technologies. Never used this stuff before either. John sent us to me. Wanted to try it out. I've tried the other stuff too that it does fairly good to. But what I noticed about this is it's really formable and it's easy to form. Now let's see if it actually is worth a squab when I'm done. Make sure you know that it don't take off the paint. Let's go ahead and burn this thing in and see what we get. All right so it held up pretty good. It's a little little uh lacking there but I think I can pick that out of it. But it seems like it did pretty good job. It protected everything. It never got really hot down here. Cooled the section down just a little bit so I could inspect it and it looks like everything pretty much went in there pretty good. It seems like it's still pliable which is good and uh that's that's what I was looking for. Something I can still reuse and throw it back in there. I'm pretty impressed. That was definitely easier for me to um form it to get it on there. Usually I can't can't get it in there uh with some of the other brands. I mean not saying the other ones aren't good. I'm just saying that they don't form very good and usually filter dryers I just go ahead and burn some of it because it's such a pain in the butt to try to get it to form around it. Cleaned up um there's a little bit of damage there but I did not put it on very thick because you've got to be able to get heat onto the base metal there to pull it into the socket. As you can see I got from here to there and uh seems like it pulled in pretty good. You're gonna have a little bit there no matter what and it's inside so it's not exposed to the elements. Looks pretty good. We did our pressure test here. Found one little leaf there. There's some silver solder on there from the last repair. I had to reuse that little piece of copper there. He did it up. Added some new uh rod to it and everything's looking good. We're gonna go ahead and get this thing vacuumed out so we're gonna get the nab back of course to get them back pump out. We're just gonna pull off this thing with the uh blue hoses. I'm gonna put my micron gauge here on the high side and we're gonna put the hose there on the suction and pull this thing down. We got the four CFM vacuum pump here. Comes in a nice little gym bag looking thing here. It's got a shoulder strap. Got the velcro strap here at the top. Gives you a lot of room in there. There's a charger that would normally go in there but I haven't been carrying it in there. So let's get our battery on here and see how this thing does. This will be my first pull down on a live unit. Granted, it's new oil and stuff in the compressor so it's not gonna be bad. We've got a brand new oil there. I've already done a test on this pump when it first got it and it pulled down I think 10 microns. We have the 9 amp hour battery. Just hooks right on the back. Oh just like that. It's got a half inch. This is something the two CFM did not have. It also has the ball valve there that the two CFM did not have. It also has a gas ballast on the side that the two CFM did not have. And it has an eyelet here so it's got some extra goodies on it to make your job a little bit easier to make your oil last longer. We're gonna go ahead and get our big blue hose hooked up here on the half inch. We're gonna pull on the suction side here and we're gonna measure our microns over there. All right let's go ahead and start the stopwatch. Turn this thing on. Super super quiet. The exhaust actually comes out through this little handle piece right here which is kind of interesting. Let's start to see here where I started to come up to speed. I'll go ahead and start my gas ballast open. There it goes. Now I do have a place to plug in available. I want to see what this thing can do and they say you can get quite a few evacuations off that one battery. I'm gonna get you a little look at this thing. It's got a plastic bottom on it underneath there. Underneath there the electronics are in there so you do not want to set this into deep muddy water or anything like that or you're gonna fry it. Other than that I mean you've got your oil fill right here on top and your oil drain right here on the front which is pretty simple. She does get a little bit warm after runs for a while but look what we are already. We are already at 4,000 microns. We're at a minute and 40 seconds which I'd say a minute and a half that was actually some of it. This is a 12,000 VTU compressor so it's not a little toy for being a small client but you can see the leak rate how fast we're actually removing the air from inside there or the pressure from inside. You had to double the CFM of what they have before at 4 now instead of 2 which even the 2 did good from what I've been told but the key to everything right here is the big hose. Having that half inch hose right there is I think key. You also have your quarter and three eighths so you can get both sets of hoses on there but I'm pretty impressed so far we're really hauling it down and you gotta remember we're pulling through the suction side here on the compressor so we're getting the whole case we're having to pull backwards when you're pressurizing the system you can actually bleed through the suction side and go through the compressor to kind of like go right on through because the valve is pushing down through it and coming on out so when you're pulling a vacuum it's not going to allow it so what we're seeing there is actually coming back through the TXV and everything else so we're getting a true sense of what's going on. We're at 3 minutes 30 seconds I would say more close to the 3 and we're already at 1100 so wow that is pretty impressive so the battery life it's not going to take a lot I've never timed it and let it run non-stop but I've heard somewhere around an hour is what they they have if not leave it down below and if I find out that I'm wrong I'll leave that down below also 0.5 0.4 guys you can pick this Navac vacuum pump up it's TrueTech tools use discount code survival for 8% off put that in a checkout I'll put a link down below also for the Navac tool along with some of my other favorites we are now at 800 microns at 4.5 minutes not bad when you're pulling against the compressor oil and everything else which you know it was open for just a short period of time so you're gonna absorb a little bit of moisture but so far so good I'm gonna go ahead and get started on my electrical over there this is kind of short so I'm not sure I may have to mount it over here which will make it easier for me to work on it in the future it'll also allow me to keep that out of any drippage because you've got the rear of the barrel here which if it leaks it comes down gets onto this plate right here and then goes on through we do have a side glass which you can see is already pretty green it was starting to get a little yellow from being open for a while but at five minutes we are at 700 microns not bad and only pulling with one hose you would have never gotten that out of your quarter inch hoses no way we're kind of stalling out here 20 minutes we've been under 500 for a while let's go ahead and kind of get that air bubble out from underneath that ball and see if this thing will hold you see it already had a little bit of a effect on that oh baby keep dropping on down there for me got your power coming in here l1 l2 loops up comes to the bottom of the contactor it parallels off to the drive contactor this is for the drive motor mixes everything common coming off of l1 to one common side of the 230 volt coil same thing with this one right here we got the top here being fed to the compressor which goes down over to there we went through this little spot there which would be good that's going to keep all this crap from getting screwed up when next drops down from above getting rid of the other contactor we're using 40 amp contactors here because they're heavier duty this thing will rapid cycle over the year it may cycle up to 50 some thousand times you got to use the heavier contactors and these are rated for 40 amps so we got that we did a valve off test here and you got to remember they're about 680 we're holding it 0.7 so it slowed down you've got refrigerant in here you got refrigerant in the evaporator we're not going to get a perfect vacuum with this right now but i know that we are not moist i know our moisture indicator looks good i'm not going to spend indefinite amount of time here to get to it if i was probably a digital deal it would have probably passed it we're pretty good here i'm gonna put something to help isolate that from the metal from vibrating otherwise we'll strap up our wires here and get this thing charged up okay you're probably wondering how i did it so without the bow there so i'm just putting a little bit of liquid in there a couple ounces we're gonna let it boil off the pressure's coming up as soon as we're in a positive there we're gonna take that off and finish charging the rest end liquid through the discharge line switched it over now we're charging through discharge line this holds 27 ounces that was with the 083 but only had a 163 dryer so we're going to uh have to add probably about two ounces to an ounce and a half for the dryer not a humongous deal everything's looking pretty good nice green sight glass there so just about there that would be one pound 11 ounces we're at one pound 13 so i have two extra ounces there just uh gotta get our panels back on gotta finish uh it's securing a few things here yet we got that mounted down got tape on those that's not even touching now it's lifted up off of that once i got that in place just need to uh get some mix in this thing and see if she makes a milkshake we've got her filled up let's go ahead and plug this thing in see if she throws sparks turn away oh there's that all right put this thing on she's free she just came on good deal she's a pumpkin sight glass is staying full head pressure should stay somewhere fairly close i think the water's still on ah that pressure seems a little high are we not getting rid of that but that valve ain't doing so good is it she's getting her up there 150-ish 250-ish it's 105 she might be slow to respond usually about 235 so it's coming back down that's good got a little bit of flash in there so we may need to give it a little squirt i don't seem accurate what's going on oh here we go there we go boy you want to talk about scaring a crap out of you okay there we go it's actually looks a little bit better run about 100 degrees not so bad there on that looks like we're fairly fluid we got a little bit of a bubble there i'm going to give her a couple extra ounces she's sitting charged by the sight glass but like i said since i ran a little bit bigger filter dryer in there i'm going to give it a little squirt or two extra just in case a nice warm there i gotta grab some wrap insulation for that real quick so far we're looking pretty good run right in there about zero not too bad just added uh looks like i added about four ounces over total then what the original factory was this machine is uh 20 21 years old it was probably due to be replaced but machines aren't available so we just have to make it work get that wrapped up wire tie help hold that support it so there's no vibration which were kind of i always like to see my loop more towards where the brace point is it just tends to vibrate less seems like when it's in the middle it tends to vibrate more since the south they're slanging she just satisfied we were running 235 sweetness gotta go ahead and disconnect and uh double check our product here real quick let's milkshake there you go works might need to adjust it a little more but for right now it's working so that one's done well guys let's gonna wrap that one up pretty much uh wanted to show off the vacuum pump and what it can do you know instances like that where they've got refrigerant in the uh oils and things when i pulled that oil out of the compressor that was in there there was still quite a bit of refrigerant trapped in it and you know it it actually fooled over the cup when i poured it into it so that that refrigerant gets trapped in that oil and it does not come out right away and the same thing can happen with the you know anything else far as you know in the barrel and things like that you'll have oil trapped in that and it just doesn't let it up and all you're doing is you're getting boiling off now there's also the chance too that your valve core tool is not holding i've got a chamber that i built to pull against and i don't care whether they've accumulated they're vacuum rated when they're brand new not when they're been used 50 times and they wear out and you can rebuild some of them but i've had them still leak so you know i don't have a lot of faith in some of these valve core tools and i don't really care who makes it tnd's been the best one for me i've tried the other big names and stuff and i just really like the cnd that's what they were using at the stolding factory figure just good enough for the people make the machine that i work on all the time it's good enough for me so i've tried all the other ones not saying one way or the other on either one anyhow that thing's running good made a milkshake great you know machine's old it's wore out i did clean it up made it look as good as possible uh put that oversized dryer in her not really because i wanted to but because i didn't have anything else to use and everything worked out good for it that's just a quick video just thought i'd give you a rundown of the four cfm nav bag a vacuum pump and as always you've got to use the right size hose if you're wanting to see any progress in that once again guys don't forget i once again guys don't forget the promo code survival at true tech tools true tech tools is partnering with me on a lot of different
