 All right, we're back here to do the change out of the headmaster here. So we've got it prepped, ready to go, recovery machine ready to go. Have the tank here just finished pulling it down. Got it in a vacuum. Pull right off the receiver. We've got power killed. Silinoid is inside. So we're liquid all the way from here to there. Pulling through my three eighths hose. I'm gonna let it just naturally go on through. We'll start the pump here in a second as soon as it slows down. We'll re-weigh our tank when we get done, but just kind of getting the prep to go. We're planning on chopping out the service valve here. Sultimately do we ever use them, but they definitely cause enough problems as far as leaks. As I talked about in the other video, a lot of this oily looking crap, it probably came from just mainly that, but if that's the case, I don't know, it's just no other leaks were found today is back to 14 degrees area. So we're not gonna spend a bunch of time out here. We're just gonna get the headmaster replaced and move on. Gonna yank off this panel right here to make it easier to get into. Now we'll be able to get in here nice and easily to these two components that I wanna chop out. Getting a better look in here, kind of see. Oil and residue are on the side. It's really hard to say. With this temperature, that pressure's gonna be so low. We could put nitrogen behind it. Chances of getting a coil, thanks to all the production that's been cut. Now we're kind of half time lucky to even get a condenser or a new unit. Otherwise I'd push for a whole new unit. This one here, 2011. So we're 10 years, 11 years old. It would not surprise me if it's not leaking, but at this point, what do you do? It needs to change out. Gotta get it going. Not a perfect world. Kind of boiling off there. Chug of luck, baby. Looks like we got the liquid side taken care of. Got to hop on the suction. That glass looks like it's still kind of old, but you'll see it's boiled off. Got a new dryer for that, we're gonna swap that out. Gonna have to sleeve this. Unfortunately, these were half inch valves they got. As you can see, you have the LAC4DS100-180. Well, unless you specify what size, it appears that you gotta sleeve it otherwise. Which kind of sucks, because that's more work that you probably didn't have to do if you would have gotten that one. And you just got one marking there on it. Well, that side was pulled into a vacuum too, so it must have either called, which I don't believe that solenoid's powered by anything inside. So I would say I just sucked it in reverse and got it through. We can go ahead and start cutting things out and we'll sleeve this. We'll just use a piece of half inch stub copper in each one of those. So like I said, we ended up just getting some half inch pipe, marking it, cutting it. Bring it out. Got it ready to go. Got a piece of three eighths there for our quarter inch sleeve. They do make nice bushings for this, but obviously I don't have that with me today. You could try cutting it out, but I'm a little short on length here on pipe. So I'm not going to. I'm just gonna undo it and pull it out of there. No splits, never gonna go. Just gotta do a couple repositions. So cold out here, my hose has barely been on my hose, it's on my torches. It did put some nitrogen through it. I'm not running it currently right now. I'm gonna put that one off. Place them there before you fold apart and you're less likely to get your flashback off of the oil that could be trapped in there, especially when it's not feeding correctly. Got a little bit of oil stuff in here to catch on fire. They'll have that on these big jobs. A little bit of prep work makes all the difference in the world of this stuff a little bit. Really there's no reason for it to have been there to begin with unless there's a pair made. All right, so we've got our prep ready to go. Pretty doggone close, not a perfect fit, but it's straight, everything's in as far as it needs to go. You can see they actually did the same thing with that one there, but we've got that ready to go. We've got our dryer here to get back out. We'll put that in at the very last minute so that we don't have a hit absorbing moisture. This one here might be a little more difficult just because we got to pull that loose so we can pull it out, but other than that, it shouldn't be too bad. I did put some nitrogen through it. It'd be nicely flowing, but at this point, we're just gonna have to call the nitrogen fleece and have them give me a ticket, I guess. I did prep my metal, which is critical when getting this as quickly on and off as possible. Let's bite first, pull into it, pull into it. Next one, pull into it. Bottom, and from this back side a little bit. There's your stiff, not wanting to let it move. Up hill, my favorite of all things to do, same deal, keep that base with the medium top one, pull that crap right up hill. Not the funnest thing in the world, but you can do it. Do this like that. Too much heat, y'all goes to crap. Same thing here, let's get that thing pulled up in there like that. Pull her up, capillary up, baby. Looks like I got it. We're gonna cut it here that way, we can swing it in and out. Raising it up and down is not gonna be as easy to do. And as usual, electricians have got their freaking wires right in the damn way. We got this out of there, all I had was rigid copper, so I went ahead and heated it up with a hand torch, cooled it back down, bent the 90 on there, turned out perfect. So now we're just going to form this up here and then swedge it, we'll have to heat it up again so I can swedge it there, but the key seems to be just to pull it down, then run it through the swedger and you're fine after that. We should be good, we're gonna go about right there. Nothing in there, you can't see it, but believe me, I seen this done on YouTube, so it's gotta be right. We'll heat that up, slide it up in the hole, and just like brand new again. Using my rubber end there so I didn't bang the lid and snot out of that pipe. Of course, you know, this costs a lot more than what they're all piped in. Shoot that from the bottom, get it sucked in there, try not to burn up the freaking conduit here, it's in the way. We got that cleaned up, not too bad. It definitely wanna make sure you cool that down before you run that through your bender though, because it will melt those shoes if they're made out of plastic like the Hillmore is. Only thing we gotta do now is get the filter dryer in there and go ahead and get her under a pressure test to make sure nothing's leaking over here. All this cleaned up pretty good, doesn't look too bad for what we had to work with. It would have been nice if it had been the exact same diameter and it wouldn't have had it full with that, but just the way things go sometimes. A little dot's still green, nothing was overheated, it's so freaking cold out here, that thing cooled down so fast, it's why I didn't wrap it. Gotta take that freaking fan cycle control out of there yet, pull it back on it after we do the pressure test and see what we got. Just got the pressure on there, we got 265 on the high side, still waiting for the low yet. I have a little leak on the back side over here, but if you can't see your work, because it's up here in the freaking ass air and you can't get to it, you will probably have a leak. So, how to get the ladder out, get to that. I'm gonna head and spray some of this down. I'm gonna get my ultrasonic out and see if I can hear it. These are like a nice solid stream now. And like I said, it's 14 degrees out here, so that's big blue, it's not the low temp stuff. Only a certain amount of time until it starts to freeze up and wouldn't bubble anyways. I'm not hearing anything. If we have a leak, we would've caught it, I don't hear it. I got the fan cycle control out of there, that's all back to normal. Everything's sprung back up, we can just pull our vacuum now. You guys know I love these hoses, but when you're in this 15 degree weather, how anything below probably 50 degrees, these things turn into freaking harder rock thing. They don't do not move at all. I'm just trying to speed it up to no reason why I'm doing it like this with these, because it's just faster. Sounds like the Manics Walk's having a bad day there. Yeah, motor's going out on it. So anyhow, the vacuum's pulled or bled all the way up to our hoses. Got our zeroed out there on the scale. Let's just suck it in as much as we can. We're just kind of way it in and see what we get. It's going to be usually a real treat trying to get this refrigerant back in there when it's this cold. It just does not usually want to go back in. Get that out with negative. I think we added like eight and a half pounds or something like that the last time, so we should have at least that amount or more. We'll see where we're at here. We're going to let it naturally get in there as far as we can. We'll suck the rest of it in. It took eight pounds and a half in so far. The unit's turned on. You can see it feeding. And the suction pressure's coming up there about 19 and rising, so it should kick on here in a moment. But we'll see where we're at, see if we can pull the rest of it in. Worst case scenario, one of the little tricks you can do is pump it down and then that way the suction drops even lower. Cyclists, so far, is full, which is good. Hopefully this thing's feeding right this time. It'll take a little bit, of course it just shut off. And it's coming back up again. It just, that initial startup takes a while, a lot of times. Yeah, it's so freaking cold out here. There it goes again. I'm going with the upside down tank just because of the dip tube. I did want to deal with it. I wanted as much flow as I could get. And so that was kind of the reason why I did it the way I'm doing it. All right, so we're warm there. Warm there, which is good. And it feels like it's fairly warm there. Yeah, it's definitely cold at the bottom, which is good. And I've got more heat coming out of the top. So she is feeding correctly so far. Head pressure, 150 and rising, which is good. So we're already on the right track. Looks like we've about got the last of our refrigerant in there. So it probably didn't have a whole lot in it when I did it. We'll see if we can get the rest of that in there. It's still flashing some. Now that everything's feeding correctly, they should go get this where we need it at and we'll get the final charge set up. Got her valve off there, just easier than getting to the receiver. Pulling that last bit in there. See if we can get it all out of that way. We ain't wasting any. Suction's not quite dropping yet. Still got the valve core pulled out of the suction sort of valve there, so that's still going to allow it to feed through pretty quickly. The most part though, it looks like we're holding pretty steady on the side glass. It's been holding full the whole time. I might add an extra pound or so just to make sure we're at close to the 80% mark. End up being right at nine and a half pounds that pump down shut off. Let's go ahead and heat this up and see where we're at. Got the thermal imager here. We'll see where we are. I'm gonna mark this down on our door wherever I put it at over there and that way we'll have it for later. Okay, as you can see, we are right in there. Let's see if I can hold this three things at once. Is where it's at. We are at probably about 65, 70%, which I'm pretty good with that. Yeah, that's not too bad. Go ahead and rip this thing loose again and see where to watch our head pressure control there. Okay, you can see it. See the hot gas coming through the bottom there. We're going right into the valve and you can see how we don't have anything really coming out of the bottom of it. So it's coming in the top and nothing much coming out of the condenser at the bottom. You can see it's feeding through. You can see it also there where it's going into the receiver. It's warmer there than what it is coming out of the bottom. Now to kind of give you an idea of how that's feeding, you can see the whole bottom half probably bottom quarter of it's not feeding. And a good portion of it to the left is not. I mean, it's feeding, but just the heat's being held back and being driven into the receiver to keep the head pressure up. All right, I got her all back together. Got the clock, defrost clock set up. It's just about ready to go through a defrost, which it's shut off and satisfied. So I'm not worried about it starting over for that. We already checked for leaks. We've got all the leaking things out of it. Appears we should be good for a while, marked it held nine and a half pounds and all the other equipment is verified to be on. So we should be good to go.
