 This video is brought to you in part by TrueTechTools, quality tools, essential support. What's going on guys? So today we have got a cooler. This is a two compressor unit that's two separate circuits here. I was here yesterday didn't have enough time to finish everything up and because of the lower temperatures out we're able to secure it overnight. So let's take a look at what we had. So what we got going on here is we had an oil failure on this compressor here on the left. This one right here as you can see we had oil all over the place. I picked up some leaks here on my cyclast. I ran some brake cleaner on it to clean some of the oil off and I went ahead and pumped some oil into it but because we're low on refrigerant I decided to just shut it off because it was short cycling and even after jumping 24 pounds 25 pounds of 407c in there it still wasn't making a dent in the operation. The cyclast looks awfully empty and so we've got enough time now we can get started on this thing. This thing's taking care of some pretty big walking coolers multiple evaporators in there in that same section. Let's go ahead and get this other door off and let's start seeing if we can find out where this leak is coming from. So I'm contemplating possibly valving this thing off and pressurizing the compressor because I truly believe that my leak is in the compressor. The pressure that we had over here was so low that really wasn't that great. The detector was going off but it just seems like it's leaking down here on the bottom of the actual base plate of the oil pan area. You can see this crap is all over the place as far as the oil is concerned but you also have the pans up here on top which will pull that in and just blow it everywhere. I'm a little leery about pressurizing it with nitrogen because if it would leak through those valves it could go back into the system and there's not a lot of pressure on it to really push up against it so even if I wanted to try to stay underneath my actual standing pressure of the refrigerant it may not be really beneficial anyway. So today right now it's about 49 degrees out here and I am not picking up any leaks so far. Like I said I had already added some oil to it but chances are our pressure on this thing is really stupid low right now. When it was running I checked here on the discharge rotolock didn't pick anything up. So when we was here yesterday I went ahead and scanned the usual culprits around these seals on the filters. I did not pick up anything like I said this pressure sucks they're just it's so cold out here everything's dropped in pressure those are optional that's why we got a cap on that I didn't do that. I walked the building yesterday just to see if we had any catastrophic leaks once they said hey we can wait till tomorrow I said all right let's go ahead and get tomorrow so here we are oh look at that look at that leak that's lovely that thing is leaking that bad with the cap on holy crap yeah that's not good I did not even mess with this yesterday oh that's cute look at that guys let's go ahead and put a cap on there that doesn't have a rubber seal in it brilliant flipping brilliant so yeah look at that big old monster leak we got there so it's leaking through that the place I actually was adding refrigerant was back here on the suction dryer because I wanted to try to let it flash off before it hit the compressor but that's that's just lovely that we are leaking that bad all right got us a brass cap got some new toys here that we're going to be showing off here for long got the trade fox jumper king picked up my own posi lock big 17 the 108 17 ton polar all right let's go ahead and get this cap on how many pounds of refrigerant did we lose because of dumb dumb poor practices they won't be reusing that cap now now see that just makes it even more worrisome to try to trust that that valve there because if it can't even valve off when it's sitting there and they're ready state let's let's just take a look and see if they back seated it or if they were lazy on that too these garbage caps don't usually ever stop anything they're about lucky if they stop the dust well somebody's got that nice and tight because you know refrigerant pressure will never get past the plastic cap of a rubber seal in there now even this being the bigger wrench it won't fit that I have some nice square sockets but you can use a crescent wrench if you want it's fairly tight it does have a packing nut on there let's scan that thing and see if we got any leaks on the packing nut area of course you do kind of ppm route mode we got here okay that's generally what we got is big blue I just used the better spray bottle here okay let's go ahead and soap this thing down I mean obviously it's not bubbling humongous we can try to tighten that packing nut just a touch here we go we'll see how that does now that we've got that let's just go ahead and scan over that compressor see if we got anything leaking out of that area back on super mode I was picking things up along the cracks and crevices of the bottom here I want to scan inside the electrical panel there I've had these leak uh around the terminals where it comes out see if we get anything stupid in here power is off on it I am not picking up anything gotta remember this thing is probably 100 pounds low at minimum so we're not looking for micro bubbles here we're looking for a real dog leak here going back over that now with that there on super mode still nothing not picking up anything here on the brass cap yeah I mean it's it's one of the things okay do we have gasket seals leaking around the top here what exactly is our major malfunction and like I said I did try to clean some of this crap off it just is counterproductive when you got that much grease I mean once again pressures are really low let's go ahead and get this thing warm and running slow pressure switch here set to cut out at about five pounds unfortunately it was very reactive and it was cutting in and out we're gonna be adding refrigerant the whole time so I'm gonna go ahead and bypass that because I don't want to short cycle the compressor to make it a little easier to stay in my area here because I really didn't want to have to fool with that stupid compressor we're just gonna go ahead do it back here yeah let's go ahead and get our hoses blood out and then we'll get started and adding right now what I'm doing is just adding one bottle at a time so we're just gonna go off factory default of what refrigerant is in the bottle we're not even gonna weigh it right now we are on our third jug we're at 240 for our head the fans starting to cycle just about empty on that cyclist it's kind of interesting that they're cycling this fan here in the middle so that's probably jacked up it really should be the closest fan to the manifold here on the end with the leaks that we had sight glass that leaking like a sieve we're gonna go ahead and start searching now that we've got like 200 some pounds of pressure we should be able to find any leaks on the discharge my hose here was leaking a little bit for whatever reason of stupid seals sometimes they don't hold on very good you got tubing all over the place in here and we're just getting all these diaphragms I did take off my low pressure switch jumper there so many places for a leak to happen it's just crazy see how we're doing down here last time we were getting some pretty good size hits down here on the oil fill oh she's shut down she's happy I'd say she probably satisfied unfortunately may have worked out the oil too we're kind of like feeding it pretty quick yeah there we go yeah she she pumped down it's down to 10 psi so now we can at least scan the high side it's got 212 pounds of head on it but the uh low side it's going to be nothing there to set anything off nothing leaking on that suction oh a little bit of there on the suction nothing probably he won't go we're on like I said super mode here yeah I would like to see this completely degreased and all this crap knocked off of it like I said that suction is so low you're not really gonna get anything major off of that compressor that's for your head pressure control so open on uh open on rise and open on differential basically you get a little bit bigger and you've got to basically use two individual valves just because the little bitty ones that you see just aren't big enough what I'm going to do if I'm going to go inside and get the lift because this is a real fandango to get around in here because it's all food area so you got to have your little hair nets and your feet a guy get clean properly and everything's all sanitary so uh I want to make sure we got everything taken care of out here as best as possible what we're going to need to do is open up a solenoid and let some of the refrigerant throw through so that we've got some pressure on that coil like I was saying you know we're only a 13 pound suction you're not going to find a whole lot with that so that's what we're going to do here in a second once I get hold of maintenance let's make sure that uh they know what I'm doing and uh what kind of go from there if I had water and degreaser it probably would be better but for right now we're just going to have to make this work see if we can get some of that oil and crap off there we're going to clean up those edges where that crap's all at just trying to get this crap off the uh compressor top that way we can tell if we have any new leaks or not like I said degreaser would be better but I don't have any on the truck so this is what I'm gonna make work we've got her cleaned up a little bit better I mean it's least not obviously oily okay we're running 240 fans are cycling uh looks like we're a little low on refrigerant depending on whether it's just now feeding or not it looks like our fan control is right there one two three and one two three so something's either out of order or maybe that's how they did it but make sure it's on the right direction appears it is yeah we're nowhere near as much refrigerant as what we need so it's still I think we're pretty much down to vapor at least now we can see whether or not it's any fresh oil leaking from anywhere I mean this thing was saturated with it and now we can see if it's leaking just to make diagnosing it a little bit easier okay it's running let's check our high side here make sure we don't have anything leaking out of that which it does not appear like I said original so you got a little bit down here on the bottom still not sure what you're supposed to do about that so we may have gaskets or something on the bottom that's got issues going underneath this head gasket here picking up stuff on that which is lovely compressor just shut off was earlier when it was low on the refrigerator yeah looks like I got some leaks around the head gasket which would probably explain why you've got such a freaking mess before the compressor I don't know yet we're seeing tighten stuff up so the ppm mode is not always the best mode for finding leaks it's just usually good well it'd been nice to not have that just kick right on but literally down here on that crack where the plates are together we were getting up to about 40 to 50 parts per million and it really is nothing else that would be causing that I was thinking about seeing if I can get the torque rating and double check and see these I think this serial number's a 2020 and it's very possible that we probably had COVID employees doing it which means it's probably done incorrectly all right so I wrote filter dryer cans were rated for 20 to 5 to 30 psi this is a cheap Pittsburgh but I'll tell you what at least it's going to be consistently the same torque on every bolt so I set it up for 35 well guess what I'm finding out it's turning on pretty much all of them so we've been going through and I'm tightening each one up till it finally locks up most of these I've gotten quite a bit of turn on and these here I've already gotten but I got to get in there a little bit further to get those back once we'll recheck it after we get done yeah right here's one there so yeah it's been like that so we're gonna go ahead and do the whole thing chances are it was probably put together improperly this everyone's saying that it's probably a year old maybe two years old at the most and it wouldn't surprise me so we're gonna go through and torque everything we'll see if it works it's probably crap in the gasket now probably too late but we can put new head gaskets on it now the bottom piece uh I'm sure it can be done uh but that definitely would require us to yank it out flip it upside down and probably uh redo that Copeland's real close to my area a good portion of these have turned some are fixed a little bit of a turn keep on shipping them jobs out that's what you get not saying americans do a good job all the time anyway because half of them are drug addicts or lazy or whatever gosh look at all that now this dumb thing didn't just loosen up they either didn't torque it and that's at 35 hopefully that's the correct torque I mean if it's good enough for a filter I gotta hold it trevor rath used to ask him since he worked for cope one emerson whoever you want to call him that week and see if he had any any answers for me if he knew what the uh correct torque was I don't think it sucks I don't think I can get on this bottom very easy but yeah I might be able to get on that claw foot possibly I'm gonna do what I can on the bottom we'll see what we can do here see what we get here still getting a little something but nothing like we had earlier my bill taker up to 40 I really wish I knew what the foot pounds were on that I don't want to go too much see if we get anything down here on the bottom now I'm not really getting anything I am just a touch but like I said I went through and wiped all grease off of that wow we're not hardly getting nothing so it might all be back here I was getting stuff yeah see still am yeah see that I got some major leakage on the bottom there I can get to those luckily underneath here wow now we're leaking it those not not those bolts what a joke piss poor quality we're doing a little web search all right so looking at this emerson bulletin cylinder head head bolts capacity control blah blah blah they are grade eights they're doing an inch pound so depending on what it is there's 300s 500s those are 40s three whatever's let's see what this thing is I don't remember maybe we can see it on this other compressor tag because I don't know if that took some of the tag off or not okay this is maybe a 3r something a discus I can't read it because the stupid thing came off let's just say 300 inch pounds well there's 12 inches in a foot so at 300 divided by 12 be 25 go figure right at 500 divided by 12 would be 41 so I was doing 35 I guess we're just going to stick with 35 we'll see how that does if it holds great at this point you know I don't yeah what do you know what do you know I don't know nothing so let's get down there see if we can tighten them up all right this is going to sound kind of chintzy but we took her down to high which is what half the detectors out there can do and when we check the head gasket there does not go off but if I go down here to the bottom it was kind of hitting every now and again on that the bottom plate all of the bolts were tight we're not loose at all they're back to super which you know the super is kind of for sniffing things out it's very stupid sensitive when you do that see how we got we're getting hits there that's how I find leaks that everybody else misses going to high which is what the old D tech had nothing so I always go on super just because I try to find everything but I'll tell you from what I'm seeing we just made it a hundred times better than what it was I mean a pound here or two there I'm not horribly worried about but a hundred and that could be a problem what we'll do as always I put it in their ballpark we will say hey flicking along the bottom a little bit and if you want to fix that we can for you but here we are back on super just kind of scan the top of the head gasket the bolts had to get a deep well for this one there where they mount the pressure switch not really picking up anything now I got that cover back on the electrical I'm going to go inside and scan the evaporators but you can tell this has been going on for a while that crap that's all over is just ridiculous yep 56% crazy it's been lasting that long it is just crazy I got everything cleaned up it still not came on it went through a defrost thought we'd be eventually getting to it so I'm gonna do so I'm going to go ahead and relieve that let that go there it goes get too far down and don't release so you gotta get me right in the middle there it's kind of corny as soon as this thing comes on like that I'm gonna go ahead and kill it that'll let the fresher continue to build up a little bit I don't want to let run for too long because I don't want too much liquid coming back it's right now boiling off through the evaporator so I just wanted to make sure we had enough pressure on there to pick up any leaks if there is any inside so let's go ahead and undo that and we'll put this back on that way we don't forget and accidentally burn the coil up and let's go inside and see if we can find anything all right so those lines come in right there in the wall and they come up and it looks like it's the back one right here so they go across and they go to those evaporators right there all right let's go ahead and kill these so we've got four monster fans here we're gonna let that stabilize for a sec obviously it's turned off we're gonna see if we can pick up anything coasting out again remember we put up pretty much close to 100 pounds in this thing so if it was leaking in here it should go berserker what I wanted to do was check the distributor tubes and inside this the evaporator box that's been running so it's going to suck all the refrigerant out and blowing it out but like I said if it was really hammering down and leaking you would have it going off luckily we got the lift here that makes it a lot easier so we've got this opened up and we're going through and we're pretty well sniffing all these areas in here just to make sure everything's clean and clear which I already went through it but just to kind of document it I'm going ahead and getting it on here I went ahead and went through each individual piece there didn't see anything at all and we're going to go ahead and scan the back of the coil real quick can get inside here too like I said we should be picking things up if it's that big of a leak we've got that one back on got this one off then scan this over and then if there's no leaks we'll be done well that's kind of interesting strap holding that bad boy up that's pretty creative suppose whatever works okay so we've got this one opened up we went ahead and scanned all up inside there surprisingly no leaks in there either scan the back side of the coil so good to go all right so while we're here let's see if we can get this thing running then be able to wrap it up so I think this might have got damaged it's a variable speed for a exhaust that is up there all right guys it's going to wrap that one up as you've seen there we had leaks all over the place and we got them all fixed there's itty bitty bitty bitty bit I don't know the one on the very bottom like I said it's super super super small I think the cost to try to get that fixed probably is going to outweigh any benefits of trying to repair it I guess we'll just go at this point what we're going to do is just watch it and make sure that it's not becoming an issue we've went ahead and checked all the other areas to see whether or not there's any other areas leaking and at this point I believe we're good to go so if you guys
