@@HVACRVIDEOS all above i agree with... also... don't lose your sense of humor either!... the intro to this video had me splitting my sides... had to rewatch it twice to allow the captions show what you said.
Well spoken for sure. Spot on just think if we reinvent the wheel we have a HIGHER CHANCE of mistakes to over come. And who wants more mistakes then what we all ready have. Chris spot on again young man you impress me everytime. Great video. And most of all thank you for your time,effort, and your knowledge of this trade. Love it.
I bet they forgot to add thread locking compound to those bolts. As soon as they begin to loosen, even slightly, the vibrations will increase, which will feed back into the bolts causing them to loosen even more, perpetuating and accelerating the problem. Consistent vibrations will almost always loosen nuts/bolts unless you use special metallurgy/glue/torques/etc. Once vibrations start then just about all other problems follow. Vibrating parts are rubbing, causing friction and heat, which will destroy the oil causing even more issues. Other bolts loosen, metal fatigues and cracks, and so on. Edit: Really like your videos. Enjoy seeing into the black hole of HVACR
My family is in the HVAC industry, but I teach architectural drafting. The default roof access for many designer is a 24”x24” roof hatch and a ladder. I’ve had to climb up through these, and can’t imagine doing every day and hauling tools and equipment through it. On a 1 storey building with a short parapet wall, that may be okay, since you can likely pull stuff up over the parapet rather than having to haul it inside and up through a hatch. On buildings 2-10 storeys I have my students use a ship ladder at the top of the staircase with a larger 36”x60” hatch that makes roof access easier. On taller buildings, we’d have a full staircase to the roof - sometimes even one elevator. It’s not all about designing buildings to look good, but also makes them easy to service so they can continue to operate for years. Love the videos and your dedication to your trade.
Thanks so much for watching, funny I took 4 years of Architectural drafting in high school. I thought I wanted to go to school for that and become an architect but I changed my mind after my senior year. anyways thanks so much for the nice words!!
17:58 I really like how you explained how the charging chart works. I don’t think I’ve seen that before in your other videos. It’s funny because I’m a volunteer fire fighter and so whenever I’m at the fire station I like to go up on the roof and look at the equipment just to see up close in person some of the stuff that you’re talking about. I don’t remember seeing those charts on our package units so I will have to look next time I’m on the roof. You’re so damn thorough I love it. I’m sure most people would not have installed the uni-strut to support the lines the way you did. It’s funny how you do things differently (properly) when running your own company. I’m the same way with my company. Super clean job, well done!
Just so you’re aware, those charts are only present on Carrier units I believe. So if you have a different brand of roof top units, there may not be a chart like that. I know some Lennox units have a chart as well inside of the electrical/compressor section. Enjoy looking at the units!
Don’t look too closely. I did the same thing following HVACR videos and yearning for more real life examples. Visited a few RTU’s in some of the exchange buildings I work in. found all sorts of dead units, error codes clogged condenser coils etc. Now I’m on a first name basis with our HVAC repair contractor lol. I only wish we had a tech as detailed oriented as Chris!
20:53, Hannibal Lecter LOL. It’s totally cool being able to see all of the internals. It’s always smart to try to take things apart and find the point of failure. This is how we learn
I really enjoy your videos. I don’t work in the industry, my dad did I his whole life. He passed in 1983. I used to go to work with him on the weekends and during the summer breaks from school. My first job was working for a family friend building air conditioning control panels. I really enjoyed that. I really enjoyed working with my dad and the other techs on weekends. He was a designer later in life, but the techs let me work with them and it was fun. Back then the hot control systems were made by Staefa. I ended up going into the telecommunications industry but I like watching these and being reminded of the old days. A lot has changed and it’s cool seeing the new tech. I’m still pretty good at controls and electrical on residential systems and I help out friends when I can with thermostat and capacitor swaps. Keep making them and I’ll keep watching! It’s always nice to get a notice when you have something new posted. Be safe!
@4:25 You can see torch smoke flowing out from that valve--forced by the purge gas. @10:54 to @15:10 if you want feedback: I might hit fast forward when you make six (!) perfect, identical brazing joints* in a row. As in: show the start of one, then speed it up a little. *I was VERY impressed with those.
For the pulley system you might want to look at adding a Prusik loop. That would allow you to let go of the rope and not have everything fall down. They are easy to make in the field or you can buy them ready made.
Nice work as always. Like how you take the extra time to figure shit out & not just knock the job out. Great way of thinking, keeps call backs & repeated failures down. I'm 54 & been in the trade 26 years, & my back feels like it too. Keep working smart it pays off in the long run.
This compressor was damaged by overheating...and then cooling.. The expansion and contraction was enough to pull those bolts out slowly...also the force of that stator vibrating will destroy anything eventually. Also could be from the manufacturers doing a shotty job building the compressor. But im going with the expansion theory tho
Don't forget that the screwholes are chewed out sideways. It could have been the rotor all along but expansion is part of it as you said. If you overheat it, it's possible that the bearings were pressed axially by the rotor, they held up, then the rotor bent a tiny bit, bowing to the side from the pressure, giving it a bit of excentricity and angle. Now you are twisting the bearings around in their socket. If the screws chewed the bearing holder even just a tiny bit, this became a self fueling circle where the excentricity got worse and the screws rattled more and more. This is just an idea but this is an issue I ran into when trying to make a bearing holder once and it acted just like this. non-parallel bearings are absolute monsters
Along time ago when I had a summer job installing TV antennas the foreman told me something I have never forgotten. Whatever needs to be at the other end of a ladder should be set near the ladder. If you are going up or down, grab whatever is waiting, there will always be something waiting.
Very interesting,you rarely get to see what killed a compressor because no one ever bothers to take them apart . The gantry was nice . They really should have some kind of lift on all those hatches . It is a smart innovation.
You are the man I learn a lot of stuff every time I watch your videos. Keep up the good work I appreciate everything you teach me and the rest of the world
A small tip to make your lift a bit safer: you should install a safety that prevents the weight from going back down if you slip or can't hold it anymore. There are some easy ways to do it and it safes a lot of money if something happens
I’ve enjoyed the videos. I used to work in a factory assembling these Emerson Scroll Compressors. (Well more than ten years ago. ) The bushing on top should not be oblong that slides into the rotor shaft. All bolts are installed using computer controlled machines that check for proper torque and I think the bolts have thread locker pre applied. My guess (for what it’s worth) it just wasn’t perfectly balanced and started to vibrate causing the excess wear and eventually the two main failures you noted. Was fun to see the insides of one again!
I Commend you for removing the old compressor instead of leaving it out of sight meaning on the roof out of sight of customer many techs would leave a compressor on the roof because they R 2 LAZY to clean up after themselves
Years ago I had a bad reversing valve and when removing the line between the compressor and valve it had pressure trapped in it and blow apart when i put my torch on it and it put hot oil all over me, I was wearing my PPE and long sleeves but still received some burns on my face So now I always take my awl and punch a small hole in all four lines. Please all take note really enjoy your videos Stay safe
@@Davemte34108 The trapped pressure in the line was a fluke and only happened once, But with that said this is for the young up coming techs. I retired after 40+ years in the trade. Still involved with local apprentice programs. Stay safe
Wow, thanks! I am going live on TH-cam this evening 10/12/20 @ 5:PM (pacific) to discuss my most recent upload and answer live questions from emails, TH-cam comment and the live chat, come on over and check it out. th-cam.com/video/FNJac28OvjU/w-d-xo.html
Put in foam ear buds when it's loud. After a couple minutes you should be hearing almost normally and still hear vibrations or if something is rubbing.
Solenoid valve? I believe Carrier requires one for long lines. It could be liquid flood back washing the oil off of the bearings caused the failure. Common problem in malls.
Am 43 now chris and my back is killing me and my knees are knocking because I was at a mind set of just doing things to get the jobs done in my earlier years, man if I could turn the clock back I would do a load of things differently now !! Now my body come first!! Take care buddy 👍👍
24:13 Drive adaptor bushing Failure, is what happened to it, The Bushing in the adapter failed, allowing the shaft to slightly rotate, More than it should have, allowing the compressor to vibrate, which Caused the screws to vibrate out, what cause it could be anything, Manufacture defect, bad oil, Reversing valve Surg, Contaminant, ect.
16:28 I thought you were going down that roof hatch for a minute, that scared me. I know it wasn’t even close and you know what you’re doing but it made me nervous!
Put light pressure on the line while I torch it. You might want to move your hand out of the flame. Actually the way the guy was pulling on the lines at first it was like his first day on the job. But a few solder joints later he was a pro. Maybe he just hadn't had his coffee yet.
Gordon Freeman has a good point. I'd also like to suggest the possibility of a slightly off-balance motor. If that top part was weak from the factory and failed, that would cause the motor to flop around a bit, which would wrench on those lower bolts until their mountings failed. impressive that the bolts themselves held up so good, considering the damage to the mounting plate on the bearing.
Good afternoon. I work with these refrigeration equipment and I have disassembled these Copeland Scroll compressors and it is not the first time that the lower rotor bushing is loosened by these two screws and causes damage to the equipment due to friction or overheating.
I could never thing or dream or whatever that i would be watching this kind of content. Im quite interested in tech and im keen on learning all sort of stuff and repair all devices in my house and friends houses beside graduating law school and working in that field for over 7 years now. Just wanted to say that you man have an amazing channel! Its a pleasure watching your vids and your approach to work. I dont like every word you say but thats maybe just my law side :) cheers and keep up!
I love watching your videos sir, seeing how you accurately and safely diagnose issues, and have all the proper equipment for every job makes me want to change company’s knowing how mediocre my refrigeration company can be.
I was going to say the same thing. An old journeyman showed me that many years ago. Much easier change out. This one wasn't too bad with the couplings.
Idk if you get paid more through commercials or through premium members but as much as I hate supporting youtube I can never go back to a non premium member!! Love not seeing a bunch of ads. Some channels theres ad after ad after ad. I like seeing the video straight through.
Yeah I have premium too and I still get paid with premium, I will discuss this on my Livestream this evening 10/12/20 @ 5:PM (pacific) come on over and check it out. th-cam.com/video/FNJac28OvjU/w-d-xo.html
Love watching your videos. I am a Dual ticketed journeyman in gas and refrigeration. After 8 years in commercial refrigeration, I was laid off due to this pandemic. I found a job with a residential company so watching your videos keeps my knowledge up. Thanks for the content
My heart skipped a beat at 16:28. Thought for a moment you were about to take a very unpleasant tumble. Love the teardown. I wonder if perhaps the bearing had too much friction for some reason and it eventually loosened the bolts from starting and stopping. That or maybe they weren't torqued or loctited right from the factory. Weird failure indeed, Great video
I higly recommand to check the oil on a short notice. It is most likely very dirty due to mixing with the old oil. So an oil-change is required. Nice job.
I need to give that putty a try. Great video, as always. A tip. Rent a two man scissor lift or a boom lift to get all equipment to roof. Obviously it will add a cost to the job but the time saved in hauling everything to the roof more than makes up for it.
I clearly need to get some of those special heat protection rags. There's some stuff I want to get, but I'm not ready yet, so I hope the arrangement with Tru Tech Tools goes on for a bit...
I won't bust your chops on your rig. I'm still roping every thing up by hand. You got the job done and your customer was happy. So win win. I'll never forget a helper who told me a half ton semi-hermeric Copeland compressor was to heavy to lift by rope. So I had to tie off the compressor and lift it up to the roof myself, and drop the old one down. I was told my attitude was reckless. I tried to explain we have a job to do and there ain't going to be a crane for a half ton compressor. I told him he was lazy and could leave any time. An old crick in my back says that scroll compressor is a whole lot heavier than a half ton Copeland compressor, and a lift rig may have prevented that crick in my back. So like I said, I'll not bust your chops for working smart. Great video. Good job, and may all your helpers be helpful😂
I would not flare the drier either. On 1/2” a flare torque is roughly 40 foot lbs. and like you said other people could could unintentionally mess things up. Good work. I like the pulley set up to.
3:39 that’s what she said LOL, 4:59 that’s what she said LOL, 5:31 that’s what she said LOL, 5:48 that’s what she said LOL and finally the mother of all that’s what she saids, 8:43 that’s what she said LOL i’m just having fun man don’t block me. I love your videos! I find them very informative. I just like watching somebody run their own business as I have my own business as well.
When brazing/soldering and the filler metal suddenly decides to make the move into the connection, it is somehow very satisfying to me. Don't know why. Just sort of a "Got it!" moment. Looks like you make good, solid, well-filled and smooth joints.
@2:00, should have had the winch rack pushed to 1 side or the other, not in the middle, as then when the compressor was up, you could roll it to the post and have room for it to land. A brake or some other strap to also hold it would mean you don't need to keep pulling on the rope just to hold it in place... so it doesn't fall. Same at 16:30. Having your hoisting rig in the right spot makes it easier to raise/lower equipment.
Hi....I never dessoldering to remove any parts ... Because it can blow oil firer on my face I always cut the pipes.. You doing a good Job..from Portugal ...be safe ... take care!
Good job. I am in my mid 50's now and still try to rope up comoressors. I like your gantry crane and have been looking to build something like that for a while now. Thanks for posting!
You should have cut open the old compressor first to check how much oil was in it instead of checking the receiver! You would have saved alot of work and time! Always remember this : work the job! Don't let the job work you! I agree with you about flare nuts you want as few as possible because I have found they are leaking points in the future because they loosen as the metal expands and contracts! Did not see you leak check you solder joints? There is no easy way to get the compressor onto the roof even getting a sign crane creates time and money issues! If we had stairs to the roof we would fasten a pipe to the compressor and 2 of us would carry it up to the roof and vice versa! It saves alot of time bringing up and setting up a lift device! Liked how you made a support for the drier! That was alot of work it was smart to have a helper there with you! On a big job it's easy to over work yourself and get hurt trying to do to much! Even at your young age remember that you are not getting any younger and when you get older what you do now will definitely determine your physical health as you get older! As so many young people do you can't just live for today you have to think about the future! It will be here sooner than you think! You want be able one day to retire and be able to walk away with out a cane or Walkerand be able to enjoy yourself in retirement! The answer to that starts with what you are doing right now! Thanks for another awesome video! I enjoyed it!

I bet they forgot to add thread locking compound to those bolts. As soon as they begin to loosen, even slightly, the vibrations will increase, which will feed back into the bolts causing them to loosen even more, perpetuating and accelerating the problem. Consistent vibrations will almost always loosen nuts/bolts unless you use special metallurgy/glue/torques/etc. Once vibrations start then just about all other problems follow. Vibrating parts are rubbing, causing friction and heat, which will destroy the oil causing even more issues. Other bolts loosen, metal fatigues and cracks, and so on.
Edit: Really like your videos. Enjoy seeing into the black hole of HVACR
Really looks like somebody on the assembly line messed up the torque or did not put threadlocker on the threads
Yes u are rite
I agree - looks like a manufacturing defect to me. A third alternative would be that the bolts weren't properly hardened, which sometimes happens.

You should do a behind the scenes video of your job site videos - how you set up the shots, outtakes etc. it’s really an art form how you do it.
Great set up, and info. Chris. Great job.
Love watching your videos. I am a Dual ticketed journeyman in gas and refrigeration. After 8 years in commercial refrigeration, I was laid off due to this pandemic. I found a job with a residential company so watching your videos keeps my knowledge up. Thanks for the content
Check in to General Parts we are hiring everywhere before, during and after this pandemic
@@dmiestercommkitchentech3043 thanks but not in my area. I live in Canada
My heart skipped a beat at 16:28. Thought for a moment you were about to take a very unpleasant tumble.
Love the teardown. I wonder if perhaps the bearing had too much friction for some reason and it eventually loosened the bolts from starting and stopping. That or maybe they weren't torqued or loctited right from the factory. Weird failure indeed, Great video
I always used a chain hoist. Safest way to move anything.
Stay safe and healthy! Nice video as always!
Bad day at the factory. And look what had to be done to fix. 👍
I higly recommand to check the oil on a short notice. It is most likely very dirty due to mixing with the old oil. So an oil-change is required.
Nice job.
I need to give that putty a try. Great video, as always.
A tip.
Rent a two man scissor lift or a boom lift to get all equipment to roof.
Obviously it will add a cost to the job but the time saved in hauling everything to the roof more than makes up for it.
I clearly need to get some of those special heat protection rags.
There's some stuff I want to get, but I'm not ready yet, so I hope the arrangement with Tru Tech Tools goes on for a bit...
GREAT VIDEO, THANKS
i always get excited when there's a compressor autopsy.
I won't bust your chops on your rig. I'm still roping every thing up by hand. You got the job done and your customer was happy. So win win.
I'll never forget a helper who told me a half ton semi-hermeric Copeland compressor was to heavy to lift by rope. So I had to tie off the compressor and lift it up to the roof myself, and drop the old one down. I was told my attitude was reckless. I tried to explain we have a job to do and there ain't going to be a crane for a half ton compressor. I told him he was lazy and could leave any time.
An old crick in my back says that scroll compressor is a whole lot heavier than a half ton Copeland compressor, and a lift rig may have prevented that crick in my back. So like I said, I'll not bust your chops for working smart.
Great video. Good job, and may all your helpers be helpful😂
I will discuss this on my Livestream this evening 10/12/20 @ 5:PM (pacific) come on over and check it out. th-cam.com/video/FNJac28OvjU/w-d-xo.html
Loving your videos keep up the good work. From a colleague hvac technician from Belgium
Excellent work and thanks for the awesome content stay safe and take care
Nice videos cutting does compressor opening and detailing the problem just a mechanical problem looks like! 👍👍👍
I would not flare the drier either. On 1/2” a flare torque is roughly 40 foot lbs. and like you said other people could could unintentionally mess things up. Good work. I like the pulley set up to.
Thank u for the video it was awesome!!👍🏼🙏🏼
Hey! Where are the nasty food prep chiller repairs??? I need my fix, I'm starting to eat at restaurants again!
Definitely would be interested in some stickers and a shirt re design 👍🏻
I was surprised you didn't catch fire when learning over to braze the joints at 13:20 ish lol
Man! You do a great job.Love watching your videos.keep them coming
Enjoying the window view of outside.
3:39 that’s what she said LOL, 4:59 that’s what she said LOL, 5:31 that’s what she said LOL, 5:48 that’s what she said LOL and finally the mother of all that’s what she saids, 8:43 that’s what she said LOL i’m just having fun man don’t block me. I love your videos! I find them very informative. I just like watching somebody run their own business as I have my own business as well.
ohh, compressor autopsy, my favorite. lol I like to see how things failed and try to determine what caused it.
Awesome videos Chris keep them rolling!
Another fascinating tear-down of normally invisible machinery. Thanks, Chris!
"Invisible machinery" sounds like a good TV show name. :p
When brazing/soldering and the filler metal suddenly decides to make the move into the connection, it is somehow very satisfying to me. Don't know why. Just sort of a "Got it!" moment.
Looks like you make good, solid, well-filled and smooth joints.
They used their calibrated torque wrist to tighten the bolts..
I have a couple of those. They are great, I can adjust the torque setting just by thinking by thinking how tight I want the fastener to be.
0:58 the compressors good it just needs some P.O.E oil lol good video Chris I love that lift you made with unistruts 👍👌
Always learn something new😁
Great job and video like always
I just had my brazing final in class, what a coincidence you braze a whole bunch in this video 😂 glad to know it’s used a lot
@2:00, should have had the winch rack pushed to 1 side or the other, not in the middle, as then when the compressor was up, you could roll it to the post and have room for it to land. A brake or some other strap to also hold it would mean you don't need to keep pulling on the rope just to hold it in place... so it doesn't fall.
Same at 16:30. Having your hoisting rig in the right spot makes it easier to raise/lower equipment.
No nitrogen used while doing 500 welds, no pressure test.
Uses a bigger dryer.
My man 🤜
Hi....I never dessoldering to remove any parts ... Because it can blow oil firer on my face I always cut the pipes..
You doing a good Job..from Portugal ...be safe ... take care!

Good job. I am in my mid 50's now and still try to rope up comoressors. I like your gantry crane and have been looking to build something like that for a while now. Thanks for posting!
Me too, but nothing over 5 ton any more, Mikey.
Good work bro!!
For the first time I am early and also I enjoy your videos not only because I find it cool but you give a lot of information that is teachable.
Love these videos !
Excellent job 👍👍👍
Couple of times where you needed a roach clip for your solder. Haha. Great video Chris.
Thanks buddy 👍🙏🙏🙏🙏
Im loving the compressor tear downs
You should have cut open the old compressor first to check how much oil was in it instead of checking the receiver! You would have saved alot of work and time! Always remember this : work the job! Don't let the job work you! I agree with you about flare nuts you want as few as possible because I have found they are leaking points in the future because they loosen as the metal expands and contracts! Did not see you leak check you solder joints? There is no easy way to get the compressor onto the roof even getting a sign crane creates time and money issues! If we had stairs to the roof we would fasten a pipe to the compressor and 2 of us would carry it up to the roof and vice versa! It saves alot of time bringing up and setting up a lift device! Liked how you made a support for the drier! That was alot of work it was smart to have a helper there with you! On a big job it's easy to over work yourself and get hurt trying to do to much! Even at your young age remember that you are not getting any younger and when you get older what you do now will definitely determine your physical health as you get older! As so many young people do you can't just live for today you have to think about the future! It will be here sooner than you think! You want be able one day to retire and be able to walk away with out a cane or Walkerand be able to enjoy yourself in retirement! The answer to that starts with what you are doing right now! Thanks for another awesome video! I enjoyed it!

I love the backpacks for these kind of job's. So convenient.
I like your sporlan catch all filter drier too even when i am in philippines i used that kind of filter drier for a long time
