Hi from Thailand - retired Australian engineer this end. Mostly Optic fibre design, but a LOT of work for A/C for data centres... LOVE your work, never stop learning, MANY THANKS!
First thing I suspected was a leaking suction service valve. When you front seated the discharge service valve, and the bypass leak went away, that proved the gas was coming from the high side. Many times we don’t have both sides like that. Ya gotta love the semi’s.
Brilliant video mate! Was well worth the wait! I’m a junior engineer , but most of the systems I work on are semi hermetic compressors in glycol chillers. So it’s good to see this kind of stuff 👍🏻👍🏻👍🏻
AWESOME video on the gasket and reed in the can. Used to do those alot. Usually gasket leeks before reeds breaks but each can is different. Thank you for the video very helpful to see it. I would like to see you do a NAVAC cordless vac pump. I think it would benefit many. Stafe safe kid.
Great video. You won't get static from the office about not changing the compressor will you? My old boss ripped me apart for do the same thing, but as I said, he's an old former boss. Great video.
No , I had to send in my work order from the first call telling the office we needed to do valve plates first. They quoted and ordered and they came in today and I did them.
The true sign of a seasoned tech: That little piece of plastic from the broken suction gauge cover just floating around in there. Lol if it ain’t there, double check their work…
Bloody good video brother , thoroughly enjoyed it mate 👍 By the way , is there anywhere you can find information about the torque setting on the bolts , if you wanna get fancy ? I tried finding if for the filter dryer cartridges but I couldn't find anything , so I just go by what I feel is right , then I just break out the torque wrench just to make sure each bolt is evenly tightened ... Well , assuming my torque wrench is well calibrated and precise enough that is ...
@@Cscrefandhvac No, the pins which hold the new reed valves. You mentioned it around 7:00 mark. Did you get any video of changing those pins? I've been told for such simple pins, if those break the compressor is pretty much gone.
@@torosfcp yes , those were fine and not broken. Old ones pulled right out so I could put in the new ones. But yes if those break they will be in the comp somewhere and that’s no good ahhaha
Thanks for the reply , yes I have done a million and one rebuild jobs on all kinds and sizes of compressors over many year here on Trinidad island in the Caribbean .
I know I know hahaha. I call the suction one a king valve a lot . Also I just film these once while I’m working . I make mistakes with what I say plenty of times but I’m not gonna back and retake a vid , gotta get the job done and running
Too Right brother. What year was that compressor? I collect data tags of dead semi herms. They're like the semi truck of the refrigeration industry. Tin cans are not practically recyclable/serviceable
I got fooled by a liquid to suction heat exchanger recently. Blamed the solenoid valve (Alco junk). Replaced it, wouldn't pump down, but compressor isolation proved it was good. Turns out... The liquid to suction heat exchanger had an internal leak... I was so pissed but happy to realize my mistake. Uncommon failure in my area SWFL
@@jakem117 for sure man. A lot of those liquid to suction heat exchangers are gone now haha. They are useless , took me a long time when I was younger to understand how it worked and what it was for

Hey thanks for watching , I appreciate that .
Hopefully it’s possible to do a video on the symptoms of a solenoid valve that’s leaking by and how to diagnose that.
Good Job on that valve plate . Those semi hermétics are fun 😊

Every compressor should have service valves in them in my opinion
@@Cscrefandhvac I agree! hard to do service, without service valves.

The Navac review would be great. Nice job diagnosing it.stay safe.
Very informative, dont get to see this everyday! Thanks
Great job man! This really hepled me out when I saw pressure rising after pump down in the field! Keep up the great work!
Great explanation of how the valves work 👍👍
Thanks for showing the repair!! I've done some of the larger 3d and 4d also the 06d from Carrier... Done some valve plate and flapper swaps also!!
Great job bud. You taught me a lot back in the day.
Thanks brotha ! Miss ya man 👍🍺

Thanks Ray you too bro
@@Cscrefandhvac Thank you brother. You are always welcome.
We learn a lot from you. Thank you..
Where can you buy this parts ?
very professional
Great to see ya , stay safe brother
Great video.

Great vid 👌. Welcome back
Great Example👍
Great video. Don't see that too often
good job 👍
Great video, keep up the good work 👍👌
Nice job, Brother.
Thanks bro
thanks for the video and knowledge
Thanks
Another great video bud👍👍
Great video! Keep up the good work!
Good video man
Do a video on vac pump!
Join the havcr overtime show bro!
I enjoy your videos brother i work the produce market place in hunts point ny the bronx
Nice man. I’m always in the Boston one haha
Nice work!

Great job 👍🏻👍🏻 👍🏻👍🏻
Will it pump down if the unloading valve is open on a compressor with an unloader?
thanks for the videos!
Nice Job
Do you need to torque down the bolts and in a certain pattern.
Yes you go in a star pattern to tighten them
Bloody good video brother , thoroughly enjoyed it mate 👍
By the way , is there anywhere you can find information about the torque setting on the bolts , if you wanna get fancy ?

I think you can find the torque settings on copelands website somewhere.
Could this be caused by an issue with superheat?
Liquid slugging caused this failure?
Good one 👍brother
Thanks brotha
Blessings
Thanks
Nice video!! How did you change the dowell pins? I've been told they're a nightmare to do. I'd like to see how it's done.
Are you talking about the pins that line the valve plates and the head up correctly ?
@@Cscrefandhvac No, the pins which hold the new reed valves. You mentioned it around 7:00 mark. Did you get any video of changing those pins? I've been told for such simple pins, if those break the compressor is pretty much gone.
@@torosfcp yes , those were fine and not broken. Old ones pulled right out so I could put in the new ones. But yes if those break they will be in the comp somewhere and that’s no good ahhaha
Carlyle actually recommends not to change those pins unless there’s an issue with them
Flooding back to break the reeds on the 3d
Yes it was
👍👍👍
Why compressor stop when reached to 70 psi after closing the pressure valve?
I don’t understand your question ?
Well diagnosed it is val plate leakage
How you drop the pressure on the compressor
Not sure what you mean
@@Cscrefandhvac sorry I got it
It looks like the compressor was re- built before or factory refurbish because it has 20 thou over size pistons in it .
It very well could have been but I am not sure
Thanks for the reply , yes I have done a million and one rebuild jobs on all kinds and sizes of compressors over many year here on Trinidad island in the Caribbean .
Excellent video. One pointer, that's not a "King Valve" those are on the outlets of receivers. That's a suction service valve :)
I know I know hahaha. I call the suction one a king valve a lot . Also I just film these once while I’m working . I make mistakes with what I say plenty of times but I’m not gonna back and retake a vid , gotta get the job done and running
Too Right brother. What year was that compressor?
I collect data tags of dead semi herms. They're like the semi truck of the refrigeration industry. Tin cans are not practically recyclable/serviceable
Oh man. I don’t have the data tag pic anymore. This comp was from the 80’s - early 90’s at least . Systems have been at this site forever

Woow, a vacuümpomp on battery??
Yes the Navac 2cfm
Great video.
