Copeland compressor teardown 

Your laid back personality and the way your honest with being unsure and admit it ur professionalism is great

Never had one apart like that. Thanks for taking the time. Surprised that Copeland didn't want it back.

Hi Bill, That was fun to watch. And it got very funny after you said: I don't have the right tool Can't see too well but I am sure I noticed a bit of a pinkish coating on the inner surfaces? Especially the crankshaft journals? That's what you see if the system has been running acidic, for whatever reason. That's copper been dissolved from the tubing in the system and plated onto the steel surfaces. That usually invalidates the warranty on a compressor, if that is found. It means anything from moisture to high discharge temperatures. I like the diagnosis of a nice slug of liquid having been ingested, one will never know at which part of the cycle it happened, if the oil was hot or cold and so on. To get the stator winding's out they pull hard on them and heat the casing with some big propane gas flames, the casing expands and the stator pops out. The oil pump is trochoidal, and if you look at them you can see the outer ring can rotate. That automatically lines up the suction and discharge ports of the oil pump with the galleries in the compressor so that it pumps the right way regardless of motor direction. It is recommended to not change the motor direction on a compressor that has been in service though, as the ring does over time bed itself into position and may fail to rotate if the compressor is spun the other way. That would lead to no oil pressure. Yea, I could carry on all day about this lol. I love any kind of rotating machinery. Thanks for the great video, appreciate you sharing it. Kind regards from South Africa. Duncan

There are so many of those in my area, still in service. Thanks for showing the teardown!

oil pump at 6 mins is a fairly standard design for automotive. bulletproof reliable, likely one in your engine and power steering pump.

I found this to be rather humorous..! Back in the day ( 30 ) years ago industrial transportation freezer Copelands used these things called unloaders to control capacity in conjunction with temperature control and if one of them had a problem the compressor would only cool to a certain temp and stop cooling. I had a new guy with me and told him to check it out and see what he could find, I already knew it was one of the unloader solenoids. I came running back when I could hear the compressor slugging from the next room over. To late, he was dumping liquid right in the suction valve and screaming it was a low charge...! Welp when I took it apart it looked like yours except the valves were shattered also..! Needless to say the new guy didnt work out....

I love the tear downs you do keep it up!

Hell yeah I’ve been looking forward to this video. Don’t let Chris Stephens see you using that impact. 😂

Totally the best way to learn....

WOOT! i'm excited for this one :) they had lots of these at school but alas I wasn't in HVAC class so I didn't get to check them out closely, aside from the one my buddy found half buried behind his barn LOL.

Thank you Bill. Good teardown 👍

Did refrigeration and AC for forty years, replaced many coplematics with a AC can semi hermetic, one forth the price, when all ya got is refrigeration supply house 500 miles away and ya got a down walk-in frig freezer you do what ever you can, seen them running five years latter, no problem...

Thank you. I have 2 going to try and make one.

Thanks Bill, enjoyed this one 👍🏼

I don't think I've ever seen that particular style of compressor in the field. The only time ive seen one similar was back when I was training to become an Engineer.

chrome socket on the impact is crazy. is that a 2D?

The oil pump is called a g rotor pump in the car biz. Widely used for engines and transmissions.

Good FM radio voice on this feller

Looks like you need a bigger impact for the connecting rod bolts.. :-) Thanks for the video.

Oil pickup with strainer. Usually the best place to start a teardown.

Nice👍

question what is happening when u add power and the motor just lock up but it can turn fully when de-energized

I have one of this that keep tripping the breaker a couple time but it runs i have 0.82ohms at the windings,do you think this one is bad?

Cracked connecting rod? Probably flood back. Could be lack of pump down during defrost or off cycle, but either way, hydrostatic pressure is crazy lol

I rebuilt many semi- hermetic compressors, the motor winding leads that connect to the terminal block, they do not have to be put back on in any specific order. all it will do is make the compressor run in reverse rotation. the oil pump is designed to pump in either direction!!!. also the screen that you talked about, is the oil pick up screen. you did not remove the cap that holds the screen in place. there is a spring and a magnet behind the plate. this compressor failed due to poor oil return. the crankshaft bushings are worn , if you look at the rotor you will see where it was rubbing on the stator slots( bluing is gone). the rod broke first, then the piston ( from suction pressure) forced the piston down and hit the crankshaft. all of this could have been avoided by installing a" OIL PRESSURE SAFETY SWITCH" and a "OIL SEPARATOR"!!!! 97% of compressor failures are due to an "EXTERNAL REASON"!!!! this type of compressor is hard to "SLUG" with returning oil or refrigerant, being that it is refrigerant cooled anyway!!!

How do you get that copper out,

Enjoyed this one pretty cool😎✌️

Good one Bill 👍

hope u have correct diagnois

when i push my contactor manually the fan come on for a second and then the breaker trips. i disconnect the compressor but kept the fan connected push the contactor fan works fine and breaker is on. what parts of the compresor that are electrico that can go bad. my Copeland compressor is for a walk-in cooler. please help

Good 👍 job

One more rotor like that and you would be well on your way to making a stationary belt sander.

What type of refrigeration system uses this compressor?

How is the copper worth in one?

Next time take it apart with some Tannerite and video it !

So just a dingleberry hone and some new seals and she’s back in service? 🤣🤣 I wrote this just as you started re balancing the crank with the hammer....never mind she’s broke now 😂😂

Are compressors interchangeable? My condenser is ssx140421cb with compressor ZP31K5E-PFV-830 which has gone bad. I bought part ZP42K5E-PFV-800 as a replacement. Will this fit without any issues or cause damage?

I bet that the first thing that you do when you get a new mattress is pull the tag off that says do not remove.

I found one of these, it’s in great condition. I have no idea what to do with it.

I've a smaller one of these(was from a walk in freezer, still big... far as I know still works); you think it can be used as an air compressor? ** my thoughts are add chinese vfd and air filter? any pros/cons?

👍Eeegxxcellent Master!

Didn’t know Billy gibbons did refrigeration

Now waiting for rebuild video

i loved seeing the guts ,, grate video.

👍👍👍

Now put it back and give it back for rebuilt to be used again 🤣

Educational autopsy Dr.

That was a easy fix, before you got in there with the hammer and grinder. Some third world countrys accusing you with blasfemy.

There are 4 good things you can make out of that compressor. A curb monument out front of your house when someone hits it tell them i hope you have good insurance. You hit my 20 thousand dollar curb monument and you will never find a curb monument like the one i have your supposed to have control of your vehicle at all times. Or you can use it for a boat anchor. Or a flower pot. Or Definitely a paper weight like you were saying in the video

I like it. Waiting for you to destroy 👊a gas combi oven The Same way.

Catastrophic failure! Long time since I saw the insides of a Coplematic!

Send that sucker down here i'll fix it up as good as new!

discus compressor

I hope you use a copper faced hammer when you're actually repairing one of those ;)

At 08:38, yeah she broke...

Sir model number piz

#97 thumbs uP

And to think a simple couple of hundred dollar accumulator could have saved this many thousands of dollars compressor!

I bought a house and the garage had a Copeland compressor with the product number KAJB.-010ECAV215 on it. I don't really know what to do with it tbh.
