Glad they gave you some money back. I was going to keep pushing the issue with mine to get more money back but decided to not get greedy If you read their return policy it states that YOU are responsible for return shipping so I didn't want them to say Ok, just send it back then lol. They were good to deal with.Did your compressor arrive with a little oil in it?
Mine came yesterday . Wish i had seen this thread before ordering , was expecting the normal yong heng just without the stickers and was freaking out when I opened this up and saw the differences . Ordered from bigvaluehotitem on ebay from Ontario CA . Oh well , we will see how it goes . Not going to run it till next week after the filter arrives , may tear it down this weekend and check out the innards while i wait . Ordered the big double filter , probably overkill but cant hurt . Thanks for posting the link to spares . Couldn`t stand it . Just tore it down and found a free bonus screw loose in the crankcase and some rust in the head , glad i tore it apart now .
I have been calling my compressor a yong heng but it appears to be some sort of clone maybe? Looks alot like the yong heng with a few major differences. Obviously no Yong Heng written on the side, the small hose filter is a bit different, the burst disk sits directly on top of the second stage, water hose connectors are different and the major difference is on the inside. Mine doesn't have o rings on the second stage, it is some sort of plastic bushing which I'm sure will be a nightmare to find a replacement for when this one wears out. May have to just see if someone can make me some?I can't complain really because the ad that I bought it from called it a Vevor compressor but the picture they showed WAS a yong heng. Another member here bought a Vevor compressor from the same seller and said he actually received a yong heng. Thats what I was really hoping for but no big deal as long as it works. He did say that his came with a small amount of oil in it as well so I'm thinking that they test them before shipping and can't drain ALL of the oil out. Mine just happened to spend most of its time upside down which gunked up the top end.Has anybody else seen a compressor like this one? I am a bit concerned as all the reviews showing the yong heng as a safe little compressor mean nothing now. Who knows if this thing will hold up under the kind of use the yong hengs do? I will be filling to 3500psi for awhile to play it safe.I'll be happy if it lasts me the summer and then I'll either get a REAL YH or maybe the AV Nomad from pyramyd air (if reviews look good).
Made a discovery! Mine appears to be very similar to the Ace Eagle compressor.

Quote from: Tweeter on March 11, 2018, 07:09:19 PMMy god does the air that comes out of these things stink though! Can't wait to get some extra filtration to try to cut down on the stank lol.I never want to smell hot compressor oil again in my life. Its so bad that I have to hold a ballistol soaked rag over my nose to mask the stench, thats when you KNOW its bad! I need some oil that smells like, leather, dryer sheets or even strawberries Tweeter, the fact that your compressor got shipped upside down and with some residual oil in it indicates that oil seeped past the pistons. You'll probably have less oil smell after the residual oil burns off.A friend of mine has an Air Venturi compressor that costs $1299. It puts out an oil smell while running and lots of white oil/water mix comes out of the moisture dump when he manually purges the moisture drain. All of the Yong Heng/Tuxing/Air Venturi direct drive compressors are pushed at high rpms to achieve their fill speed rates. A consequence is that they tend to burn oil. My Carette is belt driven at much lower rpms. It has a lower fill speed than even the Yong Heng/Tuxing mini compressors. The upside is that it never smells of oil, it doesn't even have high pressure piston rings, and it puts out about 1/3 the noise level and vibration of the others. I've run it for 10 hours beyond the first 5 hour oil change and the oil in the window hasn't darkened a bit.

BTW-I just spoke with my friend who originally purchased it. The REASON he had concerns with it so quickly (after only 45 seconds of run time), was,...1- it was not the Yong Heng model that he had actually ordered, and it did not match his existing YH compressor. (note the different plumbing pipes on the compressor cylinder), as comparred to the YH that is plumbed quite differently, and has the one pipe coming straight out of the top of the cylinder head.2- when he did run it for the 45 seconds,... the heat rose at an alarming rate, and within seconds it was far hotter than his first YH compressor. (yes, the water was running prior to turning on the compressor)FWIW, he had to open a dispute/case with ebay, before the seller (Sevan) would offer a refund. He did also tell me that when he received it, there WAS some oil inside of the box, so that might indicate it spent some time upside down, and possibly has oil in the cylinder just like the OP found on his.opening the cover back up now to see if there is some mechanical debris, and if none is found, I guess I will be opening up the cylinder head for an internal inspection.
I just found this thread and am subscribing in hopes of learning something on these "clone" YH compressors. I received one of these compressors from a friend who experienced similar issues as you all have described.It has less than 60 seconds of run time on it and quit working. The white label on it says 110v and it has the 110v plug. I have read through this thread and see that it has been said the chinese 220v power cord is the same as our (american) 110v power cord ? When it is plugged into 110v, and I turn on the switch,... nothing happens. Yes the red light inside the switch is on, but the compressor does not run. No Hum, No buzz, No sounds or electrical smells of any kind. Also, I notice the temp readout DOES read a temp, even with the unit NOT plugged in. apparently there must be a battery inside ?I have read where some folks have had a relay burn up and needed to replace it... and I also read in this thread where a "reset" button was found on the relay. I will remove the cover and check for this "reset button" in just a few minutes. I just wanted to get into the thread conversation in hopes that maybe one of you have some ideas on what I may need to look for once I have the cover off.I will return back here shortly, and report my findings once the cover is removed.I guess my first question is, Might it be possible that it is labeled as a 110v, but is actually a 220v ? And if that is so, then what would be the best way for me to determine or verify this ?Thanks for any help and/or suggestions.ok on edit-I found the reset button and it was popped. I pushed it back in and hit the power button. Motor did make a humming sound, but did not spin. I cycled the power button a couple more times and it eventually did begin to spin. I only let it run for a couple of seconds and turned it back off. Then tried to run it again, and the motor would not spin, and popped the reset again. it would appear there is something causing the motor to bind up and not spin freely.I will remove the cover again, and see if I can determine whether the "binding" is a mechanical debris in the motor itself,... or if is possibly a hydraulic issue with oil in the compressor piston.
Oddly, this model of compressor does not have a relay inside in cover.The power lines run through the resettable circuit breaker, and straight to the motor.

Only thing I might have done before pulling head is to bypass the relay and try it to rule it out as a problem by connecting brown and green wires together, if the wiring is the same as on mine. Good news is these machines are simple in design and the parts are cheap and available. Good luck.
Jim,Yes my circuit breaker is in the same place as you show, but my compressor cylinder plumbing is the same as the OP's pics.Yours looks more like the Yong Hengs I have seen more commonly.
I am certainly no electrician, but it DOES have a cylidrical component inside that is about 2" in diameter, and approx 4.5" long.it has some writing on it that says 250VAC 50/60 Hz. I will try to get some pics posted soon, but my Photobucket account is not playing nicely since they changed the PB rules.
Actually that picture was from the seller's ad, not the one I received. I just used it to illustrate where the reset button is on the units that have them. Here is my actual compressor. I bet it's more like yours.Quote from: Gertrude on March 25, 2018, 09:54:42 PMJim,Yes my circuit breaker is in the same place as you show, but my compressor cylinder plumbing is the same as the OP's pics.Yours looks more like the Yong Hengs I have seen more commonly.
