eBay compressor

Hey I'm smarter than I look, what can I say.

That is a very good idea if its ok with you I am going to copy.  Now did you do this just to cut dwn on the amount of desiccant used or to stop the desiccant from making contact with filter ?

That makes 2 of us.

Go ahead and copy it up. I bought a 5' length of tube just in case. I did have to make a second one because I cut the first too short.

I made it for both those purposes. Kinda makes a filter cartridge this way. Also to cut down on internal volume so it doesn't take as long to pressurize.

Killfire, I am thinking about taking apart my compressor topend off even though at this point, I have zero issues😳. Curiously kill the cat I hope not😳.  I am trying to understand how this little compressor works. Just wondering if I take the topend off, can I put the cylinder head back on or will I need new parts? Just curious 😳 I know if it ain't broke why fix it😎

You can do it but if there's nothing wrong yet I wouldn't. I definitely understand the curiosity aspect haha. The only reason I suggest not doing it is because it's kinda difficult to get things mostly centered back up. The paper gaskets are pretty thin as well but you can buy some similar raw stock from the auto parts store and cut some new ones.

Don't do it, It's a trap.  lol.  But seriously, If you want to see into its guts watch this video.    The inner workings are very simple and totally servicable or you can purchase a new head if for some reason you ever mess it up.  I'll tell you from experience though.  One of those inner cylinders, where the low pressure air goes into the high pressure area, is filled something to prevent particulates from ever getting to the second stage.  That stuff will fall out if you aren't careful... you've been warned.  That cylinder is linked into the low pressure bleed channel on the right.

The only thing I haven't found for sale by itself is the motor. Just about everything else I've found replacements for.

When you say the motor, what do you mean?

[Killfire]

The electric motor that drives the compressor.

[Jman2311]

If the motor goes and trips overloads often, it is likely one of 2 things.  Either a degraded capcitor, or bearing failure.  If anyone has a failure of their motor, I do that sort of thing for a living and can probably help.

From what I saw three cap should be easy to replace and at least the motor has ball bearings.

That's what I'm talking about, members on this site are willing to help out with info on where to get parts and some common knowledge on how what to do if and when the compressor needs parts. Team players👍🏾
The more I use this compressor the more I like it😎

Informative video on the tear down on the two stage but would have been better if he would have gone down to the one stage

Ken, if you've ever been inside any piston engine it's pretty but the exact same. Aluminum piston with rings and a connecting rod. The only difference is the brass piston on top of the aluminum.

https://m.aliexpress.com/s/item/32793617028.html?trace=wwwdetail2mobilesitedetail&productId=32793617028&productSubject=cylinder-piston-and-rocker-as-picture-1-set-lot&spm=2114.13010608.0.0.bmNhnN#autostay

That's the low pressure cylinder and piston.

Also I think someone mentioned adding a dessicant pack to the inlet. You can do it but it dramatically cuts down on the pump speed due to restriction on the intake. You also can't "boost" it by running pressure into the inlet either. The motor doesn't have enough power to compress already compressed air.

I haven't even looked at my bearings yet. Are they sealed bearings?  If so that is awesome. No need to grease them.

Or does it?  Challenge accepted.

Ken,
Correct me if I'm mistaken, but from previous posts I assumed that  you have the Yong Heng compressor? It looks like a different configuration than the Tuxing. Is there a similar video out there geared towards rebuilding the Yong Heng? I am presently torn between the cheaper Yong Heng and the more expensive Carette. I think the Yong Heng would be great for topping off my PCP guns but if I decide to get a SCBA tank, the Carette might be a better choice. Decisions, decisions.

[Killfire]

Jeremy, I want to say they are sealed but I'm not 100% sure.  If you can figure out how to boost it let me know. All I did was buy some adapters to hook up my large air compressor to it. I think it ran at like 10 psi but not very well.

I personally regret buying the Tuxing compared this this model of Yong Heng.  https://m.aliexpress.com/search.htm?keywords=4500psi+compressor#/
Many sellers call this the boutique model.  The reason is the dual oil water separator/bleeders.  If oil is coming from anywhere it is from stage 1. I think the young Heng of this configuration would do better at getting rid of oil from that second stage where it becomes crucial that no oil, even the proper iso vg 150 oil, gets there. Also the condensate has more area to pool up in those separators. Only downside I can see is that I bet that high pressure bleed screw gets hot, real hot.  Otherwise the guts are the same, just different channels between stage 1 and 2, and 2 and tank/gun. 

Mind you I don't have a Yong Heng so I am speculating on videos and available parts I have found. I may get one in the future and run 2 small compressors in tandem for faster fill times for medium sized tanks or just a back up.
