I would add the followings : 

- Reed valve blades ( 2 in a set ) at the top of the high-pressure cylinder 

- rubber gasket in the crankcase. It will shrink over time and you wont be able to put it back if you need to remove the crank case cover.

- seals set.

Sorry... I don't shop on Aliexpress. I order the parts directly from Yong Heng in China. May be some other members can help.

Try these suppliers. They have better prices than the YH shop.https://www.aliexpress.com/store/3112036?spm=0.8937474.0.0.52bf2e0e8XF66i

https://gzbjbf.aliexpress.com/store/1724244?spm=0.8937474.0.0.52bf2e0eJKBfeb 

https://www.aliexpress.com/store/5584107?spm=0.8937474.0.0.52bf2e0eJKBfeb Make sure you add the shipping when comparing prices. I've used the first two sites and have had no problems. I'm assuming that you are a fellow Aussie by the use of the term "pal".

With so many counterfeit Yong Heng compressors on the market, how does one know if they are getting an authentic version from these AliExpress vendors?

There are no counterfeit compressors. Even the Yong Heng is a copy of the earlier Davv pump. There are a number of similar units on the market but I have never seen a machine that is a true knock-off of a Y.H. meaning a machine built by another company with Yong Heng branding. I have seen Y.H. pumps with other band names printed on them because if you buy enough units they will print whatever you like on them. The vendors above sell parts for several different brands of pumps and don't always advertise what particular brand they fit but the YH parts are usually described as such. If you have a look at your own parts, you can see differences between them and parts that are made for other brands, for instance, Y.H. high-pressure pistons have three rings whilst Tuxing use four and Vevor use a different type of ring altogether. Brands like Hatsan and Air-Ventury use the same parts as Y.H. and Tuxing respectively. Some parts are interchangeable because they all share common crankcases but most are slightly different and won't fit as a single part but if you replace the whole assembly it may be possible, like bolting a Tuxing top end on a Y.H. block. As there are no counterfeit compressors, there are no bogus parts. The original equipment parts are so cheap, why would anybody bother to copy them? Here is an example of a Yong Heng made pump with a Queensland gun dealers name and logo on it.

I have one question about the screw (fitting) of yong heng. I need to buy fitting what is in the middle. There are two size. Upper one is bigger than middle. I need this in middle. Maybe right question for airgunsfun because I didn't find it on aliexpress.

The part in the photo is not from a Yong Heng pump. It looks like it may be from a V twin model from another builder. I assume that the screws that you are talking about are the pipe fittings on the top and side. You won't find them on any spare parts lists. If you want that part, you will have to buy the whole assembly.

 

[octavius]

Yeas Eaglebeak it's not from yong heng I did not know what it is called just this one part. I need only one this part. I explain you why. I have Simple version of yong heng because I bought it from Poland aliexpress store and there were any available. Of course I wanted Hardcover version. So, I bought from aliexpress already mentioned parts of the cyclone separator plus pipes etc. BUT when I opened the parcel from China I found there will be problem due tu simple version has those two "fittings" are in the same size bigger. But versions with the cyclone separator they have two different size of fittings. If I want to use my new cyclone separator I have to change one bigger fitting to smaller one due to piping...

OK, I understand your problem. Good luck with finding the right fitting. Perhaps you might find one at a specialised plumbing or hydraulic fitting supplier. I bet that you would be able to get one from Ali Express if you could work out the right keywords for your search.
