its amazing that these little units do so well and all re-build parts are available.at first they were all going to blow up killing air gunners,breaking down and have no support.the cheap Chinese compressor that can pump rifles in 35 seconds.

Ken, did you find any fatigue from when you ran it hot ??
i dont see any discoloration but, i cant see no good either

Bob, how many hours run time do you think you have on the compressor?

Ken, nice write up on your rebuild. I purchased my compressor together with spare parts one year ago and it has not failed yet.
I have been keeping track of the fill times and it is still going strong. Last summer it as used continuously to keep my grandsons happy.

Bob, if it wasn’t for the compressor overheating, this write up wouldn’t be happening and now I know how the compressor works internally so it a win win for me and others to learn by😎 I was the guniea pig when I first posted this thread buying this compressor and now posting the rebuild of this compressor. 😳 btw would buy another young heng if for some reason I need to😎. I think this compressor is that good because I bought another yong heng while in the Philippines 😎

Thanks for posting pictures of your rebuild. Mine looks very similar inside (which isn't surprising). Now I want to buy a YH piston just to try it

Tweeter · « **Reply #1465 on:** March 17, 2018, 02:29:21 PM »

Do you guys leave your water hoses hooked up even if you aren't going to run the compressor for a few days? I can't see it hurting anything?

bandg · « **Reply #1466 on:** March 17, 2018, 02:49:05 PM »

I have left mine for quite a few days but it can get some biofilm started after a while. Probably would not hurt anything.

John no fatigue or discoloration on the parts. What failed was the second stage of the compressor. Pictured is the piston with a shaft I used a letter opener as a pointer to show everyone that 2 of 3 o-rings where broken / brittle from I’m guessing when it overheated. The good thing about this compressor is the o-rings are already included with the spare parts that come with the compressor for a one time rebuild if it came to that. There isn’t much info on what the o-rings fit😳 I will take a picture of the o-rings so everyone will know what the o-rings look like hope this info helps those who have this compressor that may need this info in the future😎

Looks like the parts can be interchangeable😎

Does it look like the second stage rings would be difficult to take off and change? From what I could see, you changed the complete head unit with pistons, correct?

Still have the original topend. Replaced it with a brand new topend for $88. Didn’t know what the o-rings went to until I open up the topend is when I foutout that there is a complete topend rebuild kit with the compressor. I personally haven’t tried to replace the new o-rings but plan on rebuilding the original topend with the o-rings. Will post how the o-rings replacement goes.

Thanks, really interested in seeing how hard it is to replace the second stage piston rings.

Ditto on what Bob said Ken. If I do get me one of them Yong Hengs I'll be baby sitting it when I first get it. A lot of the people are also getting the non auto stop one's too. They don't cost as much without but if you're just filling a gun it won't take long anyway.

I got my Vevo compressor on ebay for $281 with free shipping shipped from Ontario, CA. Looks pretty much like the Yong Heng compressors but it is 40 Mpa not 30 Mpa. I am still learning it at this point. The manual is seriously lacking. I bought compressor oil at Harbor Freight for $4.57 for a 32 ounce bottle.

Ok folks I drop the dime , ordered one from AliExpress. I ordered the 110 volt. I hope the water pump is 110 volt, otherwise I will have to go to chinamart pet section and buy a pump? The compressor $160 and some change. Shipping $144 and some change. I click on buy it now and the price jumped to $179 and some change. Got the discount coupon $4 and the total shipped was $ 324 and some change. I hope the compressor is package well for the journey across the pond. I will have to wait to open the box after April 5 and test review this littleness compressor. In the mean time bh1976 I await your test results as do our audience 😎

Seems like it was going to last forever. This morning I attempted to top-off the PRod and it failed. One side of the DPDT off-on switch has a bad contact..
I could jury-rig a switch, but I found a Holtsville, New York EBayer that had one switch left in stock. It looks like it might fit..

avator · « **Reply #1475 on:** April 28, 2019, 03:30:08 PM »

Yep, I fried the switch on my Vevor and borrowed the one from my MKII while it waiting for a high side seal replacement. I'll order a couple and keep a spare.

Ken did you ever replace your top end rings? I did mine a few months back and it was a major PITA! Just wondering how someone else went about it. I had to soak my rings in almost boiling water to get them to stretch enough to get them on the piston. Then ended up using a fuel line quick disconnect tool as a ring compressor to get them to slide into the head.

I bought the shaft with the rings already on it and just replaced the whole thing!

Ditto did the same thing. Still on its first rebuild since I burn up my compressor by forgetting to turn on the water pump. Now I use see thru water flow wheel that spins. Plug both into a power strip that I turn on so both come on at the same time and I watch the flow wheel spin as well as the temp gauge. I have had the water pump quit working on me and the only way I knew was by watching the temp go up hence the water flow wheel 😎

Hopefully I won't have to replace the rings again for a while. I think next time I will just buy the assembly with them already installed. Mine was never overheated. I had developed a leak on a fitting on the hose coming off my gold filter. Thought it was the compressor at first. Didn't discover the leak until after I had replaced the rings.
