Yong Heng Last time I rebuild...ahhh..#6..#7 in 3 years

I bought the regular single cylinder Yong Heng during the Pandemic with the start of my PCP experience... I'm getting good at working on it....But it seems as time goes on new piston gets.me.maybe 5 refills on my 45 min scba tank from 3600 psi back up to 4200 psi..I pretty much stopped shooting my 510 Texan... I'm trying to muster up the strength.to rebuild one more time...I think number#7..I have been challenged in the.income department🙄...So.hopefully I can put a new piston,vale,gaskets.on more time... In a month if my disability goes through finally I guess ill upgrade to the Twin cylinder Tuxing....I already can work on it...Its in the budget under $400.00.... Much thanks to the members on the forums that helped and supported in learning how to use and repair a cheap Yong Heng.. 7 Yong Heng rebuild s probably slang 300 lbs plus of.510 slugs...

Where do you get the dual Tuxing for under 400? I see them at about 600 dollars. Thanks

Forgive my ignorance of YH compressors, never owned one, only know enough to have avoided them over the years, but...

Why not buy a different brand that just WORKS, and doesn't require rebuilds on a regular basis? With internal cooling. Like the GX line, or Omega? Not sure what a rebuild kit for the YH costs, but I'm guessing you've spent enough $$ and certainly enough personal time to warrant having spent a few $$ more on a CS4-I recently?
 
... Why not buy a different brand that just WORKS...
In my case I got my YH somewhere back in early 2020, I invested time and money into a learning curve, I have one spare still in crate and I always have spare parts in my drawers from aliexpress and I can rebuild it in an hour or two. Along all these years rebuilt it probably 5-6 times and my total cost is still well below $1000 including labor. The vibration meter dried out the battery somewhere back about 65 hours...I know I shall replace but wtf...
Now with this experience to start exploring again a new, the latest and greatest "oil less water less gizmos" and nobody so far actually collected 10-20 hours to proof that these better bang for a buck?
Of course if the money is not an issue I would buy some dive shop level pro compressor, but I am guessing even for a $5-10K unit can break just the same any time.

I get it, for those who have had them for years, I really do. I was just never stable enough (moved a lot) during their heyday, and in the past 4 years or so kind of gave up on the smaller China compressors, until I got turned onto GX by a friend. I can understand brand loyalty, and knowing what you know is a big driver, but at the end of the day... aren't we all after the DRIEST, CHEAPEST air we can contrive?

I understand that all of us operate within our own budgets/space constraints, and there is nothing wrong with that. But if the difference is $100~200, vs $1500-3,,000, I know what I'd opt for.

(My next step, should it occur, is to lease a nitrogen tank to feed my GX-CS4-I and ditch the filtration.)

Better the devil you know than the one you don't..... It only cost me usually $12-$28.00 to fix yong heng.. I'm not buying any small compressor to fill scba tanks..My .510 eats air fast lol. Hopefully my disability goes through next month...Finance come through and get a new compressor... 😀
 
13 hrs and going strong with my first YH. Hope to get 20-30 hrs before I need to rebuild. I try to baby mine, 10-15 min run time, sub 60c temp always, let er warm up a hair in the cold before shutting the vents to let pressure build, only filling to around 4k on my tanks.

I should order a piston just to have on hand, but if mine kicks the bucket within the next year during its warranty I'm tempted to just file a claim. lol.

I am distracted by the larger twin cylinder compressors as well. -BUT- I have two Yong Hengs, each 3 or 4 years old (the second came to me at a flea market of all places for $100). I have rebuilt both of them, one of them twice. Usually at around the 30 to 40 hour mark, that's a lot of air. I routinely fill middle size SCBA tanks from less that 3K to 4.2-ish K. My rebuilds have included piston sets, like $15 at Ali-express and o-rings. I did go WAAAAAY overboard on the cooling with large fans, radiator fans and more water flow. I have become good at tearing them down and putting them back together...maybe takes me an hour or so. When I do a rebuild, I order whatever parts I just replaced and 2 weeks later I have them. When I take one of them down for rebuild, I put the other online.

Sound extensive? It's not. And as I said, I have become good at maintaining them. I keep a shoebox sized quantity of parts on hand. To me the Yong Heng is a great value and I'll keep using them.
