I just checked my Yong Heng temperature probe and found that it slides out very easily. I cleaned the probe and the hole that it slides in to and added a light coat of thermal paste and now it fits very snug. Thanks for the great idea.

Thermal grease, paste, heat sink compound, it's all basically the same thing just different terms... all though, not all compounds are created equally.

I did the same with mine. I just ran it for a few minutes not hooked to anything. Then did some short run time fills. After I had about 20 minutes on run time on it I changed out the first fill of oil to flush out any gunk left over from production. Its been running fine since then. I'm currently using the chemlube 751 in it.

I just ran mine.  Didn't do any leak checks or anything.  I did run it with no bottle hooked up for 10-15 mins with hydraulic oil and then drained it and removed the front cover and wiped out the residue.  Refilled with fresh and called it good.  Just be sure to always, always, always make sure there is water flowing to the head.

Thanks for the info! I'm thinking that a 5 gallon bucket should do the job. Add a big block of ice.
One thing that worries me a bit, is dropping that water pump in the bucket. If the case leaks, that might be a shock hazard.. Man up.

I got busy this morning and didn't get to many of my chores today. Have not started any testing yet,
since I wanted to test the dehumidifier in the basement. Don't want to run the compressor in 75% RH..
The dehumidifier is working poorly, so I'll be working on that problem before testing the compressor.

When draining the break-in oil, did it look dirty or was it clean? Dirty as sin.  Mine was a dark, turbid grey with metallic flakes swimming around.
I'm asking, because I see a bit of clean-looking factory oil under the sight-glass.
Maybe the factory testing oil already cleaned it out pretty good? Or not? Not.

After reading the tiny manual, about installing a gasket on the hose from the output port, which gasket should be used? It states to make sure the little white teflon/delrin whatever is in there already.  Mine was.
There's a unopened bag of them, what size/color did you guys use? Or should I just use Teflon tape?

Thanks,
Rich

Could get a plug in GFCI. Keep in mind, the plastic case has NOTHING to do with the sealing on the wires/magnets. The wires/magnets are potted in epoxy. On the other hand, this is a product of china.......

There is a GFI under the kitchen sink. I could use that socket and the SS sink to test for voltage leakage.
If it can run a while without failure, I'll feel safer..
When look at this thing, I think of the old space heater in the tub 007 trick.. "Shocking. Positively shocking"..

Okay Bizill, I have two of those white plastic aspirins w/1mm hole inside a bag and there was also one inside the output port..
Just like you said! I guess when they tested these, they just left that one in, and they don't seem to fall out while at sea..

Also got the the heat sink compound on the thermistor. Found my little oil funnel while I was looking for tools.

I'm going to be all set when I get the basement dried out (92%RH). It's been raining like crazy here..

Thanks,
Rich

Rich, be sure to break that compressor in with new oil for at least 10 mins with the water flowing through the head.  Drain all that nastiness while it's warm.  Actually, warm, cooled, doesn't matter as it'll flow out nicely.  If I were to do it over again, I'd do 2 flush cycles to get all the &^^& out, though it's not necessary.  I just like overkill.

I'll also have to check my temp probe to make sure it's snug as a bug in a rug.  I do know that my temp gauge display is undersize in an oversized hole as it vibrates back 'n forth a lot.  I'll probably address that as the optical illusion it creates to my eyes is funky.  It makes it look like the entire cover is moving all about when it's just the gauge display.

I also have a male to male foster plug with one side having a check valve in it from Air Tanks Plus.  It'll act sort of like a priority valve.  All I care about is not having to build pressure on the compressor/high pressure filter side and then time it so I open the scba tank when it's at about the same pressure.  This way I figure if my SCBA is at say, 3000 psi then I can open the scba valve and it'll hold the check valve shut and then when the compressure builds its way up to 3000 psi then the check valve will open on its own without me hovering over the gauges and scba valve.  Also when I am finished and go to bleed the system down, I can have it so that there is little to no backflow through the high pressure filter.  It wouldn't matter either way but sounds like one less step for me during filling and I lik that.

Have a minor problem with the gauge. Needle is bouncing around and when I bleed the system from filling sometimes the gauge will not return back to zero. Have to tap the gauge to make the needle go back to zero.the needle Reads 10 psi off from zero and I have to tap the gauge to get needle to zero. I'm going to have to get a new gauge that is liquid filled. I believe the liquid filled gauge will help with the vibration of the compressor while filling. The gauge still works but due to the vibration the gauge is not accurate any more. After all I have used the sh?)& out of this compressor since the first week of April😎 And it is still filling my guns and tanks to feed my addiction to these guns😳 I would advise to change out the gauge to a liquid filled gauge. The gauge will need to be the same diameter as the he one on the compressor due to the metal line the is very close to the gauge. So guys and gals, can you all find s gauge the would replace the one on this compressor.

Like the rest of the hose fittings, the gauge is M10x1.0 straight threads....

I didn't find a better quality gauge, I didn't look really hard either... I did order one of these as a spare and use my tank gauges for comparison.

EDIT:
Hummm, I just noticed. Your gauge is not glycerin filled? Mine is... Maybe they didn't use filled gauges in the early production models? Or, did yours maybe leak?

[shultz]

This is your video right? Can't tell if the gauge is filled, but, it does look exactly like my gauge from the few glimpses I got... it should have been glycerin filled from day one..

Yes my video. What I did notice on the side of the gauge is a black plug. Didn't really paid that much attention until now. Must have been filled with glycerin. Must have leaked out from the seller to me. Is yours liquid filled gauge?

Thanks for the link I'm going to say it was at one time glycerin filled  and I didn't pay close attention and notice the black plug on the side of the gauge. That would explain the bounce of the needle while the compressor is running. Going to have to find a gauge in the u.s. For faster shipping. The link you listed shows shipping from China and approx august 14 arrival date. If I can not find a gauge on this side of the pond then I have no choice but to order it.

[shultz]

Yep, if it has the black plug it SHOULD have been filled. Yes, mine is glycerin filled.

You can get glycerin at many pharmacy's, if the gauge is still working, just bouncing during run, filling it with glycerin will dampen the bounce. All the glycerin is in there for is dampening the needle.

pop the plug out, use a syringe if you have one to fill the gauge with glycerin and replace the plug.

[shultz]

Good luck finding a gauge locally with M10x1.0 straight threads... I didn't use my serious google foo, a quick search produced ZERO results.

Might be easier to find an M10x1.0 to either 1/8 or 1/4 NPT bushing. This would really open up gauge possibilities, make sure the bushing is rated for 6000psi though.

Thanks hmm, didn't know pharmacy's carried glycerin? Maybe the gauge has a leak? I found this one on eBay http://m.ebay.com/itm/2-Liquid-Filled-Pressure-Gauges-1-4-NPT-Center-Back-Mount-5000PSI-/121989997325?hash=item1c672ba30d%3Ag%3A7V8AAOSwfC9XO50Z&_trkparms=pageci%253A20d4ba2c-67f5-11e7-8f23-74dbd180809c%257Cparentrq%253A3d1bc8a915d0aa47cc7c62b0ffe6b769%257Ciid%253A24
I need a gauge that is 1-3/4" diameter glycerin filled gauge. This one is 2". If I buy this one the gauge will need a extended tube to get pass the air line

[shultz]

an example..
https://www.walgreens.com/store/c/africare-100-glycerin/ID=prod4118523-product

Either a leak or maybe it was never filled to begin with... hard to say.

you'll not only have to raise the linked gauge, you need bushings to get from M10x1.0 straight thread to 1/4NPT...

[kzz1kaw]

Thanks John for the link. Never knew what was in the gauges and where to buy. I learned something today thanks😊. Going to buy and fill first to see if there is a leak in the gauge and see if the needle will return back to zero before I ordered another gauge

[kzz1kaw]

I'm going to remove the gauge from the compressor and refill the gauge. I'll let you know if the gauge is leaking or not

[shultz]

Not sure what chain pharmacy's are in MI. I would think one of them would have 100%, clear glycerin on the shelf.


I did have my gauge stick once. I did some high side filter work and wanted to leak check. Pressurized to 2K and shut off the compressor. I didn't find any leaks, so I released the pressure, gauge stayed at 2K....

I turned the compressor back on, let it build pressure until the needle moved. Opened the bleed, gauge dropped to zero, then I shut off the compressor. Gauge has been working fine ever since.

I was reading in one of the various brands of compressors the manufacturer did away with the glycerin as it was not needed.  A forum poster decided to fill his anyway and ran into a few snags.  It may have been the Carette compressor.
