You won't BELIEVE what's wrong with it! | Rolair "The Bull" Air Compressor Trash Pick
Вставка
- Опубліковано 4 сер 2023
- I picked this Rolair (The Bull) 2-HP 4.3-Gallon Contractor Twin Stack Air Compressor Model FC2002 MK246 out of the trash the other night. It's clearly gone without routine maintenance or care for a while and was left in very filthy conditions for some period of time before it was set out to the curb for the trash man. First question is, can we get it running? Second question is...is it SAFE?
We'll troubleshoot why BOTH the cold start bleeder valve and the unloader valve attached to the pressure switch are bleeding air at startup and why the unit fails to build any pressure. We'll also discover that the unit had a lot of water inside the tanks. Could it be a faulty cylinder head gasket? Reed valve? Check valve? Weak motor? Or is it something else very stupid and simple?
These compressors are $350 new, so this will be a score if we can get it going. amzn.to/45yGgZJ
This same compressor is also made under the names Jenny Air 2 Go A2G246-HC4V-115/1 and Emglo E810-4VR. These troubleshooting steps will work with those models too.

The best part is the night ops filming, with flashlights and whispered talking.
Trash day in your neighborhood is a gold mine.
Satisfying and informative
👍✌😎 Think I might drag my Compressor outta the shed and give it some love. Been sitting too long to just drag out and use. Great info brother. Cheers 👍✌😎
You should
Ya gotta drain those tanks on a regular basis.
The frogs agree to your awesome find! 😮
Them little buggers mudded over my key slot on my mower and the gas feed tubes on my grill.(anything left outside is fair game)!
They'll even clog the drain hoses on your vehicles a/c system.
I try to cover everything up that's left outside.
Another fine resurrection.
Awesome. My portable compressor came off the side of the road too. I've been using it now for 24yrs! Only problem it had when l found it was the exact opposite issue. The air filter assembly had been snapped off. The plastic threaded part was still screwed in the cylinder head. I ended up just making one out of PVC pipe odds n ends l had laying around. Stufffed it with part of a foam sponge l cut to fit. I give the sponge a light squirt of WD40 once or twice a year to help trap dust.
Can't beat free.
Another cool find and repair. Insect clogs are common in gas grills as well
Never owned a gas grill but i see a nice one on the curb every other week, literally.
@Fixologist1 not sure where in the south you live but judging what your area trashes, you must be in a wealthier area. You never see this stuff on the curb in rural Oklahoma where I live. We use shit till bitter end
@@contrabandjoe7974 I live on the richer end of town, but I see stuff all over the place. It's just sheer laziness and lack of curiosity.
Air has a lot of moisture in it. Never leave a tank with air in it or you will rust the tank from the inside and contaminate what you are painting or even putting air ( and thus water ) in a tire . Got a pancake compressor and it has no air in it right now.
You should do so as well. They also make a moisture trap you could add to the outflow connector to the tank but make sure the relief valve points down on it like mine. Very necessary for painting small plastic models as you want the dryest air possible. Great job going over it Brad to find the real problem in the air filter.
Thanks for all the excellent advice! Yes, I let all the air out of my compressors after each use. and drain any water.
My biggest concern is one rusting to the point where the walls become thin and it explodes under pressure. It's extremely important to drain the air after every use and not let it sit full of moisture.
On that note, I make sure to blast the water out under full pressure with the release valve positioned at the lowest point on the tank. This removes more water than just leaning it over and letting it flow out from its own weight. For this reason, I prefer tanks with the release valve in the bottom, but some tanks you may have to tilt over while the air blasts out. It may seem trivial but it's a real safety concern as tanks have been known to explode from prolonged rust erosion.
For small model painting, it's almost more efficient to buy bottled nitrogen to power airbrushes, since it's nice and dry, and non-toxic. A high pressure nitrogen cylinder lasts a LONG time in this scenario.😉
Wow great find thanks Brad 👍
I have a compressor just like that, but mine had goop for oil. Changed oil, replaced burned up pressure switch, and it's been working for 5 or 6 years now.😉 I have 2 extra 10 gallon tanks hooked to mine for more capacity, and it keeps up with my air tools a lot better. I actually have a 2 stage Curtis compressor with a 60 gallon tank, but the motor is burned up and it's like $300 for a new one, so this is/was a temporary replacement that never got replaced yet.😄
Jerry rig that shit, baby!
lol, exactly what I was thinking dirt dauber? yep dirt dauber @#%&#@
Nice job Brad!
Reminds me of sling blade.
It out gas… 🤦♂️
There are a lot of time when the simplest problem is just that, simple.
Is it plugged up, did you put gas in it…😂😂😂
Wow nice pick man! Those little compressors are bad@$$! They push about twice as many CFM that many other compressors of that size!
These videos and this channel have become the highlight of my Saturday nights. Along with Shango066 and Usagi Electric (vintage computers and vacuum tube electronics), and Mustie1 (similar wrenching) on Sundays, and some similar others, it’s a great weekend of DIY video watching and learning. Just please don’t stop doing amps also, and I’m going to keep saying this, only because I care about your longevity with this stuff; please, get/build a work bench, and/or lift, and also, I will continue to “harass” you about doing a motorcycle or mini-bike, because I know when you eventually do, it will be amazing…
😊😊😊
I need to clean some crap out of my garage before I can build a proper workbench out there. It's stuffed full of crap right now. I need to work on that Jag that's out there and move that thing out.
@@Fixologist1 … THAT would be a great video too! I was going to suggest cars as well! 😊😊😊
Lovely logic and the "sleep on it" philosophy without doubt can bring about huge rewards. Sharing your sentiments there 100%.
I think our minds subconsciously solve problems while we sleep.
@@Fixologist1 Brad probably dreamed about killing mud daubers all night!
I’ve had that same compressor over 10 years. You can usually adjust the cut in and cut out pressures on the pressure switch. Mine cut in at 90 psi and cuts out at 130.
I’ve got another idea for you. See if you can acquire and figure out how to fix a dehumidifier (which is basically a small air conditioner on wheels, without the cooling aspect). I go through dehumidifiers like crazy (out buildings and such; extremely high humidity in Southwest Georgia), and I know whatever kills them has to be minor. They still run, but just don’t dry air any more (or very inefficiently). So I literally have a COLLECTION of old non-dehumidifying dehumidifiers. Maybe I should send you one to figure out, and then I’ll know how to fix the rest of mine. Almost no one is making videos about these repairs. It’s like a “Dark Art” or something… LOL!
I have a couple dehumidifiers. One I found on the curb. But both are in working order. If one breaks, I'll get it sorted.
Hey Brad, what a brilliantly put together video. Your videos are highly adictive, and they way that you explain things is just awesome. Love and light to you and your family. Paul from Bonnie Scotland.
Thanks, Paul. I'm glad you enjoy them, and I appreciate you saying so.
@@Fixologist1 your welcome my friend. I do some repairs myself, more so now that I'm medically retired. Keep up the great work.
Great find, I enjoyed watching. I got to tell you one thing, you would do yourself a favor and not be so quick ordering parts until you do your research and fully check things out first.thanks for posting
True. I did pull the trigger on this a little soon, but when I ordered I was pretty confident it would solve the probem, and reasoned that if it wasn't the problem, I'd still be out little money on a part I might need at some point anyway. But you're right. I'd send this back if I could.
You did good in the end, I dont have room to talk because I've done lots worse and lost lots of money.looks like you only lost less than the price of a decent meal. keep doing what you're doing, I can see you are getting better in every post. God Bless
Informative video. Thanks! You sound like that Brad the Guitarologist guy.. have you seen his channel?
Sounds like he stole my channel name.
being in construction most all my life I knew that was a rolair when I saw the color, that's their color, rolair makes TOL compressors, most your union jobs will use them, made in USA or were.. great pickup compressor . . . Emgo and Rolair are tops
Always the smallest problems that cause the biggest
Cool fix ! Wow, turn it into a decent buck 💲
Yeah, should bring a solid Benjamin, at least.
water won't hurt the insides of the tank, they get that way why they have the clear out valve, you can get a water trap and put it in between the pump and tanks that will eliminate water from entering the tanks.. if you need dry air
Off topic but, down here in south Alabama our Dirt Daubers build different kinda nests than the ones you showed. Ours build little mud pots. They're shaped like a bottle of good tequila. They even have little bottkenecks at the top. You'll see the kind you showed occasionally. But the little mudpot builders are more common. Like 100/1...
Interesting.
DOWN HERE WE CALL THEM "MUD WASPS" IN NEW YORK & NEW JERSEY ! IN CENTRAL
NEW JERSEY YOU COULD FIND SO MANY TOOLS, THAT WERE THROWN AWAY EACH YEAR
PEOPLE MADE SMALL BUSINESSES OUT OF IT.
see that brass valve with the ring right next to the gauge? tats the "pop off" valve, it will pop before anything bad happens to the compressor, basically opens up the airway and bleeds air, let it go till it shuts off or the valve pops off... yea 125-135 lbs is the proper range for a hitachi nail gun so 105 is low, too low for tools, I bet its a 160lb pump, don't let its size fool ya those are very nice compressors, very rugged as well
Go back to Amps and guitars
Wrong channel.. This was his 2nd channel, but now it seems to be dedicated to fixing odds & ends. 🤷🏻♂️ I'm sure there will be guitar & amp repair on his main channel.
You may wanna "go back" to "reviewing" his earlier videos explaining the new channel....
r u draining the reservoirs of water regularly?
Yes.
FYI, the easiest way to find air leaks is with a spray bottle full of soapy water!
Yeah but if it’s only leaking when it’s running it’s kind of hard to spray it with soapy water. Especially when air is blowing on it
