regulator valve stripped

by Lonnie Winkler
(Lexington , SC, USA)

Please help. When can i find regulator parts for a Kobalt 5.5 gal. compressor. I'm considering removing shaft (stripped) and re taping whole and simply use a larger bolt. email: smakster01@aol.com

If you are talking about the regulator adjustment knob being stripped on the adjustment shaft inside the regulator, finding parts will probably be almost impossible, Lonnie.

Visit the store, buy another regulator similar to yours (same brand if they have it which I doubt) and use the old one for parts for the new when it wears out.

Cheers,

Bill

Kobalt K7060HFV unloader Valve discharge tube blowing off?

by Josh

Hi Bill,

I have a 60 Gal Kobalt K7060HFV. I'm having problems with my unloader valve discharge tube blowing off from the check valve.

The pressure switch side holds just fine. I've tried using a hose barb with a hose clamp, and I've tried a quick connect push on fitting. They both have blown off at about 110 PSI. The compressor continues to run however until I shut it off. Any thoughts or suggestions? Any help would be greatly appreciated.

Hi Josh... hmmm that's an odd one.

To be sure I understand, we are talking about the line that comes from the pump head down to the check valve, not the line from the check valve to the unloader?

Things that might cause this are a partially plugged check valve creating back pressure in the discharge line, or a faulty fitting where the discharge line enters the check valve.

I cannot find a photo of the Kobalt K7060HFV to better identify the components.

Assuming that the line from the pump head to the check valve is copper, to prevent this from happening I would consider using a flared fitting where the line enters the check valve. You'll need to beg or borrow a flare tool, get the line nut, and an adapter to allow you to connect a flared tube to the adapter, and then the adapter to the port on the check valve.

If, however, the issue is not a weak fitting, but rather too much pressure build up, securing the line with a flared fitting will only mean that the back pressure problem migrates elsewhere on the air compressor.

Cheers,

Bill

1.5hp blowes fuses?

Kobalt 10 gallon digitec air compressor

Kobalt 10 gallon digitec air compressor

The first time I used this compressor trying to fill a car tire it shut off, at the time I thought I had overheated it. Tried to restart no success. I removed the top and found the wires that go to the fuse were melted.

I repaired the wires, the fuse was good, however when I try to fill car tires I get about half done and it blowes another fuse.

Frustrated. It is a 1.5hp eith a 10 gallon tank stand up.

Rick, when you are using this compressor, are you powering it with an extension cord and the compressor power cord, or is the compressor plugged into the wall socket directly?

I added a photo. Is this your type of compressor?

Poping sound coming from Kobalt K7580v2

by walt
(GA)

Kobalt 7.5hp / 175psi, 240vac, 20a breaker, 4 years old. Pumps up fine until it reaches 100psi. At that point it begins to make a very disturbing poping sound. It is difficult to explain, so I have a 40sec youtube video if you will accept this method of explanation. : http://youtu.be/J-Zc8QhoBBk

Thanks for adding the video, Walt. Yeah, I heard the popping as the compressor neared cut out.

I wonder if it is the PRV popping off air pressure? Maybe drain the air until the compressor starts and monitor the PRV to see if it's popping off.

Another thought, check your unloader valve when you hear the popping sound too. If air is blowing out of the unloader valve intermittently, that could be the source of the sound and would indicate a leaking tank check valve.
