Help with old Sears compressor.

A friend has an un-working Sears compressor. It looks like the knob that adjusts the output pressure had been broken and put back together without all the parts. If anyone could lend some information on how this valve should work I would appreciate it.

Picture 1: Tank under pressure with no outlet pressure.

Picture 2: Pieces of the valve/knob. I'm not sure if that's the correct order. On the far left is a diaphram type object.

Picture 3: Location of diaphram.

Picture 4: View of "complete" adjustment knob. The brass "nut" is reverse threaded on the shaft of the silver piece in the second picture. As the knob is rotated clockwise, the brass nut travels in towards the diaphram.

The part that seems to be missing is between the diaphram and the brass nut. There is about a half of an inch from the diaphram to the nut at it's closest. I inserted a 9mm socket in the knob body and that seemed to help a bit, meaning I was able the pressure the output side, but not enough to make it workable. Regardless, I think the compressor needs a new valve/knob assembly but I think this it might be older than me.

I don't know if Sears still carries parts for this old compressor as I haven't checked there yet, but before I do I was hoping some of you might lend a little advice. Maybe there's a parts supplier out there you could point me towards.

thanks,

Jim

Have you tried contacting Sears? Normally, they can help out the most and have most of the replacement parts that you will need....

Like BetterDays says try Sears. Go on to their web site and go into parts. Put the model number into the proper area and see what comes up. They're pretty good about having the parts lists and diagrams. Give a try. Nothing to loose everything to gain. I've had good luck finding parts for things.

Also, that valve setup looks similar to the one that's on my compressor. Maybe you could up grade your valve for a newer model. The valve and guages on my compressor just look to be a newer style, if you know what I mean.

Hope I've helped a little.

Thanks guys. I guess Sears would be the place to start.

I had one go bad and Sears quit making the part. I kept watching on ebay and found something that worked.

Toss it and put a different regulator on it?

Some T fittings, close ******* and a regulator, swap over the pressure relief valve, and viola! it works again.
