Help identifying old green compressor

I just picked this up from the side of the road. Everything seems to be free.

Motor and Piston wheel spin freely and I can hear the piston pop so I think it is worth trying to fix but I cannot locate any tags or labels that would help identify it.

When I picked it up water was swishing around and it would not drain so I wonder if that is why it was thrown out.

I removed the drain plug and poked it with a piece of wire and oil sludge started pouring out, on the plus side, very little rust came out so maybe the sludge protected it some. I am sure I got close to half a gallon out of it and it is still slowly dripping into a bowl.

Anyway, I figured if I can fix it then it gives me a second smaller compressor to use.

The only marking I can find is that sticker on the side which I see on Wards and Sears compressors and the tag on the Doerr motor which seems to be a popular motor on compressors.

Any help getting a model number for parts would be greatly appreciated. I would like to do a complete overhaul on the gaskets, seals and rings.


Possibly this one?
by: Chris

So I was looking at compressors on craigslist in the hopes that I would find one that looked like mine. I found 106.153380 that looks identical.


Part #46 looks exactly like mine and I do not see the same part on any other compressor. If that is the case than the sad part is that the replacement parts to overhaul with new gaskets and rings seems to outweigh the cost of buying one in decent shape to start with. Just not sure it will be worth the time and expense. What say you?

I may end up parting it out and keeping the tank for extra air.

My existing compressor is a 5HP on a 22Gal tank so I am sure it has more than enough to fill this 10-15gal tank in tandem as well.


Piston rings and stuff

What? Under a hundred?

If the motor is strong and you can get the pulleys lined up, I think you’ll have a $400+ machine…

The fact you can even get parts for it says a lot.


SpeedAire, AKA Campbell Hausfeld.

That’s an old Campbell Hausfeld VT series pump. Very simple to overhaul, you just have to know which style you are building. I believe the green paint makes it a SpeedAire unit, sold by Grainger.

I would be VERY wary of airing up any old tank on a compressor I found by the side of the road. I shudder sometimes when I see the “amazing” compressor people have gotten for a song. It looks like a time bomb. And I have seen air tanks catch fire internally from the oil residue in the bottom.

If any tank begins to leak, toss it immediately. I don’t care if you fixed it with a braze or a screw or chewing gum, it is waiting to kill you or someone you love.


I agree

I agree with what you way about a leaky tank. I got very little rust out of this tank when draining and will be doing some more cleaning on the inside. I will likely fill it with hot water and dish soap to break up the oils as much as possible. I am sure I will run this through a few times before the water comes out oil free. I also will test the tank by filling it with water as much as possible before filling it with air. The water will not compress so if there is a leak it will be a water leak with very little air pressure behind it pushing it.

I am going to try to break the valve chamber down this weekend and see where it stands. I found an overhaul kit of Ebay for $60 that covers the CH compressors in several different variations but if I can nail down the exact model when I open it up I think it will better my chances of being able to get one of the $40 kits instead. I am getting close to about $100 for the over haul. I may still do it just to get it under my belt.

Is there any way to see how much the tank has rusted out or to gauge the thickness of the tank? If it is a leaky tank I will likely take the tank and turn it into a forge/foundry. Seems like it will be a good size for that.


No Idea How To Gauge Tank Serviceability
by: Anonymous

Short of ultrasonic testing, I don’t see how you could accurately gauge how much the tank has corroded over the years. If I remember correctly, most of the overhaul kits for these pumps included the proper filters for several different versions of the pump, but you should try and find out exactly which one it is to be on the safe side. I would look to see if there is a date stamp on the tank certification label. It looks like the original pump, so the date tag will likely be from the same era as the pump itself, which should narrow down the part numbers considerably. There are still quite a few parts available for older compressors on the Sear parts website, so maybe check there as well. Little know fact: Sears used to sell Kellogg compressors in the past, and there are still Kellogg parts listed on Sears parts website as well. I know they used to use Kellogg compressors in their service bays as well, as I used to do the service on a few of them. No matter, as Kellogg is back in business anyway, and there are many aftermarket sources for Kellogg parts as well.


Lots Of Old Sear Compressor Parts Here:

I’m sure you will find your model in there. I think I already found it just scanning through quickly.

Thanks guys, I did find some parts from Sears I believe but they charge way too much for their stuff so I am trying to source my parts from more affordable options. As for the plate or anything else that could be an identifier on this compressor, I cannot find any. Either they rusted off, broke off, were removed or were chinchy stickers that did not stand the test of time.

I am going to try and pull the compressor out and put some fittings on it to fill it with water and get it under pressure to test the tank before putting much more effort into it. For the overhaul kits, I did find one that has the same filter on Ebay for $40. The filter is want called my attention to the kit. The rest have filter that are 4.5″ x 1.5″ x.5″ but mine is a 4″L filter so I bet that is the correct kit for my compressor. If so that is $20 saved there. I would like to get the entire thing sand blasted too so I could put a fresh coat of paint on it, but that would be a luxury not necessity.
