I got a compressor from my dad when he died and I used it rarely for several years. Last year when I let a buddy borrow it, it would not build any pressure. Well I just got around to tearing into and I found the reed valves broken off on the exhaust side. It also appears that the cylinder wall and piston were damaged from letting it run too long. My buddy started it and went inside, then got lazy and didnt make it back out to the garage for and hour or so. I can find the rod/piston rebuild, but the pump assembly is discontinued. I cant find the valves by themselves.

Its number 64 on the diagram

Does anyone know if you can retro fit another pump onto it (that still has parts available)?

Should I just call this one a parts compressor and salvage the motor for another project? Maybe "T" the tank into my new compressor so I have a reserve tank? Im not going to scrap it, but if I cant find any parts for it anymore then Im kinda SOL.

Also there is a service tag on it from 97 and It barely reads "will not build pressure". Im guessing this was an early model oilless and this was a common problem. Thats why they discontinued the parts...or they were all sold after they quit making all the parts

Do you have any pictures of the whole compressor? What are the first three numbers in the model number (this will tell you who made it for Sears)? After the first three numbers, there will be a dot and then the model number. 919 is the manufacturer's code for Devilbiss, who made most of Sears' compressors. Their website is devap.com and they are friendly to talk to for Sears air compressor parts. The compressor is not worth much, so keep this in mind before buying parts.
If it was me, I'd toss it and buy a new one.

+1 on that. It was a happy day when my crapman went bye-bye and I got a REAL compressor.

well in the past I havent done much work at the house because most of my tools are at work, but Im gonna start framing the new garage in a week or so, so I was wanting to get it running again. I plan a getting a bigger compressor once the garage is up. I even made a spot for it, but until then it would be nice to have something.

The model number is 919.152921 . The pump number is AC-0059. I guess I should have posted that earlier.

It stills holds some sentimental value to me, so Id like it to be sitting in the corner operational instead of just a bulky dust collector. I hear ya guys on investing too much in it though, but the piston/rod rebuild is only $40. So if I can get running again for under $100 I'll be happy. If not, well I guess Ill just resurrect it has something else with the parts and start saving the dollars.

here is a pic of the compressor. Ill contact them tomorrow and see what they say. Thanks for the link

bummer...devilbiss said there wasnt anything they could do. Im gonna try the guy that does all of my heavy welding and see if he can make a valve on the cheap. Its just a layer of thin springy metal. And if that holds and works good, Ill order the cylinder rebuild kit.

Thanks again for the info:beer:
