I am looking for any information on my compressor.it is an older opposing keystone compressor. serial number is U011502H.im not having any luck on line searching. A manuel or parts explosion would be helpful. parts sight might be good too..i'll probally need some.
 
I have a Keystone compressor also. Been in my garage since 1958 & was prolly used before that. Still works great; builds up to 150 lbs. pressure, where it cuts off automatically. They went out of business long ago but other brands use the same parts. I've never had a break down so can't help with specifics but find another brand that was built just like it & use that info. Look for those brands in old shops that've been in business for a long time.
 
I didn't find anything promising either. I did find something about their trademark being "abandoned", which I would assume means out of business.

A couple of searches returned old posts to YT. Nothing promising there either, that was back it '98. The only solution was for OTTO GAS ENGINE WORKS that can supply piston rings.

I would try gently dismantling it, see what you've got. You might find it's in better shape than you think. Many times compressors stop pumping because of carbon in the valves. Sometimes a good cleaning and refill with synthetic compressor oil will save one. They seem to have had a good reputation.
 
This might help ... YT Post from 2000 re: Rings ( http://www.dol.net/~dave.reed/otto.html ) .
