There have been several discussions recently about air compressors. As I had mentioned in another post, I picked up an older 2 stage compressor that didn't work. Needed valves. Finally got it all put back together today and took a few pictures. Sometimes a picture is worth a thousand words, so here are a few of the valve assembly on a Kellogg American 321 2 stage pump.

One picture is of the complete compressor - it is really heavy!!!

I had to make tools to remove the valve covers. Basically pins to fit into the cover holes. Three different style covers = 3 tools. I could have bought a set - for $120.00!!!!!

Finally here is a picture of the head from the underside. The manhole covers cover the valves - 2 intakes and an exhaust for the first stage, and one intake one exhaust for the second stage.

More to follow..

The actual valves are thin metal disks, held against removable seats by springs. Spring/seat orrientation depends if it is an intake or exhaust valve.

The seats can be replaced if damaged, but usually they are fine - mine showed no wear and were left alone after being cleaned off.

A valve rebuild kit (purchased online from one of many compressor supply stores) was bought (shown below) - basically new valve reeds, springs, and crush gaskets.

I also soaked the head and passages while the valves were out - getting all the gunk out of the passages.

On mine, the culprets were mostly broken springs. Also had one disk that was rusty and not seating well. Couple had gunk on them and were not seating well either.

Added new head gasket, and we are back in action!!

I always wondered what the inside of a compressor looked like. Thanks for posting the pics. Neat little tools you made.

Thanks for the posts and pics. Good it could be repaired. I have been looking for a good sized compressor, but everyone wants too much for them. Saw one I wanted but waited to long and it was gone. old 30 gal 2 cyclinder 75 bucks. Maybe I could get a none working one and rebuild it as you did.
