I still check the board from time to time.

Glad to see that you're still around because I could use your expertise in identifying the pump below. There are no tags to be found. Obviously, it is a 2-cylinder single stage cast iron unit and the only numbers I can find are 59K10013R stamped into the lower casting.

So, I'd like to know the make, model # and your opinion as to how good a pump it is, how many CFM it should put out and if it is an expensive rebuild or not.

It was taken out of service because it was taking way too long to build air. Therefore, there is no internal damage to deal with and it always had adequate oil in the crankcase.

Whatever you can tell me will be much appreciated.

My service man says that appears to be an old piston refrigeration compressor pump converted to air. He does not know the brand but seemed sure of it's original purpose.
Sorry

As they say: "Don't shoot the messenger." LOL So, I don't have my gun out.

Not the news I wanted to hear but it is news after all. Does your service man have any advice? If I pull this pump apart, what are my odds at finding parts for it so that it can be put back into light service? I was hoping to get this thing going again for a modest cost and give it to my son-in-law to use at his hobby farm. He needs something to air up tractor/baler/wagon tires and power an air gun for repairs now and then.

I'd rather him having one of these older but solid units around than the noisy, hi-speed junk sold in the big box stores.

For the time and potentially the money, I'd look at one of the newer compressors. There is also the portability factor that could be worthwhile.

Depending on what he wanted to power in terms of air tools, get a compressor rated for continuous duty cycle if needed. Most compressors are rated for something like 50% duty cycle.

I know the Thomas compressors are continuous. They are oil-less so typically they are louder than oiled compressors, but they are solidly built unlike the box store variety. Rolair is another compressor brand that is solid. They make both oil and oil-less models.

I was in the same situation as your SIL except I don't have a hobby farm. Cleaning my chainsaws, pumping up tires and running a nail gun occasionally will be my uses. I found a decent price on a fairly new Thomas. The guy talked me out it because he thought I could do better with a lesser model. He pointed me to a new Makita 700. $159 delivered to my door, oil, 50% duty cycle, electric. Works great, been playing with it all week. Took it to a neighbors last night to help him put in a door and some other little things.

Good on you for trying to get the old part working. I'm just not sure how useful it will be to them if they can't move it and it takes up alot of room.

I do not know where to begin to look for parts and suspect there may not be any available. However you can usually make gaskets and some valves will interchange. The cylinders usually get rusty and ruin or break the rings. But rings can be had for almost anything. It may be worth opening but a quality pump can be had for 249 to 289 and cheap chinese for cheap.
Stay oil filled that stuff about continous duty oil less above is just that stuff. Only a linear in the small oil less is continous and they have a 1 to 2 year life expectancy.
It has been our obesrvation that if yoy need a pump and motor a complete unit is with in a few bucks of that cost and you do not have to mess with controls and belts.
Good luck,
