I came across 4 used hydraulic pumps. Not sure what to do with them yet, but here's a link to a description of them:

Parker - H39AA2C

From the specs, it looks like they'll be good to put on the shelf to use for something!

It doesn't mention the displacement. With out that it's hard to know how well the pump will work for your application.

A document I found says 3.93 GPM per 1000 rpm.

At the moment, the only thing I could even imagine building would be a log splitter. I'd need to do some research to see what pump capacity that would take. Any idea?

That pump would work great for a front end loader on a garden tractor. You'd want to pulley it for around 8gpm, or 2,000rpm max.

Do you think the sleeve bearing will handle the side pull of the belt?

The one I've been using a few years now on my FEL is sleeved and still going strong. I am using a 5/8" belt & don't have to have it very tight though.

That's great to here.
Now I can use one of the many pumps I've collected over the years.

And if the pump shaft is long enough, or you can add a shaft extension, then you could add a pillar block bearing out there for even more security. I just run my belt barely snug. It will almost slip under a heavy load, but no high side load on the shaft this way.

I never even thought about side loads on a pump but I think if it was concern maybe a double pulley or how about a belt tensioner that's close to the pump pulley so more of the belt makes surface contact with the pump pulley .
