It may not be that easy to find a good used pump but it is a Commercial Shearing pump which is good news if you shop for a new one. If you find the numbers on it you can search availability online. It's two stage, the main stage puts out 25 GPM and the smaller 15 GPM. If you come across any Case 680 E's or G's they may have the same main hyd. pump I don't have any details on the power steering pump.

What is happening with the pump - are the wear plates on sides of gears worn to allow bypass or other problems ?
You might be able to rebuild your pump .
Had a pump on a NH 785 skid loader that went bad -new from NH was a arm and leg price but found a Cessna pump new that matched - except input shaft was keyway rather than splined - switched input shafts (worked straight across) new pump / old shaft - 1/4 the price

You wouldn't want to grind on wear plates. they are soft metal,sometimes bronze

I know when I saw my 816 pump taken apart the surfaces looked like sand or gravel had gone through the pump and yet I was told that's what general wear looks like after lots of hours on the machine. If the rest of your machine is in pretty good shape it should be worthy of a brand new pump, you'll probably get one for maybe around $1000. You may possibly find a used one but if it's simply a "take off" it's only a guess what shape it would be in as well. A new 40 GPM pump really makes that machine move and lots of power to boot. My 816 would pick up the front end of my gravel truck off the ground using the front cutting edge held flat, that's 11000 lbs.
