burnt up hydraulic pump

I just added a fast hitch to my 300 utility, i was running the tractor to get the air out of the lines and the pump made a terrible sound and the tractor stopped running, I just replaced a pump on my other 300 and i'm confident this one needs replaced now, after I install a new pump what should I do if anything differently to keep from burning another pump, I thinking my pump was on its way out and running it with the fast hitch was too much for it, the power steering worked but not like it should have, but not sure.
 
Not good if the engine stopped, may have broken drive gears on the front of the engine. Before getting another pump check for the pump being rotated.
 
You may have stripped the teeth off the timing gear. Bring No1 piston to TDC on the compression stroke then see where your rotor is pointing. Hal
 
The screen in the reservoir under the seat should have removed all particles big enough to lock a pump. However they can collapse and get ripped. If a chunk of rubber hose or other foreign material got into the intale side, there is a strong chance that the locked pump stripped the gears the others are discussing. Replace all fluid, remove the top of the res under the seat (sorry it is tough to do) and clean out the sludge and trash. Inspect all hoses for internal damage. Rinse the system with clean fluid. Remove the old pump and disassemble to see if it was jambed by something.
Then go from there. Jim
 
Sounds more like it seized. Maybe not, but screeching is always icky to deal with no matter what. Was it moving oil just prior to this episode or was there considerable air in the works? In other words, was any of the hydraulics trying to actually work?
