Case 970 hydraulic pump

Pump is worn and pressure is low can the pump be rebuilt or have to buy new fresh oils and filter have seen pick up screen and it s clean pressure running just under 1500lbs at remotes @ 1700 rpm thanks for any advice
 

Is it better cold than hot, It could be a problem with the main relief. The only way to determine the condition of a pump, or hydraulic system for that matter is having the pump flo tested. The price of that pump is to much to just guess. In my opinion rebuilding one of those aluminum pumps is fruitless, if the bushings have wear the gears wear the internal parts of the pump and those clearances cannot be renewed without housings being replaced. Find out the condition of the pump and go from there.
