Running fel from b/h pto pump

[Timothy]

I have been having problems with Jinma 354 ZL 30 fel , blown tractor hydraulic pump , I have always had concerns as oil gets hot . My solution is to use LiTW bachhoe pump to power both backhoe and fel , the backhoe oiltank is 22 litres as apposed to the tractor's 8.8 lts. so oilshould stay cooler . Have ordered after market loader valve from Ranchhand , this valve has power beyond so I propose to plumb pto pump to the fel valve , power beyond to backhoe (7600)and t return for fel to backhoe return just before the filter that goes to tank . Am I correct in my plumbing ? This set up would allow me to use the tractor hydraulic pump as bach up in case of problems . Timothy
