That is thanks you all of you good folks on this site.
I put the back lift back together, then removed the vane pump. I disassembled the pump and checked it over for wear ect. It looked really good. I put it back on prefilling it with heavy lube ( similar to STP) Did the air in the dipstick hole trick. I left the outlet line off till I seen oil coming through the pump using the air pressure. I then buttoned eveything up and it worked instanly. It must have just lost prime someway, never happened in the 25 years I have owned it.
Thanks to all of you who helped me, you're the experts on these tractors for sure. Bill
