Hi Vick, this is flh77hd1 from WV, i spoke to on the phone a few days ago about my B8200 FEL not working and wondering if it was the Hydraulic pump. I took the pump off like you said. The 3/4" tab is on the pump and it looks clean with no visually damage on it or the gear pump. All is clean. I placed my thumb on the (suction) inlet and finger on the return (outlet) then i turn the tab with my other hand and you could feel the suction on my thumb. I crank the motor on the tractor and could see the slot on the gear where the pump tab inserts when the pump is mounted and it turns with the motor cranking.Blew air thru filter screen also.Question: how do i prime the pump and what i have done so far does that indicate that the pump works?. I don't want to start the tractor up without knowing if or how to prime the pump.I know you get a lot of questions and i'm sorry to put more on you but i'm dead in the water and on my last nerve. Any help would be greatly appreciated.
