JD 5205 hydraulics

Follow up on JD 5205-dropped oil, changed external filter and removed and cleaned internal screen. The screen was all clogged up. It runs like a new one!! FEL functions are quicker...it totally fixed the problem. I did check suction line and connections first, but all were tight. Thanks for some excellent "over the shoulder" help.
As for 450C loader, I had planned to pressure test pump and system relief valve, but pump is real loose in housing, so I think that is problem. Will check rest out first because pump is $1600+ new. I hope it is not relief valve--it is drott (has 4/1 bucket) and it appears parts may be hard to get--either entire valve or repair parts. I was told by JD dealer that Ford (now NH) had purchased drott from Case and had parts, but that may have been bad info--local NH dealer does not seem to know anything about that...!! So, the saga continues...Thanks guys!! :thumbsup:

If the pump shaft has play off axis then it is shot. How is the pump mounted? If it is via a coupling I would certainly consider an aftermarket pump for a whole lot less money. Same would be true for the valve with pr built in. I am a fan of Commercial Shearing pumps and motors and would suspect you can match one up very close to your pump. For an older piece of equipment I would look for a match at Surplus Hydraulics.
