    Matbro tr200 hydraulic pump

    The unit is made for the Matbro TR200 and the valve on the back makes it quite a one off hyd pump. If you want to replicate the hyd pump and a separate valve let me know as I have a data sheet on the pump, as for the cost of a complete pump I reckon you are looking at about £825.00.

    Hy reach head pump issue

    Firstly the current shaft seal is the wrong type. Your current shaft seal should be concave to accept a seal backup washer then a circlip.

    Post rammer hydraulic valve help

    If there is no info on the valve and you have removed the long plug and I presume replaced it with the "silver" one in the picture. Its time to replace the complete valve and install a more modern valve, your local hydraulic company should be able to help you out.

    Changing a kverneland wrapper to load sensing

    It looks like a Danfoss PVG32 valve which is good news. You may have a dual inlet cover on the valve which is easily converted to CCLS or you will have to replace the inlet section to CCLS. Part will be stamped on the inlet section near the gauge port and it usually starts 157B then 4 more...

    Ford 7810 power steering problem

    P = pressure port, so that's the inlet port to accept the flow from the pump. T = tank, so that's the port that returns the flow back to the hyd reservoir.

    Taking Spool out of hydraulic control block

    It's not a difficult job as long as the location of the spool valve makes it possible to remove the spool end cap. Finding a replacement spool will depend on the make of spool valve. Better pictures of the valve will help give a more positive response.
