Rebuilding Hydraulic Pump

[Bernie Benz]

Hi Derek,

Most needed parts are available from your local O-ring or bearing supply
house.  But first, you must determine for sure exactly where the leak
is/are.  To do this, spray with gunk all around, under side too and hose
off.  Idle or drive a bit and look/feel for oil.  The shaft seal is an
unlikely leak source, inasmuch as it is under slightly negative pressure,
the reservoir level being a few inches lower.  Much more likely, one of the
cylinder head O-rings.  If you don't have a drag link socket, just use a
chisel to tap the head loose and use the largest flat blade that you have to
unscrew.  If a lower one you may have to remove the pump, but don't
disconnect the hoses, if possible.

If you can find the leak, I have the o-ring p/ns.
