Ya, a guage wouldn't hurt to verify what you already know, the pump is
wore out. beware old Case parts must have thick gold plating on them,
judging by what they ask for them. Repairing an old hoe can be a money
pit, BTDT. it might be time to send this one on down the road and shop
for another. that's what I'm doing right now, looking for a ford 555

I was talking to a friend of mine a few minutes ago and he said
grinding the end plates flat works pretty well to raise the pressure
some. But there will also be some wear around the periphery of the
gears that I can't fix. If I can figure out which pump the thing uses
I'm hoping to find one surplus. As far as the hoe being a money pit I
really haven't had to spend too much on it beyond the 5 grand I paid
for it. So three hundred to fix the hydraulics is probably OK. I
bought it to install my own septic system and saved about 9 grand over
the lowest bid I got for installing one. The County said it was one of
the best installations they had seen, they were actually talking about
me at the health dept. I had never even sat on a backhoe before I
bought it so that's why I don't know if it is closed or open center.
