270 international hydraulics problem

[IH270A]

OK !! here is the problem , I bought this old machine not running , and have
been slowly putting her back together .. first problem was injector pump, some
body had removed the pump , lines, and injectors .. but I repaired all of that
and the engine runs great, so I changed all the filters and fluids , but the hoe
is still weak .. I took the pump apart ( eaton .. variable displacement ) it was
very clean ,, so I removed valve body ( cesna 33100 ) replaced all the o rings,
but I could tell all of the relief valves had been removed before , so I think that
they could be in the wrong ports .. does anyone have a diagram of which psi
valve goes into which port .. also can somebody tell me which line would go
from the rear valve body up to the valve for the front bucket .. I have on my
valve body inlet .. out ... PSI bypass ... and that is the one leading to the
front valve .. is this right ?? .. the line comming from the " out " fitting is
going to the main hyd filter ...

thanks

I find useful information in the Case on-line parts book, you might find a parts manual on ebay.

OK !! I think I have it figured it was a bad seat on a relief valve ..
