Ford 1320 Slipping Hydro

  Is there a bypass in the hydro system that can either be adjusted or shimmed?  My tractor seems to go to bypass rather quickly when pushing the hydro hard.  I have a new hydro filter and hydralic filter on the tractor.  I wanted to see if I could adjust the bypass before I assume the hydro is bad.

Thanks, Mike 

 before we dig too far into this, can you give more info about what conditions your noticing this in? The relief is there for a reason, if your operating in high range and mashing the pedal to the floor than the hydro should be going into relief. If your in a lower range and pushing gently and hitting relief than we've got a problem.
