   Well, had another close call with my D14 PS and its time to fix it before that sob breaks my arm,,,,,I had posted a couple of years ago and Dr Allis mentioned the seal in the pump had failed and was allowing the PS fluid to migrate into the engine crank case. I've had to drain all the PS fluid out of oil pan several times and ain;t doint that chit no more,,,!!
 Does anyone have any dwgs of the parts and pieces to the PS,,?
  Also,  who to buy the parts from??
 Thanks for any help on this,,,ClapClapClap

Desert Joe:

The power steering units equipped in the Chalmers D14 were built by J.S. Barnes Company - find additional support here:

Those old AC D14 Henry built backhoes are well built units!
