Prentice 410D Loader - Hydro Pump Pressures

[hdpirtle]

I have a Prentice 410D loader and it has become weak over the years doing pull through delimbing.  I want to do a hydro pressure test on each of the 3 pumps but not sure what the pressures should be.  Anyone have experience with this loader that can give me an idea of what a good reading should be?

thanks.
