I just picked up an m54 with a ENDT 673 Mack in it. It skips a little for the first minute or so then clears right up and runs great so im not too worried about it. Im thinking i may have a small bleed back issue but i haven't looked at it yet. The truck is overall in pretty good shape but is missing the bed and i would like to put a flatbed with a crane on it for moving PT 6x6s and other lumber. Does anyone know if the power steering pump is big enough to run a crane off of and what the pressures and GPM are? It looks fairly big but i also dont want to interfere with the power steering. If not what are my alternatives to run a pump off of other than a vbelt? Thanks!
