Nice work Mike... see how you go with the power steering lines, if you notice slow response then you can hard pipe. If still no good, we can come up with something. Funny, the other day, we were commissioning a new machine and we chopped the pilot hydraulic lines from 14m to 7m as the response was terrible.
Might be an obvious one too, bleed out all air!
Is the Pootrol alternator higher amps?
