Looking for a direction to go with on this one. Unfortunately I do not have a S/N on hand at the moment.
Hydraulics are slow, story I got was it was sent out for servicing a while back and when returned the hydraulics were slow, I'd guess about half the speed they should be.
This machine has a Rexroth variable displacement piston pump and relief is set at spec (approx 3,480 PSI). I'm suspecting the pump isn't upstroking as much as it should. The hydraulics don't feel weak, just slow. I have access to a shop manual but it is very poorly written. I can't see it being a pump failure being that it happened so quickly and has not degraded any further over the last few months. Is there an adjustment someone could have monkeyed around with that would have affected the pump upstroke?
