rsb502 Posted February 18, 2013 Share Posted February 18, 2013 What's the issue, I've removed hydraulic pumps in 3-4 pieces from rr equipment.

refusegetter Posted February 18, 2013 Author Share Posted February 18, 2013 The issue at hand is finding one that works. Today is one of those half-assed holidays, local distributor is closed.

rsb502 Posted February 18, 2013 Share Posted February 18, 2013 We had a bunch of gear pump failures about a year ago, basically you opened the case and drained the metallic oil sludge, no real parts to speak of left just little metal flakes.

rsb502 Posted February 19, 2013 Share Posted February 19, 2013 Oilgear was the pump issue with us we got a bunch of rexroth replacement stuff, not sure about some of those rexroth valves they look a little sketchy to me.

Freightrain Posted February 19, 2013 Share Posted February 19, 2013 Hopefully the Rexroth hydraulic stuff isn't as pricey as their servo drive stuff!! We have a CNC full of Rexroth stuff and WOW....they are proud of that stuff when it comes time to fix them. Quote Larry 1959 B61 Liv'n Large......................

rsb502 Posted February 19, 2013 Share Posted February 19, 2013 No its expensive as hell and all our gradalls are electronically controlled rexroth valving, not real easy to diagnose.
