Help Aj Poclain 600

[Emu]

Aj Iv"e been told that you were familiar with Poclain equipment as well as everything else, I got an 1983 Poclain 600CK backhoe that I have been using quarrying limestone,you may say that it is time I changed it but there is no other excavator of that weight and power with the same breakout force without going several sizes up,lately the power has dropped,first I got a mechanic to reset the pressures but that was a bad move it worse now than before,even though this guy is good on other equipment he does not have experience of the vidro dyne multiflow system on the 600 can you help,all functions are working as they should but are down on power,I would appreciate any advice you could give me,would you by any chance have a manual I could buy from you.

Yes I am familiar with Poclain equipment from the start to their takeover by Case,there were a lot of them in my catchment area, I would say that your problem is the main regulator valve,I will email you the procedure on how to remove it and what to look for with the pressure setting procedure as well as there is a special sequence for the setting,about the manual to my knowledge there was never any manuals for any Poclain machine only the operators handbook but some could have been printed by someone else that I may not know about.
