m&mv80 Posted February 7, 2008 Share Posted February 7, 2008 This is my first post so first off hi to everyone, I've been browsing the forum for ages and thought it was about time to join in, so here goes, I have a landrover 90 v8 and fitted a milemarker winch about a year ago running on a dedicated zf 74 pump, this works fine but was extremely slow as im sure most of you are aware. Basically I have now fitted a pto pump on the transfer box running through a manual spool valve and ocv then to the motor on the winch, I have just finished the plumbing tonight and tried it for the first time, Well it has certainly sped things up a bit, but I was suprised to see what pressure the system was running at off load, In 4th gear at about 1200rpm the guage was showing around 1100psi, is this correct?? It seems very high to me but im not sure if the ocv would cause this or if I need to adjust anything to reduce this off load pressure, I was hoping that the guage was going to give me some idea of load when using the winch in anger but if its running that high off load then its not going to tell me very much at all, also whats the best way of setting the relief valve?. I have heard by locking the winch mechanicaly by selecting both gears together you can bend something??, is this true and should i just rig up between to big trees or is it ok to do this? I know a few of you guys on here are pretty clued up on hydro set ups so im hoping I'll get some answers, I'm an engineer myself but have never been involved in hydraulics so im on a bit of a learning curve here, thanks in advance for your replys, Cheers Martin Quote Link to comment Share on other sites More sharing options...
