Need for free oil return line on 6045?

[roddarn]

Hi everyone.
Sorry if this has been covered before but I couldn't find an answer in previous topics.
I installed the larger 32 l/m pump on my 6045 a while back and the hydraulic 3 point arms got much faster than before. However when I connect my forest crane through the outer circuit, it isn't much faster than it used to be. Does anyone have an idea if I need to install a free return line for the oil instead of letting the return go through the spool valve on the tractor in order to increase oil flow in outer circuit? If so, where do I attach it?

6045 should have a free Return an inlet marked 0 the others for the spool valve are marked 1 and 2. if you have to put it in Renze will be the man to tell you exactly where it goes.

A free return is for leak oil from a hydro motor. It has absolutely no backpressure because it goes straight back to the rear end instead of via the return filter.

Your crane wont go any faster when the return is direct to the rear end instead of via the filter. Most likely the swing cylinder of your forest crane is flow restricted anyway.
