TX 2160F, with front loader and backhoe, long term project

[chrismac]

I did the same thing on my Rexroth valve for my loader valve. While it was drilled and tapped for the Carry over or Power beyond port and had just a plug blocking the port, I still had to block the internal passage to the tank port.

You may want to check that out on that valve to see if that's your issue.

Thanks I will do and report back, if I block the out port, I gather I am then forcing oil down the HPCO as thats the only route out, will that affect anything else.

Your correct, when I disconnect the return line to the tank, the 3 pt linkage works as it should, strangely the loader also seems to work fine..... cant make any sense of that as I thought the return line would have been for the oil being discharged in the opposite direction of the ram movement, mind you I can leave it plumbed in and just disconnect when I am using the 3pt linkage as its on a quick release coupling.

Got this issue fixed tonight the o-ring on the HPCO adaptor had been nipped during assembly and that was the leak path to the return side. New o-ring fitted and my 3 pt linkage is working as it should.

That will do it. I figured it was so something along those lines.

Being that you had still some pressure at the 3pt, it has to be a very small internal leak.
