Oh, no, it is piped from the out on the loader spool to the in on the backhoe. I checked, it is the 712 fordson loader and 713 backhoe. The spool valve is original. Can't find the relief valve replacement anywhere online anyway. It is not adjustable. I'm guessing if I can't find it anywhere I have t...

Thanks Dave! I don't know the history on the machine, but it appears to be a factory made and possibly installed 713 backhoe and I don't know what # loader. PO had redone all, almost all, of the hydraulic hoses as well as rebuilding the spool valve for the backhoe. The left stabilizer won't stay up,...

On the left hand side of the backhoe (from sitting in the seat), there is a large locknut (over an inch). This has a allen headed threaded rod. Is this where I will find the pressure relief valve? Is it one valve for the whole backhoe attachment, or is there a valve for every function. I don't have ...

I'm new to this site, owning a tractor and working on hydraulic systems. I just picked up a super major with a 713 backhoe on it, and I'm of the opinion that it has issues with the pressure relief adjustment. The loader works like a charm, and shares the same pump. All the hydraulic lines are new, a...
