[quote="CVPost-Andy Wickiser"](quoted from post at 12:00:42 12/06/18) First, the 713 is a prior generation backhoe to a 3400, the "native"
backhoe for a 3400 would be a 750 or 753.
Anyway the hydraulic plumbing kind of depends on what loader/backhoe
combination you have. Below are two circuit diagrams for the 713,
one for a 19-97 or 19-105 loader with selector valve (no power
beyond), and one for the industrial setup, 712 loader with power
beyond on the loader valve.
I'm not sure what loader you have, but if it has power beyond you
would send the pump output to the loader valve and the on to the
backhoe similar to the second diagram. If it has a selector valve,
the setup would be similar to the first diagram. The third picture
is the selector valve on my tractor (19-97 loader and 713 backhoe).
Since you are "mixing and matching" you'll have to figure out what's
best for your situation.
Another thing, if you blew the lines off under a no-load situation
you may have deadheaded the pump somehow. Be careful, such a
situation can blow up the pump.
Thank you so much Andy! Can I ask what book those diagrams came out of? I bought a set of books for mine but misplaced them during my move. Those diagrams will at least allow me to see if it's plumbed correctly. Since it was a giant puzzle, I wouldn't make any bets
Mine does have a selector valve very similar to yours so it must not have power beyond. I know it is a 713 backhoe but I haven't been able to find a tag on the loader to be able to identify it. I've included a picture from one of my last posts if it means anything to you. Just looking at pictures online, it doesn't have the same bracing on top as a 19-97 or 19-105.
