Recently replace hoses for front loader,, now have no hydraulics in the backhoe,hoy do you bleed system.
The system bleeds itself. That is not your problem.

You probably swapped the tank and power beyond connections in the process of replacing the hoses.

Not an expert, like the rest of the folks here, but did you connect the the hoses in the correct order? I only know the 520 and 520s and have never had a backhoe attachment but Dan is correct the system self bleeds (unless you have a cab loader with heat then you have to pump water up and thumb it closed while connecting! But that is not hydraulic system at all) you are pulling on the auto throttle I assume(

I suspect one of the couplers is not completely hooked up. Remove and reinstall.

Will try new filter
Its not the fiiter and randomly swapping connections is not going to find your problem. Stop and analyze the symptoms.

if the backhoe is not working and the loader will not raise the problem is most likely a blockage in the power beyond circuit. The power beyond hose on the loader valve or the backhoe return to tractor may not be properly connected. Did you replace any hoses or mess with the connections on the backhoe or was everything done at the loader?

I have seen new hoses that are blocked because of not properly preparing the hose and fitting when assembling. Remove the hoses and blow compressed air through them to check for obstruction. Please note to blow air from both directions because sometimes a ‘flap’ of neoprene will act just like a check valve

Along that same line...........did the hoses come with FME (foreign material exclusion) plugs? Were they all removed before installation?
