BX25 FEL loss of power...

Do both the lift and curl functions of the FEL seem weak?

Is the backhoe weak, too?

First thing I would try is disconnecting/reconnectiing all 4 of the quick couplers to the loader, to make sure everything is seated properly.

Check fluid level, when was the last maintenance done? Change hydro filter, like RCW said check the fittings. Check all the simple stuff first, thats where you will find most of the problems

Check the quick disconnects...if something blew in one of the cylinders stuff often gets stuck.

Invest about $30 for a pressure gauge and quick coupler fitting at hydraulics place.


If it will be more convenient to read the gauge, have a length of hydraulic hose between the gauge and quick coupler.

Remove a quick connect and plug in test gauge. Run at max rpm and send flow to gauge. Read gauge then stop flow to gauge.

You cannot trouble shoot without real numbers, i.e. psi

Do some research and find relief valve setting(s).

I suspect less than 2,000 psi but again check.

You also need to figure out hydraulic flow. Do you have power steering?
If yes does it have its own pump and reservoir or is it supplied by main pump and a priority valve?

Where does the 3 pt get its oil supply? From a power beyond port on FEL valve block?

These systems are more complicated than many people realize.
Study this hydraulic circuit diagram and you will see what i mean.


Don't go changing hoses and relief settings without a clear understanding and some coaching, Breaking very expensive parts happens in a instant and with no warning.
