MF 1040 Hydraulics/Loader Issue

[davidshobson]

I have a 1985 MF 1040 with loader. I replaced four lines on the loader after blowing one. I also replaced the hydraulic filter. Now the loader will only go up and the curl action wont work at all. I cracked several joints in the system looking for air, but found only oil. I replaced the loader valve a year ago and had a similar issue, but it eventually worked out. I can't work this out, because I can't exercise the system as it only goes up.

Any ideas?

Thanks in advance

Did you replace all line at one or did you replace them one at a time?
I guess all at one and you crossed a line.
I would disconnect or crack each line and work your valve to check if the fluid flows or leaks where it should.

Using a loader valve with PB, you should have 7 hoses.

IN hose

OUT/TANK hose

PB OUT

4 cyl hoses

Pump flow goes to IN port.

PB hose goes downstream to the next valve.

Cyl hose conect to the appropriate port on the cyl.

OUT port goes to the OUT/RETURN line.
