UNHOOK HYD. HOSE AT THE CYL. SEE IF YOU ARE GETTING OIL THERE . IF IT IS AN OLD HOSE IT COULD BE COLAPSING ON THE INSIDE.

Does the pump quit pumping or do you hear the pump trying to lift when it stops lifting? MACK

Where are you checking the oil? Should be at the dipstick on left side of tourque housing across from hyd. pump. that is the fill pipe also. and as Mack asked can you here pump trying to raise lift?

I had the same thing happen on my CA. One of the pump plungers was stuck in the compressed position.

Just for grins,screw the thumb screw down on frt of pump all the way in then back out and see what happens.It'll force the valves to move.Could have f/m sticking valves.
