After having removed all hydraulic oil from the tractor, the loader cylinders(4), and all lines; and replacing the hydraulic oil filter and cleaning the s.s. micro-screen and refilling the system with new hydraulic oil, working all loader controls back and forth for 40 minutes I cannot seem to get all of the air out of the system, for the loader does not work fully, nor consistently, and sometimes not at all. )The rear rocker arm lift works properly.)
I replaced the oil for it was contaminated with water, getting in at the shifter boot, which I have replaced, along with the oil fill o-ring.
While working the loader controls, I have kept adding oil to now the point of overflow (out the shifter), so I know I have added more than enough oil for the tractor and loader capacities (almost 14.5 gallons at this point).
I think I need advice on how to "bleed" the final air out of the loader system ? (I have been told that is not necessary, but I m now not so sure that is true.)
During the filing and working of the loader controls have also replaced the oil filter twice, and cleaned the ss micro-screen three times, thinking that minor miscellaneous contaminated oil (that was not evacuated) might be clogging the filters.
How would You suggest I bleed the air ? (partially loosen two lines at the throw ? or pull side ? of a pair of the cylinders (curl or lift cylinders ? )

The golden corn ripens well and early, the stoking, stacking,.... the drawing in with the tractors and trailers and a few buck rakes thrown in, and possibly a heavy horse. It would be a great day for the collies and the terrier dogs, rats and mice would be at the bottom of the stacks so the dogs, would have a busy time hunting and killing, all the corn was gathered and ricked in what we c
