Ford New Holland 1920 slush in my Hydraulics

[Atvjoe]

Hello to all to keep it short I purchase a tractor a while ago, that the hydraulics did not work, do to contamination of water so I cleaned the inside of trans with a wet Vac and a lot of rags, after changing the filter and all the oil it worked great for about 5 or 7 hours then the filter got clogged again so I replaced it so I can finish the job I was doing, it got clogged again so fast I could even lift the box blade,so I parked it for a few months. Does anyone one have a good way of getting in the tight spots where the water slim is hiding? I was about to remove all the transmission covers and try the wet vac again. Please let me know any ideas you guys got. Thank you all.

A few gallons of diesel in the trans case and sloush it around rock the tractor back and forth,
then drain.
Refill with cheap (TSC) hydraulic/transmission oil, remove the lines at your loader cylinders, compress the cylinders
to remove all possible fluidwith some helpers bump the hydraulic controls to push fresh oil out the hoses into a couple of 5 gallon buckets.
Hang on to the hoses and the buckets well as they will try and fly wild. While flushing keep adding fluid.
When well flushed top off and operate all hydraulics for a while then drain again, then either repeat or if all looks good refill with good quality tractor transmission/hydraulic fluid.

Update I warmed up the oil by running the Tractor for a few minutes, then I drained it all and used a shop vac with small hoses connected to the end so it could reach in to tight spots. I also used Long Flute brushes and small ones from work to rub the case. Then I poured 8 Gallons of Diesel like you Said Louny and scrubbed away all the slim. Then Drained, then repeated with more diesel. I drained it and it looks AWESOME!!!!!. Oh I also removed the filter and Steel Lines that go to the filter and the pump. They also had Water/slim inside. I poured fresh Hydraulic oil and new filter. The only thing I have not done is the front loader, but its disconnected Im going to open all the lines and cylinders and drain it out with air, and After I purchase more fluid I with flush it like you said with the lines not connected and hold tight. Thank you for all your Help.. here are the pictures I took after the wash.. *** I found a cap or Freeze plug on transmission lid with a cut that i think was funneling in water, next to steering stem. see pictures
