[Farmall] dirt in hydraulic unit

i wonder if it is possible to flush out with solvent
not by using the hydraulics, just in the top and out
the drain. the dirt is laying in the bottom as viewed
through the drain and is at least 1/8" deep.
everything works, both sides, one side will creep down
and come back up to original position. i dont want to
dive into this in a major way at this point.

what do you think? thanks, Walt

If the boots are really old they will be leather, and tied in place with 
wire. The new ones are rubber and I think the last 4 pc set we put on cost 
close to $100. More than likely you'll need to replace the O-rings on the 
shafts behind those really greasy, nasty, dirt filled boots ( in other words 
you may want to give it a good washing before you tear into it). I doubt the 
boots had anything to do with the fluid being dirty. If you don't have a 
leak, I'd leave them alone. If you do have to go into it, you may need some 
patience, good penetrating oil, and a little luck to get out the cotter pins 
and set screws holding the contol linkages in place.

The only way I can think of  that dirt got in the system was somebody being 
careless at some point when adding or changing fluid. If you decide to just 
drain the fluid, I think you need the left rear of the tractor to be at the 
lowest point for all the sludge to drain out. Be sure to pull out the filter 
and wash it off.
