I have to change the common sump hydraulic/trans/diff oil in my tractor. I have confirmed there is some unknown quantity of water in it. Right now the loader is installed, but I will be removing it very soon for field work and it probably won't go back on until fall unless a special need arises.
Question: Should I remove the loader first and then drain the oil, or should I first contract the cylinders all the way and drain with the loader on? Of course there would still be oil remaining on the other side of the double acting cylinders. When the loader is removed and on the parking stands the cylinders are not usually fully retracted.
The thing is I would like to have the least contamination of the new oil as possible from the oil in the loader cylinders going back into the system. What is the best way to do this? The loader is a NH 820TL.
