should i clean my bearings with it or not
Hydraulic oil is not designed for cleaning, nor is any oil. Use a solvent like denatured alcohol. Lube the bearings with a skateboard bearing lube. The base for hydraulic oil is mineral oil. It evaporates too quickly and the additives can leave a residue that attract dirt and may damage the crown and shield in the bearings and the wheels.
I wouldn't. It shouldn't matter if your bearings, unless you pressed them wrong, but if I were too, I wouldn't
It is used in the tractors hydraulic system in the front and rear end loaders for lifting things like Hay Bales etc EDIT-If there is no hydraulic oil in the hydraulic system then the hydraulic system won't work because there is no pressure being created to generate power to the auxilliary items.The tractors engine will still run because it doesnt use hydraulic oil.
