My hydraulic system on the dump trailer has Dextron II in it. NOW when I put a different pump on it ---it will be a used pump that was running regular hydraulic oil or trans/draulic type.
Question is, will the new used pump be ok running Dextron in it?
It would be hard to get all of the trailer system drained,--- then again maybe not bad. ---Main concern is cold weather use of the hoist. I use it quite a bit in the winter to haul manure home for the gardens and it does get cold on the road.
The trans/draulic type works o.k. in my tractors and thats what I kinda wanted to run.
If I disconnect the cylinders and push/pull them---most of the Dextron should be out. Will any remaining mix without problems?
I know some oils wont mix!--did that on an earthmover one time and had a wicked mess on my hands, so dont want a repeat of that ordeal! lol!
