So I decided to change the gear oil in the rescue 212 today as part of my “get it ready to sell” process. I think I made a good choice…
Yes definitely better than not doing anything. However, I would at least put some light weight oil in there and try to flush the "crap" out. If it is runable, I would put it up on stands, start the engine, and put it thru the gears just to circulate the lubricant. Then drain.Not this time Ken. I wondered if people would have recommended that. I don’t have anything diesel powered so that would have taken more planning than I did. Probably will hold onto the gear oil jugs from this change to bring some home from work for the next one.
Even without a flush I figure this one is going to be light years ahead of where it was. Hopefully it will serve its new owner well.
WoW! Definitely good that you changed the oil. It's amazing how some previous owners will let it go so long to get into this condition. I'm wondering if water had gotten into it over a long period of time to create this goo, just a guess. A diesel fuel flush or some other type of flush does sound like a real good idea. Maybe Sea Foam would also help but check with a few others about any recommendation on that. I'm sure you've extended the service life of the trans by having caught this when you did. Even after doing a flush and adding fresh oil it might be good too to run it for a period of time and change the oil a second time.
