I'm changing the oil in a d5b Cat dozer drive train. It got buried, and took on quite a it of water. I have changed the oil and filters once, andd cleaned the filter housing and strainer housing and took the back plate off the reservoir. The oil is still milky. Before I do this all again, what can I do different the second time? Can I flush the system some way?
For the second round, I put the blade on some blocks and lowered it all the way down. This tilted the machine back so the tranny drained (at least drained more) to the reservoir.
I'm going to let it drain for a few days in the tilted back position before I fill it with oil again.
