Re: C-Drive Oil drain - Alternative
toggle quoted messageShow quoted text
Hello Ruedi, I did have some slight milky color just after changing my seals a previous time. I don't think they seated properly right away. First I drained and cleaned our the reservoir well. Then filled it with clean oil. Then I sucked about a liter of the bad oil that comes off of the small "return" line and attaches to the top of the reservoir. I did this twice and that removed some of the milky oil (can't be much as there are 8+ liters in the system).
I can tell you that the water did settle out of what I removed after a few days. I repeated this twice when the drive was heated up and the oil was mixed up. Then after that it remained clear. I was using the boat regularly during the next 6 months living aboard in the Caribbean. At the end of the season when I pulled the boat and drained the c-drive only the first liter or so out of the bottom of the drive appeared to have some residual water. The seals appeared to be in perfect condition.
I think in my case I only had a small initial contamination and once the seals seated well then there was no subsequent leaking.
I wish someone could provide a clear explanation of how the oil circulates? I was able to watch as the drive heated up with use that there was milky oil coming in the return line at the top of the reservoir. There is also a filter screen in the middle of the reservoir that appears to trap some of the water that settles out. For something so important and so discussed I've not seen a good explanation of that.
Thanks and regards, Daniel and Lori Carlson on sv BeBe, SM #387
