I didn't need the "of course" as I know there is oil in the lines. but I don't believe the oil gets all the way to the automatic cut-off. The air in the line compresses and if the connections are all tight and not leaking, it would sure seem to me that the oil wouldn't get all the way to the cut-off. I would like to know what the compression ratio is in those oil lines as that would determine how far the oil rises. I plan to empty all oil from the lines before re-assembly and use a sealant on the threads to get it as air tight as possible and hopefully keep oil out of those diaphrams. If as some of you say that the oil does cause problems on the diaphrams, then John Deere engineers would not have designed the automatic cut-off so that it would allow oil to get to the diaphrams. All connections need to be air tight to prevent compression leakage or eventually the oil will get to the diaphrams.
