I got water in my HY-Tran, now it look's like milk. What would be a good way to flush it out so I don't keep contaminating my fluid with milky oil. Thank's for any info. P.S. this is my first post.
 
Michael,I had a 340,wish I never got rid of it.I changed my oil several times,I think it was 3 locations and never got all of the milky oil out

Mike, I have the same tractor with the same issue. Keep pipe dope or teflon tape on the fill plug, but I think it's more condensation than water leaking in. I changed oil and filter in the system twice but it still gets milky. I guess if it bothers you change it. 10 gallons of hy-tran.
 
Michael D; welcome to the IH board, plenty of great folks and info. If you keep your cutey in out of the weather, that is the main thing. This board lost a great contributor last October, Hugh MacKay, and he said "...the best thing is to take them out and work the snot out of them." Enjoy your Farmall 340!
 
Probably cheaper to work it for a while so the water evaporates out while it is hot. Plowing all day got rid of it. Running the hydraulics under pressure will heat it up if you pinch them off a little.

I think the 340 is like many of the others and the rock shaft housiing under the seat is full of fluid. It has a drain tube that sticks up to keep it full. The bottom is probably full of sludge as well. It probably holds a couple gallons or more so you never can get it all out when you change it. My drain tube is welded but there is a long drain plug towards the front that can be pulled. Then it only keeps an inch or so in. But all your lines will still have milky fluid in them.

Between water leaking in around the shifter and condensation in the tranny, rear end, and rock shaft housing, it is near impossible to keep water out.
 
I'll echo what the others have already said. I've changed fluid 3 times in my 340 and it just gets milky. The condensation will get you quicker than anything. Work it hard once in a while if you can and try to keep it indoors.
