Was taking advantage of the frost to get some chisel plowing done and ran into an issue. Got done with the first field and jumped out to set my transport locks when I got a whiff of hydraulic oil. Started to investigate and found oil coming out of the dip stick tube on the three speed. So ran it back to the house and drained the oil back down to the correct level and ended up with probably the better part of 2 quarts out of it. I can?t recall having to add any oil to it recently so I have no clue where it came from. Now for the other half of the story. When I drained the oil it was pretty hot. Wasn?t boiling but it was warmer than I would expect it to be but at first I chalked it up to the unit being over full. So took off and chiseled another 5 acre piece and checked the level again when I finished up. It had been coming out of the breather again although not nearly as bad as it had been the first time. Looked in the dip stick tube with a flashlight and could see the oil at the very bottom edge of the tube. The oil was warm again so I didn?t bother reading the dipstick. I?ll check it tomorrow once the oil has gone cold. So my question is, is it possible for oil from the differential housing to get into the three speed? That?s the only thing I can come up with for the source of the extra oil. The three speed was never an issue before I had everything apart to do the clutch this last summer and everything went back together alright. It still shifts good and hard in all three gears and doesn?t seem to slip. So I need to find the source of this oil and the source of the excessive heat.
