Hydraulic resevoir tank has emptied with no signs of oil on the ground. Opened up inspection plate on front of table and oil is inside turn table. No visible signs of leak. Checked the dipstock on swing motor and it seems normal. ANY IDEA WHERE LEAK BE COMING FROM OR WHERE IT COULD BE BYPASSING?
More than likely your rotary manifold which sits right in front of the swing motor and has the four travel hoses going to it. The top seal goes out and leaks into the turn table area. But there's not enough room in there for the entire contents of the hydraulic tank there would be some leaks around the swing bearing and possibly underneath by the bottom side of the rotary.
Your talking about a crapload of oil if your tank is empty. I don't think there is anywhere on the machine that would hide that much oil.
Crynbroke, you say empty, do you mean nothing showing on the sight glass or take the lid of the the top and it's empty?
Nothing showing on sight glass
There is some seapage and leaky around rotary
