had some oil leakage around the slew ring area some time ago. it appeared after working for several hours, prior to this machine had stood idle for several months (strarted and moved a few times,no real work as such)
The leak is not apparent any more, slew ring area is dry.
Oil level in gearbox is ok.
I went to check the ring tub for grease recently( base of boom cylinders), and I can see a few mm of clean oil in there.
So is likey this is hydraulic from the motor, or from the reduction gearbox.
How do i drain the oil from the tub now, and which seal is the likely culprit
