The hydraulic axial motor that turns the turntable is leaking lubricant...

Is their a leak or is it a release valve?

So their was absolutely no lubricant in the hydraulic motor so we filled it back up again and ran right through and out the bottom. Is their a release valve that lets all the lubricant out or something? Its a Daewoo Solar 130 LC-V.

The motor that rotates the turntable does not hold lubricant we put it in the day before and by the next day it was empty

If it's like all of my larger excavators, the hydraulic "swing" motor rests on top of a gearbox. The gearbox has it's own oil, and is typically equipped with a dipstick in the fill tube to check the level. If that dipstick fill tube is on the gearbox in question, then the output shaft seal is leaking. Failed seal, or damaged pinion shaft and bearing are the source of the leak.

You should soon start seeing oil coming out between the parts of the slewing bearing if the swing box is leaking that much. You can also remove the cover that is somewhere under the boom or nearby to view the ring gear compartment. The lost oil will likely all be in there.

Well the problem was resolved and it was actually a very easy fix... The petcock was open and the lubricant was just running through. Thanks for you help!
