753 hydraulic oil question

[bobcat miner]

Trying to drain hydraulic system. I've had the motor carriers out. Is it safe to say all the hydraulic oil has drained out too? My oil seals failed and emptied the hydraulic oil into chain case. Just making sure I'm not missing anything before I add clean fluid.

Not sure if all the oil would have drained out, some yes, but there is always some in the motors,cylinders, pumps.
