SW OH | Most of it, yes, but it will take maybe a year. If your using UTHF which you should be, boiling the water off is the only way to remove all of it. The problem with draining and refilling with new oil is removing every plug will only drain about 2/3s of the oil. The other 1/3 still has water in it.
We had a CAT 320 at work with so much water in the hydraulic oil at 20 degrees it turned to a slushie and would not function. Every line was removed and foam balled, every cylinder, motor, pump and valve was rebuilt, and the tank swiffered clean. Even after all that the new oil still had traces of water. Water absorbing filters on a kidney loop pump finally cleaned up the rest. 2 guys worked on this for 3 weeks. It ran another 6,000 hours before being sold with no further problems.
The higher pressure the system operates, the more damage water does than dirt.

Will water and hydraulic oil separate if sitting for a while?
