milky hydraulic fluid in B6000

[tow2topgun]

I recently obtained a very used and abused B6000. Yesterday, I pressure washed it really well and began going over it. Noticed that the hydraulic fluid was creamy white which I understand means that it has had water in it for some time now. Well I went and got a 5 gal bucket of new fluid and drained the cream.after adding fresh, it is still creamy. I realize that all of the lines are still full of the contaminated fluid. My question is how do I go about completely flushing the system to get the emulsified fluid out. Is a drain,fill, operate the system, drain, fill.... And so on until its clean or can I disconnect a hose and pump it all out? Thanks in advance and I have PLENTY of more needed advice coming at yall!

I would use the drain, fill, run - repeat methed. Trying to pump it out risks the pump.

Ok, would this milky fluid cause my hydraulics to be slow? The front scrape blade is usually very slow to go up and down but the rear tiller attachment will come up very fast but takes forever to go down. The line for my rear hydraulic control has a pretty good leak. Would this be the cause? Thanks for the quick response.

Tow - My B6100 was the same way (milky). I changed the trans oil but replaced with wht my old manual recommends (SAE 80W Gear Oil) Once it warms up the hydraulics are much better. I plan on changing again to a lighter weight universal tractor oil to see if thinner weight helps even more. Here in Va. we've had some cold weeks and the hydraulic on my front blade was slow as that gear oil is so thick (I guess).

Anyway - what kind of oil did you use?

Do you have the "dozer" blade on your B6000?

Thanks. FF

Topgun, I recently changed out my 80w gear oil for a Universal trans hydro fluid. It was pretty cold out when I did it so I ran the tractor for a while to help warm the oil. When I drained it it was very milky looking. I couldn't understand how water could enter the system so i looked closer and realized that it wasn't water but bubbles, it was foam . After sitting in a bucket overnight they were gone. I guess what I'm saying is you could save yourself some grief if turns out to be air in the oil . That 80w is no good with a loader in cold weather. My loader is much quicker now when cold.
