Need to get air out of the hydraulics

jester7891 · Mar 15, 2011

I have a Kubota B 7610, approximately 4 years old - not a novice but clearly not an expert so you need to speak simply. I just bought a Daunuser log splitter that needed new hoses. I was able to go to my Kubota store and get the new hoses to fit. I previously had someone cut the hydraulics in the back of my tractor so that I could hook up a backhoe attachment - works really well.

This is my problem. I emptied out the old hydraulic fluid from the log splitter as much as possible. The new hoses obviously do not have any hydraulic fluid in them. How do I get the hydraulic fluid throughout the whole system so that I don't have any air? Thanks, John

Just cycle the hydraulics a half dozen times or so. This will remove all but a small amount of air. After that, the air will work itself out of the system as you use it. Top off the hydraulic fluid as needed.

You should be able to purge the system of air by cycling the cylinders. Keep an eye on the oil level as air is displaced you may need to add some oil.

Just like the previous two guys said run it through a few cycles. Make sure it is topped off. From what previous readings I have had here make sure the hoses are as clean as possible before installation. It might be too late for you to do that now. While you are doing all of that fix it stuff have you changed the filter lately?
