Changing Hydraulic Oil in BX2200

[kpbeddin]

I will be changing the Super UDT for the 300 hr service. Now that I have a FEL installed, I was wondering if I will need to bleed the hydraulic system afterwards. Any pointers would be appreciated.
Thanks

Hey neighbor!

I think you can just fill it up and then start it. It should pump the fluid around and the be ready to go. At least thats what I did on my 2230. (before I traded it last week.... )

Ok, thanks for the information neighbor. I could not find anything specific to this in the owner'a manual and wanted to be sure I wasn't overlooking something.

the bx's is self bleeding. you just need to cycle the ram fully a few times and all air will be purged.

Can you expand or define those terms, please? The BX is self bleeding. What does that mean? Is it something we need to do at routine service times?

And the other statement leaves me in the dark, too.

Thanks.

Self-bleeding means the tractor's hydraulic system has a port which will allow trapped air to escape -- on its own, nothing you need to do.

Cycle the ram-- after refilling, operate the controls for the front end loader and/or backhoe, if you have one, to their full extent a few times. "Ram" is another word for the hydraulic piston. As the piston goes in & out, any trapped air will migrate to the bleed port.

You may have to let the tractor run for several minutes; I did on my GC2310. After an initial panic attack --nothing moved, at least not much-- I just let the thing run for about 10 minutes. It took that long, on my tractor, for the fluid to be circulated all around and for all air to leave. After that, everything was OK.

thank you irvingj- thats correct however i always thought that the air gets released at the oil fill area in back of tractor on the BX's . I am not sure about that, need someone to confirm as things can vary from brand to brand. Just keep an eye on the fluid level and make sure its always full. if it gets too low, it could start sucking air and cause the oil to "foam" and have air in system, worse then having simple air in the hydraulics after a change.

As I learned from an earlier post I had...the system has a vent hole and purges air when it needs to (thus the smell of hydraulic oil when operating). Therefore any air in the lines will make its way out. Yes, check the level after several cycles of the FEL and/BH, mine required addition after I cycled mine.

Radioman-- yep. After I posted that, I was thinking that's probably where the air "gets out." Guess I had a pic of a water system in my head at the time!:confused2:
