Ok,

This is very frustrating and I know its going to be hard for the Kubota dealer to troubleshoot because he is not going to use the BX for more than an hour to wait for the sound to appear. So where do I go from here, I know its not normal, it was never there before.

Any more ideas would be great.

I would record it for them.

Please keep us posted. I am having the same issue with my BX25 except it's out of warranty so my dealer won't do anything but charge me. Thank you.

Well no changes with my issue but one thing I would like to know. Is there any adjustment with the bypass valve on the BX25. If so could someone tell me where it is. My Kubota dealer mechanic mentioned it could be an adjustment but never offered anything other than that.

I dont have the maintenance manual so I cant look it up. Any help would be good.

Thanks

Try this thread where Achinbac shimmed his relief valve for more PSI in his BX.

Set mine to specs...does NOT make a difference.

So in the picture with the red arrow showing the location he said that the lower port/plug is where the valve is located but in the next picture there is two plugs layed out. The other longer one looks like the upper port/plug, what is this portion called? There is only one bypass valve, correct?

Just a follow up. I had my bx25 at the dealer today for the hydrolic noise. After almost 45 min digging and moving around I got it to make the noise. The mechanic looked it over and checked my pressure it was only 1400psi. He raised the pressure and tried again and still made the noise. He and the other mechanic agreed its in the relief valve when the fluid gets real hot and assured me its normal. It could be a variety of things from a slightly over tighted hydrolic line and just plain vibration from the relief valve. I am satisfied with his assessment after watching the whole time and agree nothing to worry about. Just an FYI. Mike R.

Micky. Thanks for the follow up. Makes me wonder what psi is at on my BX25.

I checked my pressure and its at 1750psi, a little low but still within spec.

As for your mechanics diagnoses, I dont think it would be acceptable to me. For one, mine did not make this noise for approx. 175hrs and now its there. As a technician myself, this tells me that something is wearing or failing and with my luck it will fail just after warranty runs out. Once that happens then you have a fight even if its documented that that you had it checked.

Also, mine is loud enough that it is embarrassing for a fairly new machine.

Do you know if they tried changing any QC or if they took the relief valve out to check the o-rings. My Kubota mechanic mentioned both but I have not checked it myself or had the BX brought in yet. I will be getting it checked once I return from work.
