HST Noise (video) - New to me B2620

[Fredmeyer]

Hi,

I have had a few BX Kubota's over the years and am familiar with HST sounds. My B2620 sounds pretty normal until it gets under load and then it has a vibration sound that I assume is coming from the pump? Fluid is full on dip stick. Currently has 200 hrs on hydro oil and kubota spec filters . I hope it has UDT2 in it and will replace fluid with Kubota UDT2 and swap filters to make sure thats not the issue.

Sound can be heard here near the end of the video :

Has anyone else had a similar noise on their B26? Any ideas as to what it might be?

Thanks!

To me it sounds like either the clutch disk / pressure plate or propeller shaft joint issue.
But it could be an HST fluid issue.
If you haven't done it I would say 2 new Kubota filters and SUDT2 to start with.

Thanks! Changed fluid and filters to Kubota spec including the use of super UDT2 this am and no change in the noise. The drive shaft seems loose/rattly but I don't have anything to compare it to.

Does the amount of movement/noise in the video below seem out of spec? If so, how hard is this thing to change out?

B2620 drive shaft warn out?
