B2320-Hydro-static Noise

[Crich]

My 2009-B2320 HST with 410 hrs has been making a whining noise which sounds like it is in hydro static . Happens more when its warming up and when changing from forward to reverse. Once it warms up for a half hour or so the noise seems to get better.

This has been going on for the last 20 or so operating hours. Recently did the 400 hr complete service and the noise hasn't gone away.

Any ideas?

What fluid did you put in it?

Well I can't hear yours Crich but after I did my first 50 hour service and put the Canadian Kubota Premium UDT in I noticed my hydro whine got louder. Then did two other changes with same oil. It isn't horrible but it does whine.

I will probably dump again this spring and this time I bought a pail of Super UDT from the States to see if it makes any difference.

I've been wondering (since I am a Petro Canada distributor) if I should try the Petro Canada synthetic Duratran some time to see if it makes any difference. It is Kubota approved.
