Tx64 steering valve noise!

[foul mouth phil]

I've got a very irritating whining noise coming through the cab floor from the steering valve,it only goes away when you move the steering wheel around which is chuffin the baler man off,I've check the main things like oil level,return pipes for tightness,filter was changed this season,any help would be appreciated.

Vibration or oil induced?... could try removing trim and wd40 on the joints.

It's not vibration,it's more like oil induced.when you move the steering wheel from one way to the other it stops,doesn't make any difference if you use any of the other hydraulic services either.

Is it short of oil?

No oil levels ok and was changed with the filter last month.

Possible air in system then?, should clear itself though?

Might be air in the system or sucking air in somewhere,I've checked all the hydraulic lines.if you drop the engine revs a notch the noise goes.

Is the hydraulic pump belt tight enough and in good condition

To be honest haven't checked this but if it was slipping or worn some thing else would be struggling like the header or unloading auger ,but everything works fine,the header, the reel, the steering is as it should be,but there is a constant whine coming from the steering colum.Might ask the mothering law if she wants a ride on the buddy seat, it might go away.
