I have Zetor 8540 which makes a kind of whining noise. It seems to come from something which runs hydraulic pumps but disconnecting bigger pump doesn't make the noise go away. To my ear it seems to be some kind of bearing noise from a bearing which rotates allways when engine is running. Noise comes from somewhere between clutch and gearbox.
If I use hydraulics or change quick-change gear speed noise can get little different. But if I push clutch pedal down or use PTO it makes no difference.
There is enough oil and filters are clean. Any experience of this kind of problem? What could be wrong?
