Good morning
I have a289 D and it has started to make a high pitch whining noise when I turn left and right at high power settings. At low power all is quiet. Fluid is new and filter replaced. No evidence of leaks. I drained the final drives and they flew it in. Both was rather dark to almost black, but there was no metal on the drain plug magnets. The machine has about 1300 hours.
Any suggestions a what to start to look for?
Thanks
Fred.
