Thanks guys. I was not indicating that temperature is a problem but rather just would like to know what temp is likely to be, hoping someone might know. Is it 50, 100, 150 or 200C? As I look at grease, temp thins it out and I notice that I often see my moly has moved away from the spline and has spun out in radial lines. So I wonder if I obtained a higher temp rated extreme pressure grease then I might be actually better off.
