Our current program runs it to 4100rpm.
We removed the service panels, turned off the heat and opened the doors.
With a shop blower fan applied and cooling externally, the temp doesn’t go above 83 Celsius.
The attached photo is of the rear Spindle Bearing Assembly (I don’t know the actual terms for that section of the spindle.)
Is this the area from which the high temperatures are being indicated from within diagnostics 403 line?
I just need to know... if we continue to run until failure occurs, or have we potentially put the problem source in the crosshairs?
