EMD77 Run Test or "Spike Test"

Postby Hart79 » Wed May 04, 2016 9:03 am

Is a run test performed on an assembled D77 with wheel and axles applied? EMD 3950-7'talks about a run test for testing and checking the unit and monitoring the bearing temperature rise over ambient for two hours with directional change.
How must you seat the axle Babbitt support bearings?
I have found an engineering standard from Aussie that states they do run the assembly. I have also seen a demonstration performed on You Tube.
Is this a practice to affirm that the assembly is build up correctly?
