I received a Athearn SD45 today that a Gentleman says won't run to well..Ok I told him I charge a $4.00 fee for tear down,inspection and analyzing.He agreed to this.Ok.I just finish tearing this unit down and can understand why this poor unit will not hardly run at full throttle.First I have been in the repair business for the last 25 years and I have never seen anybody use Vaseline for grease. Yes,Vaseline. The gearboxes and drive shafts is full of this crap. I have already called the Gentleman back and told him what I found and what it will cost for cleaning this mess up(my exact words) and I have a use SD45 drive that I could sell him cheaper then I could clean this unit for..I was told to proceed with the cleaning and tune up as he wanted to keep the original drive. My question does anybody know of a easy way of removing Vaseline other then the hard way? Like I said I never seen anybody use Vaseline for grease in the 25 years I been doing repair work.
