I carefully separated the pieces of this part and cleaned everything ( except the bearing) with de natured alcohol. Very carefully pressed everything back together and re-installed into my machine. Just out of curiosity because let's face it $6,919 is a good bit to spend on a part. After re-installing said part and re-assembling my machine I proceeded to put it to the test. From 1rpm-1,000rpm and back, forward and reverse, small jumps in speed, large jumps in speed. I am happy to say that this part works like a charm now. A few hours of labor and about $2 worth of de-natured alcohol later I managed to save $7k. Hope this helps anyone who might be looking for answers on this particular subject.
