I was riding down the trail yesterday and started to here a whistling noise followed by a foul smell. I thought it was my belt but when I looked I saw smoke coming out of the DD. It looked like some of the fluid had come out of the DD (along where the two case halves mate. I took it apart tonight and haven't found any bad bearings or gears. There was probably between 4-6 ounces of fluid left in it. There were some small metal shavings but I haven't figured out where they came from yet. Is it normal for the planetary assembly to be a little loose? The DD spun normally when it was still together. Is my DD okay or am I in trouble? Any info or suggestions is appreciated.
