+I wish I could upload some images. I believe the original guy who purchased the adapter had bought it around 2007. I finally got the bearing out to see if I could find any labeling on it. and to my surprise I did. "3209 MARLIN CRAWLER" was all it had on the bearing. I couldn't find anywhere online where they used a 3209 bearing, only bearing they list or put in their description is a 5209 bearing, upon further investigation it seems like the filling slot of the outter ring was part of the reason it failed. it had discoloration and started to crack at that same point.
