Update: after talking to a few other people as well as Maxxx, I learned that there are a few different versions of the Maxxx 148mm pump in existence. My pump (purchased Dec 2013) uses 6205 single row deep groove roller bearing in both the front and the back where as the older Maxxx pumps use a 5205 bearing in the front and a 6205 in the back. With the bearing change, changes to the driveshaft were also made and the impeller fitment between the different versions of the 148mm pump/driveshaft seem to also vary.
