Motobecane Mixte: Bottom Bracket Rebuild

 This is the bottom bracket dis-assembled and cleaned.
Pretty straight-forward.  Washer, bearings, bottom bracket and...
 What is that strange plastic sheath that goes around the bottom bracket???
 I re-assmebled the whole contraption and I thought "WOW! This sheath makes a great grease trap!"
WRONG.  I'm not quite sure what this sheath does but with the bearings trapped inside, they won't
fit inside the cups of the bracket covers.  Well...I put the bearings on correctly and put the sheath in between them for what it's worth.  Works like a dream!
