I thought the same thing when I initially open the box - that is that the red cap in the needle bearing opening was there to keep dirt from falling in. At some point I notice that one of the needles fell off - upon further investigation I confirmed that they are loose and held together by grease.

I do not have the part in front of me since it is at home - I do not recall any parts numbers stamped on the race but I may be wrong. Should I return it and purchase an OEM part?
