new crank

[HOLY SHEE-IT]

i just got a new wiseco crank (not hot rods) and is comes with an o-ring installed in the groove where the bearing retainer (c-clip) is supposed to go. should i use that instead of the retainer clip or remove the o-ring and use the clip? also there's o-rings on the inner bearings and the stator side bearing as well. is that normal?

my guess is there on there to keep crap out of the grooves on the bearings, do your inner bearings have the two small pins in them? ditch the o-rings and use the clips that were on your old crank...

that's what i was thinking too, that they might be there to keep the grooves clean, but no, the inner bearings had no pins but the clutch-side bearing does.....seems odd. all 4 bearings have the o-rings, though.
