my theory on it is this. The cap screw appears to hold the crank onto the arm. the crank bolts for hte arm just hold it from wobbling on the BB. said cover came loose, and the crank arm worked its way off, then just sheared off like that. the BB is an external type, as this is a 2 piece crank, with the shaft integrated on the fuji track pro. so the new crank will have the entire assembly and ill just swap it out in a few seconds.
No. The big cap on the end of the spindle is only used to set the bearing preload. The two pinch bolts clamp the splines down and hold everything together. Same principle as a threadless stem. The crank's not going anywhere if the bolts are tightened properly.
If you swap it out "in seconds," just make sure you do it right, eh?
