Need to take it out , 134 x 73 i think is the size i am told a reply from another site but since i thread the crank is damaged was hoping to make sure I could source spares before removing, Suntour Hesc stuff is a bit rare ...thx for the replyShow us a pic to be sure but one would think a Std english thread type, these are approx. a max 33.9mm in dia.
For the shell width simply measure the BB shell under neath it will be 63 or 73mm,
for overall length BB simple put a tape on it or a calliper to measure from axle end to axle end. Which overall length one buys will alter the Q factor, one wouldn't go less then already fitted.
