During driving practice, one of the 1/2" hexagonal flanged bearings (bearing the end of a gearbox output shaft) failed catastrophically. Failure originated in the inner ring of the bearing, which cracked at the hex points. These are natural weak points. This was repaired by replacement on the running drive train (Deux). On Prime's drive train, which was being assembled, the decision was made to turn the ends of the hex drive shafts down to 1/2" round so that stronger round flanged bearings could be used in lieu of the hexagonal bearings. This was completed during the meeting and Prime's drive sides assembled, excluding belts. Mass of drive side is 14.7 lb.
