The service manual is correct. As long as the bearing spins freely, you may never notice any difference. However, the purpose of the lock collar is to lock the bearing to the shaft. You want the collar to be locked in such a way that the normal rotation of the crankshaft keeps the collar tight on the bearing. If the lock collar was to be locked opposite the rotation of the crankshaft, being that the set screws lock the collar to the shaft, any movement in direction of normal rotation would unlock the collar from the bearing. Lock collar must be locked counterclockwise or in same direction as rotation of the crankshaft.
