Error. The water pump shaft has threads only on one end; I’ve never seen one with threads on both ends.
For the maintenance of water pumps, it is required that the shaft surface be smooth with no erosion, that the keyways and keys remain secure, that the threads at both ends are not damaged, and that the shaft diameter is free from any damage or deformation. ( ) Right
