I am trying to remove a model F waterpump. This engine has a horizontal shaft in the front which one side runs the mag and the other side runs the waterpump. I have removed the 4 flange mounting bolts from the engine along with the long bolt that holds the governor bracket to the front of the engine as per the manual instructions. The pumps starts to come off and has moved about 3/8 of an inch. It looks like the pump slides off the shaft but now I think the impeller is hitting the body so it will not come off without first removing the outside cover and then the impeller. Does this sound correct. I will try and post a picture. Thanks.
