Fan won't come off the water pump shaft

[Tom Endy]

You can make a knock off tool. Go to the local hardware store and purchase a bolt about two inches long that has the same threads as the pump shaft. Also buy two nuts that will screw onto the bolt.

Screw one nut onto the bolt the other onto the pump shaft. Position the nut on the shaft so half of it is on the shaft. Screw the bolt into the other half until it is tight against the shaft. Run the nut on the bolt down against the other nut and tighten it.

Hold the assembly by the fan and snack the end of the bolt a number of times with a hammer until the fan comes loose from the pump shaft.
