Jack's Comments:

Service replacement Ford water pump fan hub.  Fits all 3/4" bearing shafts.
Install 1" from the bearing housing hub to the front face of the fan hub. Press fit.

Install Tip:
When pressing this hub on make sure the bearing shaft is perfectly centered on the hub before pressing in place. 

Warning:
If this fan hub is not installed correctly it can cause the fan to wobble. This condition can result in the fan hub loosing up enough to fall off the bearing shaft. If you install the hub crooked you will need to replace it with a new one, do not attempt to straiten it out.
