The bearings folks will tell you that impact loading and bearings don't mix real well. Basically, little indents (brinnelling for those who might be looking to add the technical term to their vocab) left in the race ways will utlimately result in problems later on.
I talked to a fella who pulls and replaces flywheels on F series frequently. He said that he has had good success by taking advantage of thermal expansion. You can set your flywheel on the bbq grill for about half an hour until it's ~300 F. An infrared thermometer works well to gage the temp. Screw a couple bolts in threaded holes to help you handle the flywheel and pin. It doesn't hurt to put the dowel pin in the freezer for a couple hours. Of course, welders gloves are a "must have" to handle the hot flywheel.
You can slide the flywheel on the room temp crank shaft while another slides the pin home. After it was in position you can run the nut down while the flywheel is still hot to get in home position. Took a couple helpers to make it happen; but made a pretty tough job which could have taken minutes happen in less than 30 seconds.
Of course I have the utmost respect for Old-F20 and Cowmans' advice and am sure that they have had good success with their procedures.
I would be interested in seeing your puller. Was it fabricated or a commercial model? Would you be able to post a picture?
Good luck.
