Waterpump pulleys and fan won' budge

'61' 292 'Y' block, I can't seem to remove the pulley/fan assembly from the waterpump shaft. I've removed the four bolts and have pried with a wonder bar on the backside of the pulleys pretty heavy with no luck. Water pump spins freely so my prying has been alternated. Any tricks? Thanks for reading my post and any help is greatly appreciated. First major Ford endeavor.
 
There's probably rust on the front end of the water pump shaft, esp inside the fan's center hole.
Clean off as much as you can and put on some penetrating oil. After it soaks a bit keep working at it like you have been.
 
It's a triple pulley and a clutch fan so can't really see any shaft. I guess if I put a good helping of penetrating oil on it tonight, like you said, it's bound to get somewhere in there. I'll do some prying again in the morning and cross my fingers. I will report back. Thank you so much for your time.
 
The clutch fan is aluminum, they tend to stick pretty badly. Wiggle, spray the backside, wiggle more. On assembly, use never seize in the aluminum and on the shaft.
 
Thanks Frank, the end of the water pump shaft is not exposed so nothing for my gear puller to push on. The end of the water pump shaft is covered by the fan shaft/flange.

Thanks Don, do you guys know if the fan clutch shaft/flange and pulleys are one piece or two, I can't tell and it doesn't show one way or the other in the factory manual. I thinking maybe some heat. I'm almost in "just get it apart mode" because I'm sure if I pry any harder I'm going to bend or break something. I've removed the radiator and a/c condenser so not to poke holes in them. All of this just to get the a/c compressor mount off to remove power steering pump for rebuild. Transmission and torque converter was a piece of cake to r and r compared to this deal.

Just going to take a little time away from it and watch the truck race and then get back to it. Thanks for all your thoughts and anything else you can think of please post. Doug
 
An old mechanic friend of mine told me even low heat will help. He said the repeated (read patience) heating cooling cycle will break the rust or corrosion loose over several cycles. It's worked for me more than once, using just propane torches. With the aluminum clutch, you'd probably melt it or destroy the seals with an oxy/acl rig. I managed to free some badly rusted suspension parts this way. The hard part is "patience"
 
I was able to drive a wood chisel between the fan flange and front of pulley. That separated everything just enough to loosen it. Yes, I will replace the water pump since I had to beat on things with a hammer. Thank you for everybody's time and help.
