Well I finally got the pump off last night. I had to beat on the pump for a long time and just made the sprocket spindle just more and more mushroomed. The aluminum collar definitely had corroded itself to the aluminum bracket which is was caused me so much trouble. I was able to find a used one for a decent price that I may purchase when the time comes. If anyone needs any motor pictures let me know as I basically have the motor down to a bare block with just the crank in it.
