I am trying to rebuild a 11hp Briggs and Stratton model 253417-0637-01 for my Cub Cadet 1100. My question is how do you remove the booster fan assembly from the crankshaft. I tried to put my puller on it and cranked it down with the impact gun but nothing budged. I tried the 3 bolt pattern and the 2 bolt pattern. The 2 bolt pattern seems to goes thru the booster fan into the flywheel that is behind it. Any help would be appreciated as I am trying to get this tractor up and running for my wife.
