We were able to get the pulley off, had to put pressure between the motor and pulley flang, while using a large hammer and punch on the bolt in the end of the crank shaft. Mine looked as though it had an adhessive on the tapered shaft.
I am wondering how to get the drive pulley off the motor on my 610 bobcat, it has the wisconsin motor. I have the outter part of the pulley off but am not sure how the rest comes off.
