I am trying to install the pulley and it is taking a lot of hammering to get it to move I am not even to the front seal or to where I can use the bolt to pull it in. Is this normal with installation? I know it is tight but it pulled off pretty easily with a puller. The key seems pretty tight but it's the one I took out. Is the key suppose to be so tight that even tapping it a bit the key does not want to go in the slot? Any advice? Or is this all normal for the pulley on a 292
