It took about an hour to get the SC off the motor, another 45 minutes to clean the intake and the SC. If I put my hand on the splines of the SC and turn the pulley with the other hand, there is quite a bit of back and forth play between the two of them. I fairly certain this is not a good thing.
So now I have a new issue... I can't get the damn nose cone off the SC!. The 10mm bolts are so tight that I can about 1/2 of them loose with my hand tools, the others are so tight I'm risking stripping them or rounding them off - another bad thing to say the least.
Does any local to Minneapolis MN have power tools with hammer action to assist with this? I'm more than willing to take the SC for a little ride to accomplish this task... just don't laugh at my wifes minivan.
Regarding the Harmonic Balancer - this makes some sense given the noise is coming from the same general location on the engine. But what puzzles me is if it were the HB the noise would not stop with the removal of the inside SC belt - correct? The HB turns all the time and drives both belts on the vehicle... so if the noise stopped when both belts were removed I would tend to think that the problem is not related to the HB. Unless I'm missing something here... anyone have any input?
