Thanks for the offer... but it'* making so much noise that I don't think it will make it up there. I won't drive it to the corner and back. It sounds much louder than I've ever heard anything before... like metal on metal. I can't stress enough that it is very loud. I've heard the SC make noise before on cold winter days, before the engine is warmed up... That 'cold noise' was bearly noticable and most of the time you forgot it was even making any noise at all. But compared to this new noise that'* nothing!. This noise caught my attention immediately. It sounds like a catistophic failure is about to occur. I'm not driving this baby anywhere until it'* fixed.

I'm ordering a coupler and all the other parts for the unit now.

Any other thoughts guys?

Thanks again... Ace

I have a thought. Pull the SC and rip it apart before ordering, as long as you're not driving it anyway. That coupler may have broken apart, or there may be other damage.

Good point. Thanks for the advice Willwren!

This way, just in case, you can order bearings and seals if you need them at the same time. It'* cheaper to buy the coupler, bearings, seals, and oil from a single source as a kit.

Does ZZP sell this kit or only the coupler? It appears from the website that they only sell the coupler (and I know you don't work there so you might not know!). Any other sources for this kit if I need it?

Thanks.

Buy the M90 kit. We share the same parts on our M62'*. Wait....we had them FIRST.

They share OUR parts.

But don't buy it until you know what you need. This is actually a fun job. You'll enjoy it.

You might want to also look at the Harmonic Balancer if it is making that loud of a metallic sound....I just went through the same thing....I was getting a rattling, clinking noise at idle and thought it was the supercharger coupler. After getting it apart and finding a nearly brand new stock coupler, I finally found that the harmonic balancer had split and was clinking on the metal stop. Just a suggestion.

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?

Leverage may be applied differently by each belt. My boss just replaced his coupler (which WAS bad) and still has a clatter/rattle. I'm steering him towards the HB regardless of the belts. On his, the noise goes away with the SC/WP belt removed, but it'* not either of those or the idlers.

That leaves the HB, and his lower idler is bouncing.

Interesting... I'll keep it in mind for sure once this job is complete.

Still need local help from someone with power tools... Thanks!!
