Supercharger rattle at idle???? Here is the fix!



Heres the start



After removing the idler pulley, coolant crossover you can remove the 6 bolts holding on the nose section. This is a dry nose supercharger so you do not have to remove oil or re-oil the nose section. The bolts are really hard to get too but it can be done providing you have a selection of extensions and swivels.



There was NO WAY the coupler was going to come out of the SC side so I had to make a puller tool.



How the puller tool works....

Hard to tell but the old coupler has egg shaped holes. This slack causes the supercharger to rattle (sounds like rocks are rolling around) at idle. I paid something like 30$ for the new coupler.
The new one does NOT have eased edge holes and will be impossible to align the the units.....Had to take a razor to help the prongs align. This is an operation done 100% blind and you are doing it all from feel. No way to do it without taking some edge out....



New coupler installed!!!!!!

Now just put it all back together!!!! The annoying rattle is gone but its also sounds smoother under boost.....
If your charger is rattling at idle YOU NEED TO FIX IT! Left unfixed it will cause damage to the SC.

Good luck if you try this at home

I know this is kind of an old thread but where did you order this part, mine has that weird rattle and how much did it cost. I thought I had a bad bearing or something.....

Its one of those things that would take 1/2 the time if I had done one previously. Magnuson was ZERO help!!!

Total time was about 3-4 hours.

Make sure when you are reinstalling the nose that once you get the prongs from the nose mated with the coupler, install all the bolts around the nose with hand torque. Once all the bolt faces are set on the coupler, tighten the bolts one turn only and then do another in a X type pattern. This will insure the nose section is being pulled onto the SC body evenly. Periodically turn the pulley to insure there is no binding.

Also...it is not needed to use high torque to finish the nose bolts. Snug is fine.....just make sure that you do a final check to see if the pulley turns freely after the nose is reinstalled. You should be able to turn the pulley with 2 fingers, any more and you have a misalignment caused by too much torque on one side....loosen the bolts until the nose turns freely and try again.


Good luck

~JH

BTW:

I have about 30K miles on my SC after replacing the coupler with ZERO issues. Its amazing how that stupid piece of plastic can make the SC sound like its coming apart!
