Rebuild a Supercharger

Sinse the wether as cone colder i have started to noticed more and more ratteling noise from the SC when i start the engine (when it's still cold)
but when it warm's up the noise is cone.
i readed from some topics that the problem is coupler?
my car as 140k miles on it.
the last owener told me that he changed the SC oil on summer and that the SC on my car was taken from a car what had 43k miles on it.
but...anyways ...the last owner lied to me about some thing's...so i'm anyways not trusting or beliving anythign what he told me. just want to be sure that everything will be done perfectly now.
So i was thinking if i will have to open the SC and change the coupler and oil.
i started to shearch from ebay.
and i found a rebuilding kit.

is this all what i need to rebuild series II riv's SC?
are the price ok? cos i have no idea what those thing's relly cost in USA.

Timo,

You should know that replacing only the coupler is a lot easier than a complete rebuild. Also, the coupler is usually the reason for supercharger noise.

Replacing the coupler costs about $35 for the part, and can be done by removing the snout, but leaving SC pulley still attached. Takes about 1-2 hours.

Rebuilding the entire blower requires a bigger investment, and you must remove the snout and then pull the SC pulley off using a special tool. It is pressed on there pretty good!

Here is a write-up for a Series I blower. Series II is very much the same, but remember, you can do this with the blower remaining on the car:

Good luck!

that sound that you are talking about at startup are you sure its not your intake? when I start up it sounds very loud because I have a "short ram" air intake. or do I need to replace the coupler too......

here it is...thats the sound..
