supercharger Maintenance

Yup... planning on more fun stuff! Every now and again at idle I hear a tick sound near the supercharger... not sure if it is supercharger or not, but regardless I'm planning on changing out the coupler with one from zzp. I was planning on doing the snout seal and bearings also, but since I can't find a supercharger pulley puller I'm thinking of passing.. can't convince myself paying 30 dollars to rent a tool for a couple minutes is worth it.. my questions.. 1. I read that the snout gasket will not be reusable and just use a gasket maker sealant ... is this accurate and will provide a good seal? 2. What's the expectancy of the bearings? Are they generally reliable on high mileage chargers? I have 100k on it.. think ill be solid for awhile, or suck it up and replace the bearings now? 2001 gtp. Thanks
 


Does your GP have digital climate control? If so that tick could be the ac compressor kicking in.

I would just change the coupler, I have not read to many stories of peoples bearings and snout seals going out but it is possible. And 100k is not a high mileage charger my stock blower has ~176k on it and it ran like a champ.
 
That's what I'm leaning towards... no point in wasting money.... will I be able to simple pull off the old coupler? I didn't find any specific tools needed for removal process..

If you are coming up to my place next weekend, we can just do it then. If you haven't bought anything yet, you will need a new coupler, 2 bottles of GM supercharger fluid, and a tube of anaerobic sealant.

I wouldn't worry at all about the snout bearings and seals. I have over 281k miles on the original snout bearings and seals on my GTP and don't have any issues.

But like you read, there is no "gasket" between the snout and the supercharger rotors. It is just sealed with a sealant called anaerobic sealer, which means it will seal without being exposed to oxygen, as opposed to something like RTV gasket maker which needs oxygen to cure. And as mentioned, I wouldn't worry about the bearings as they typically are not a part that goes bad. And if they do, it is easier to pick up a used snout or entire supercharger for less than it would cost to do the bearings alone.
 
Damn... I thought 100k was getting up there lol.. yea definitely, that works for me.. ill make sure to order everything awhile. I should be fine, but it will be nice to have someone knowledgeable around if I have a question. Thanks zef!
