Cleaning Gen V Supercharger out

**geforcextreme** · 03-12-2010

I purchased a Gen V with an unknown amount of miles. All I know is its a 04-05 model. I tore the SC apart so I could give the housing to my buddy to get the H-bar removed.

Well the bearings and the coupler are actually in great shape. I was going to buy a new SC coupler however being the OEM one is still very tight should I even bother? Being I already have it torn apart, most likely will.

Now the rotors are coated with a nice layer of carbon/grease I guess most likely from the stock PCV/EGR. I would like to degrease the stuff off the rotors but not sure what to use on it.

Should I just use a watered down mixture of degreaser or citric based degreaser and spray the rotors down?

Also as far as the bearings go, should i put a little bearing grease on the end of the rotor tips before sliding them back into the bearings? I am just not sure if bearing grease is ok to use? Its just when I clean the rotors off, any grease no the tip of the rotor blades is going to come off.

When I re-seal the snout onto the SC housing, is high temp red RTV stuff fine?

Do I only apply it to the snout side and not the rotor pack assembly that bolts onto the SC housing itself?

Do I need to apply any thread locker to the snout bolts?

leave the rotors alone. more gunk on them means they seal better and make more boost. why does everyone want them clean like you get to look at them all the time?

high temp bearing grease should work fine.

i never used any RTV and my blowers never leaked. notice how the edge of the snout has a rough layer on it? thats supposed to be your seal. however, if you wnat to put some RTV on the snout only, not between the rotor pack and housing. thread locker is not necessary either, but up to you.

^how ever GenV's require thread sealer on the two bottom bolts in the middle for the snout.

When I had mine apart I used anerobic sealer on the snout and did not use any threadlocker on the bottom bolts and this was 20k ago.

i used carb cleaner on rotors and case, anerobic gasket maker on snout mating surface only, s/c bearing grease on case bearings, white thread locker on new bolts, oh and a zzp coupler

why remove the H bar?

Why did you clean the rotors? carbon buildup = better seal.

You remove the H bar if you're going I/C'd

Thanks guys I am going to keep the rotors as-is.

I am removing the H-bar because I am intercooled. I also wanted to remove the H-bar because I am installing the gen V SC onto a gen III IC core. SO to get the best I can reusing my old IC core, wanted to remove the H-bar from the outlet.

What do you do when you wanna remove the H bar and your needle bearings have been replaces via the drill a hole behind then and press them out with grease method?

Also, these pics are so deceiving, the actual blower outlet is tiny IMO.

What? Lol

Just a helpful tip from my friend at Magnuson I am passing on to you all. Not saying you HAVE to do that, but it does keep the snout oil from seeping out. I didn't do this on my first GenV build for myself, but I did on my second once he told me this, and all my customers who have me polish and rebuild theirs get that too. I don't like leaks, or returning customers for problems.

And yes, when you have a supercharger apart...don't clean the rotors of their build up. I don't even recommend cleaning the inside of the case at all, but some people want me to do it, and for the next few thousand miles, the rotors can be a little more louder because of the cleaning increased tolerances and make a bigger gap between the rotors and the case wall.
