Is my supercharger SHOT ?

Also I felt behind the rear bearings and it wasn't open so I don't see how to remove them lol

 

The one I bought made a similar noise before it was rebuilt and was 100% fine afterwards. I don't see any scarring on the inner walls. I think you'll be fine.

 

Did your rotor packs move though? They move side to side and

I'm pretty sure the rear bearings hold that together i think mine did that also

 

Ok cool. The nose cone actually feels smooth but I'm still gonna do it... Where do the rear bearings come out of ? Hoping I don't have one of those sealed ones

 

Don't know. I paid someone to rebuild mine and then I sold the whole unit haha. Regrets.

 

Once I'm done putting my kid to sleep I'll check out the videos and comment.

 

i know one pushes through and falls out but ended having to machine a tool to pull the other out.

 

Is there a way to see if mine will fall out the manifold like others ? Or if it's sealed ?

 

i really don't know if there is a way to find out. it has to be a made by date or something

 

Looks fine to me, the rotors will contact each other and look loose outside of the housing. The rear needle bearings will secure the rotors and cause them to spin freely without touching.

The housing looks very normal to me and no major scarring or gouges in the rotors or rear of the SC housing. I had a SC that contacted the rear of the housing and it created very noticeable gouges and the ends of the rotors were all messed up. Yours look fine to me.

As above, it's normal for them to move side to side. It's vertical movement that could be a problem.

It sounds like they are moving freely and not catching on anything. The vertical movement (pulling the gears towards you) seems a bit much though. That movement might be what is causing your sounds as the rotors are turning super fast and slightly oscillating. Post a picture of the rotor plate where the rotors are pressed into. Also can you take a video of the rotors against the rotor plate and you pulling/pushing the gears? That will help me see the movement better.



BTW, for anyone wondering where the rear needle bearings go out of here is one spot that may or may not be sealed. That cylinder looking spot in the circled area is where the rotor sits in. If it isn't seal you can see the end of the rotor bearing. That way you can just press the bearing out the housing and it will come out of that area with some finagling.



The other needle bearing is able to be pressed out of the back of the housing (it is not sealed in, at least the 3 black SC's I've rebuilt) and will come out the 2nd or 3rd manifold hole once pushed though. Before pressing both out though be sure to feel or measure how far in they are pressed so you can duplicate that depth.

 

Right here ??

 

Yeah so it looks like it isn't contacting the rotor plate as there is no noticeable scarring but a video showing the movement would be a big help.

 

Ok so take a video showing that area while pushing and pulling the gear??

 

Yup, that will show how much movement there is.

 

Cool will get one tommorow
Also switching to a 2.2 pulley from a 2.1

So it does contact the rotor plate

 

Keep in mind when you install the nose cone it puts pressure on the gears and creates space between the rotors and plate. Looks okay to me as far as I can tell. I'd just replace the bearings in the housing, nose cone and change the coupler then put it back together. I then hooked up my impact to it and ran it at high speed to see if it makes and abnormal sounds. If nothing then slap it on. Also get me a pick of the back of that bearing like I circled about.
