Hello,
I tare down my old supercharger and willingto give information of what I can see and measure.

 

Nice work!

 

I need to change the bearing on my 05 srt 6 supercharger. Can you recommend a list of tools with sizes i would need?

 

Hello,
What bearing do you want to replace among No.1~5 below?
Wearing out No.4 needle bearing makes supercharger oil leakage. New Oil seal could not stop oil leaking perfectly without changing No.4 needle bearing.
As you know, most of noise is caused by No.5.
Wearing out No.1 makes scratch on rotor blade.
I do not recommand changing No.2 & 3, If you do not have certainty.
No.3 is deep groove type and hardly makes problem in my thought.
No.2 is double bearing and have double seals, so a slight wearing does not makes problems I think.
Wrong installation of No.2 makes serious problem.

 

No. 5. Its creating the grinding noise that's driving me crazy. I'm not very experienced with mechanics but after researching this looked like a problem I could fix.

 

That is the supercharger bearing, if your not leaking oil and you hear a grinding noise it is likely this bearing. https://www.needswings.com/superchar...ey-bearing-c32

A machine shop can swap them out for you as it is a press bearing. Thats what I did when I needed to replace mine, I took it to a machine shop and had them press the old one out and press the new one in. They charged me $25 to do the job. I would have did it myself but I don't have bearing press and im not about to bang on pulley as you risk damaging it.

 

How do you feel about the hot & cold method? Tapping out the old bearing then cooling new bearing & heating the pulley. What size torx wrench would I need & what size wrench to remove the pulley bolt? Can I use hose clamps to hold the clutch or should I get a belt wrench?

 

Also supercharger oil. My car has 117000 miles & I have no idea if its ever been changed. Is there a way I can check it?

 

Lots of information on this forum, on google and you tube that will address most of your questions. Not a bad idea to dive into the information currently available and circle back with Additional questions not uncovered with your search.

 

Yeah I've been Googling & watching lots of videos but there isn't a whole lot on srt6. More just comparable Mercedes. Some stuff is like definitely replace the oil & then others are like don't ever change supercharger oil

 

Just to be sure, change it anyway just for peace of mind.
I am changing mine at 42,000 miles just because it is something to do.

 

The hot cold method does work, I’ve done it before and you have nothing to lose.

i built a press (instructions from you tube) for the second bearing I had to R&R

 

do you know of anyone that can rebuild a SC or one for sale, I blew mine, any info would help.

 

EBay
tbis one appears to be pretty pricey. They show up regularly for the $600 range.

~ I had PSE Superchargers rebuild mine, and supply me with the last 2 known OEM pulleys and bearings from a Fiat warehouse in the UK. It's on a shelf as a spare in my shop. The price was not cheap by any means. Over 5G for all.
~ I was told that to remove one of the bearings, not sure which, the unit needed to be heated to around 800 F in an oven to melt the epoxy from a grooved bearing and that any other method to remove that bearing usually results in damaging the casing of the S.C.
~ Your photos reveal that the teflon coating is gone from your twin screws not to mention the scratches. I didn't spot the bearing with the epoxy groove but I am curious how you removed it.

 

i have 1 new in box oem main sc pulley on the shelf here

 

I figure you're right. I ordered the oil

 

Hello,
There are epoxy grooves where bearings are located.
I think these epoxy is for thermal expansion of bearing or casting of S.C.
So It must not be melted because it should work.
Bearings could be pulled out with press machine and some handy tools without heating but it was not easy work.
Please refer to below pictures.
One important thing is that middle 2-bearings should be installed front face each other.

 

This forum owes you a debt of gratitude for the descriptions and photos of something SRT owners have but are fortunately not likely to see in pieces.
Thank you for the great photos they explain a lot.

 

did your oil leak got fixed with new bearing?
