The blades wear down and the coating wears off. You can thank meth injection and or nitroius. A normal SC should not look like that for a long long time. Something very very cold or very very hot will wear them like that pic.

 

It is teflon

 

I was told that our GEN 5 M62 did not have teflon coatings.

 

No Eaton supercharger has teflon rotor coatings...

 

So what is the black coating on the rotors?

 

Ok... on the Gen 5 SC they used APC (Abradable Powder Coating) which is a zirconium/ceramic/silicone coating.

 

Thanks rnjmur!

 

Just thought I dig this old post up bc I'm getting ready to change my coupler in hopes to correct the knocking in my S/C....I was hoping to find a "how to" on Coupler replacement bc I've never actually taken apart a S/C......Also, 100ml is definately wrong.....I'm on my second S/C and I couldn't find a spec. anywhere so when I took my old S/C off I drained it to get the spec...From factory our S/C's come filled with 2.5 fl oz. or roughly 75ml of oil don't over do it either bc if it doesn't blow the gaskets it will cause you to lose boost (the more overfilled the more of a loss)...trust me bc I've done it!

bump

 

the super-chargers on a 3.8l had a drain and fill port. our super chargers don't require any maintnence. that what gm service info states.

 

Are there two plugs, one for draining and one for filling or just one plug?

 

Can anyone take a picture of the bolt to remove off the charger to change the oil?

 

...dude, you're like the 100th person to say that.....GM also doesn't tell you to run the dog **** out of the car...so if you do, u can expect to have signs of wear show up....faster.....so certain ppl need to quit whining about actually having to maintain the car they own...if you can't maintain it, and are bitching about doing so...don't drive it.....


its one screw that has an flat allen head on it and is located on the backside of the base of the snout (when facing the engine bay).......its not hard to find....

 

quick question how hard is it to change couplers?

 

supposedly...very easy just take the snout off, then pull coupler off, and press new one on....(hopefully by hand, lol), then re-seal with GM Gasket Maker....I'll let ya know hopefully after this weekend....

 

So did you get a chance to change out the coupler yet

 

actually i didnt..i came down with a cold or flu or something, but as soon as i do, i'll post

 

There is too much Mis-information in this thread...

Please dont listen to most of this information.

Exactly

 

i change my blower oil every6 month ... i also regrease my bearings and reseal it i'll try and do a how to this weekend when i do it

 

you must enjoy wasting your time....

for everyone else, this is not needed (obviously).. but again.. nobody is stopping you.

 

Why? Eaton will tell you the same thing, no maintenance is needed on it.

 

I called Eaton for the M62. They claimed service needs to be done every 12k miles.

 

subscribed to this post for later use. good question to the op

 

for later use

 

NO THEY DIDNT.

I can tell you for CERTAIN that nobody from eaton (who knows about Superchargers) told you that it required service.

Eaton designs them to last the entire life cycle of the engine without maintenece
