how can any mechanical part last an entire life cycle without any maintenance or preventative maintenance done? **** man, i'm a well oiled machince but i need lubed up every once in a while.

 

i agree...thats like saying the engine oil can last forever

 

If I just un bold the SC and take it off to install my stage 2 pulley will any oil spill out or is it sealed in my something???

 

its sealed (the oil is in the snout) removal of the S/C won't have it leak.........

 

I've had my blower apart a few times now.
As for service on it. If you are running smaller pulleys i would suggest that you definitely regrease the needle bearings every few thousand miles or so especially if you are running methanol injection. Meth seems to eat away at the grease. I have changed the oil in the blower a couple of times now, but just out of necessity. I had to remove the snout so i had to drain the oil. All in all very simple to do work on these things.

 

Life cycle = 150k Miles

MANY components on your vehicle which in the past used to require service and lube.

for example, how many people still grease their chassis and suspension components? The grease fittings went away a long time ago.

The oil in in a sealed compartment, which means no contamination can enter the oil. Unlike an engine, which has blowby, gasoline, and air passing through the oil, the supercharger oil does not have 99% of this contamination entering it, therefore, no oil changes are necessary

Most people on this board dont remember how much maintence was required on older vehicles, today, anything beyond oil changes and new tires is considered "too much" by the automotive public and likewise, all the parts on a car are continually being updated to meet these requirements. The supercharger is no exception and GM does not call out service to the supercharger for at LEAST 100k miles and neither does eaton.

 

tis true you used to have to adjust your valves and everything

 

engine oil has more contamination that enters it and a more harsh environment

Water
gasoline
air (oxidation)
extreme heat

Supercharger oil has a very easy life, nothing enters or leaves


but to a few points mentioned above, If you are having meth or other items pass through the supercharger, definately check the unit. Your roller bearings will be fine if just running a smaller pulley, however, keep an eye on them when running any sort of liquid or fuel through it.

 

like the cage 2 may enter 1 may leave

 

Brian, I finally have a weekend off coming up and I'm definately thinking this is the weekend to put my new coupler in, and re grease.....does the coupler just pop on, or do you have to press it on, i.e. by hand or special tools?.....and when re greasing the needle bearings, do you take them out and repack them or just rub grease on them packed?...lol, and do you have the torque specs for the snout for when I put it back on? R they necessary?

 

k, so I serviced the S/C tonight....very easy.....had the s/c off the car, replaced the coupler, removed the rotors to regrease the needle bearings, resealed everything, and put back on the car, in about an hour...maybe an hour and 15 minutes......long story short the knocking has gone away for the moment but I found that I really need to get my S/C machined/ ported.......when the coupler wore and the rotors had freeplay it caused them to rub each other and the s/c housing...and as you can see from the photos its not pretty..........













bump

 

Ditto.
Apart from the maintenance schedule provided in your owners manual (there is a S/C service @ 100 or 150K), I wouldn't touch the damn thing!
With bearings aside, there is no metal on metal contact within the unit to speak of and the lube is there for cooling/controling expansion within the housing itself.
In any event it the blower failed, it would be covered by the warranty (unless you've been playing with it-wich they'll know).
Personally, I'll drive it till it expoldes.

 

i agree if you're going to leave the s/c stock then don't touch it...but unfortunately, smaller pullies spin the s/c faster and up the temps. inside...which cause the coupler gets worn, and the bearings lose some lubrication (mine were almost bone dry)...thus causing what happened in my pics above.....although there shouldn't be contact there ends up being contact, lol.....a design flaw that eaton, and in turn, GM, has known about but didn't correct for years.......so yes, you have to pay to play, and service will be required if you want to maintain your s/c.....unless your just lazy and made of money, and then you can just replace it everytime it starts knocking or you have spool lag..............your choice

 

You used gasket maker when you resealed the snout right?

 

yeah...the gasket maker provided by zzp, everything works fine......why?

 

Just making sure because you didn't mention it. Just looking out for ya.
