I am trying to make sense about the whole thing before I install this pulley.
The stock pulley has a steel ring around it, so does the pulley from Unorthodox Racing. The one that's from Definitive Motorsport comes with bronze bushing. The one from RVM does not come with anything.
Wear on the pulley surface is caused by (correct me if I am wrong here) having the pulley rubbing another hard surface while rotating.
Now, the one that does not make sense is this:
How could aluminum could have grooves from rubbing with rubber oil seal?
I understand that this would be possible if the pulley was rubbing with steel surface or something, but with rubber??

DanNY,
I was thinking the same thing too.
But now that I have said that, why the stock pulley and the ones from Definitive/Unorthodox has the rings?
Another thing, if the pulley has scratches, the installer *might* overtighten the bolt (or do something else) that makes the pulley sit un-evenly on the crankshaft.
Perhaps this is the culprit...

and they are capable of eating through those soft aluminum....
and if enough time is giving it can make those marks on steel UDP also... that is why older chevy cars just replace it by replacing the steel sleves on the UDP then changing out the UDP...

This is interesting
So basically the pulley would be eaten no matter what (but the rate is much slower with the steel ones.
Do you guys know which one is harder, bronze or steel? (I forgot my Material Science class from college years...).
My oil seal is on the way to my apartment. I will see how hard is the seal.
I could say that incorrect belt tension could be attributed to this problem as well, causing the pulley to be "pushed" to one side instead putting it straight on the crankshaft. This would contribute uneven wear along the edges (correct me if I am wrong, I am just trying to make sense of what happens here).

Re: This is interesting
It seems that I am answering my own question here:
][/QUOTE]Copper alloys have excellent wear characteristics against steel surfaces. The broad family of aluminum bronze and nickel-aluminum bronze alloys in both wrought and cast form offer the best combinations of resistance to wear, abrasion, fatigue, deformation and corrosion. Recommended applications include slides, gibs, wear plates, mold locking devices, sleeve bearings, guide pin bushings, lifter blades, ejector sleeves and pins, and rotating mold components.

but when i had my RVM UDP removed due to oil leak...
my UDP had nice round and even indentation around the UDP
and the oil seal was in perfect condition since it has only been used like 3 month... but i still replaced it brand new one since i already had one to replace it with stock pulley incase the oil seal was bad.... but it wasn't the case...

copper is an excellent bushing for wear and etc since copper tends to have lubricating properties...but copper is soft and under heavy load copper will fail.
belt tension sounds more realistic. it's constantly pulling on one direction...while it spins it's going to wear a groove.
if you have an oil seal pick it up and look at it.
the "lip" of the seal where it would hit the actual crank is soft. behind that there's a spring retainer that keeps a light pressure/tension on the lip. the outter edge there it sits on it's housing is metal covered w/ rubber.
if you're at the point where you're at the outter lip..you car should be leaking oil like crazy. that's the only point where i would see the pulley getting damaged.
99maxi - no it's not possible to reuse the stock sleeve.

That means the oil seal is actually putting enough pressure to "push" that part of your UDP to create that indentation.
Harder metal is required then.

Belt tension is very likely to be the cause (rather than rubber putting tons of pressure on the sleeve causing it an abnormal wear within 3 months).

The RVM pulley has a metal timing ring around the outside the same as the UR one, they are identical.
There is no other metal on the UR either other than the timing ring just the the RVM one. I have had both, there is NO difference. There is nothing on the UR pulley where the shaft slides on, it is aluminum all the way through. The only steel is the timing ring.

Jime,
It's not the timing ring. Please go back to DanNY post (on page 2/3 probably) and look at the arrow. It's where the thing starts to wear.

that link for $115 is not the UR pulley. I was going to purchase that pulley, but didn't know its results. they just started making the pulley(i think) and i'll have to see how my pulley looks when it comes in.

I uninstalled my rvm pulley last week and the rough starts and check engine light is all gone. it was a cranksensor code. the timing ring was there it was the same size of the stock pulley but the ecu still got a code. I asked for help from rvm and all they said was realigned it again reinstall blah blah blah. in two word emails. Anyone know the solution of even installing it on the car?

okay here is the pic..... sorry about the lighting..
as u can see where the oil seal kind of damage the UDP that is why u need the steel sleeve to protect it...
this is how i got the UDP well w/o the dent made by the oil seal...... nothing to protect the soft aluminum....
