I'm confused, does the AEM pulley are supposed to be smaller in diameter than the oem one or not ?

I've bought PowerStering pulley on ebay and it's smaller than my original one, does it's ok or the guy send me a pulley who dont fit for my car (civic EX 96) ?

Thanks !

 

Larger than the pulley it's replacing.

You're probably holding the AEM alternator pulley in your hand, not the PS pulley. It's like 3" to 3.5" in diameter I think.

 

Here's my pulley

 

That's an alternator pulley. The power steering pulley is an inch or two larger in diameter.

 

what the point of tyhe pulley is is to spin slower, if the radius is larger it will spin slower causing less parasitic loss to the rotating assembly, therefore gaining more power, it also allows the motor to work less because of the reduced mass and increased radius
