I have been seeing alot of pulleys for sale. I found a guy selling what he claims to be a 1st gen style (with out the 6 allen bolts) JDM 4lb lower pulley. What I want to know is how do I tell if it is really a 4lb pulley? is there a marking on it somewhere? I did not see any. How big is the pulley supposed to be? Anyone have any ideas???

You can tell by the diameter of the pulley. Do a search, the correct size has been posted before...

here are pulley sizes from a search I did...

2# ~ 7.90"
3# ~ 8.17"
4# ~ 8.50"
5# ~ 8.75"
6# ~ 9.00"

 

Darn you SLVRLTNG... You beat me to it lol. I was just tryin to find them all myself...

Thanks fellas..... this helps me alot.... I am guessing that the pulley is measured from lip to lip across the center of the 14mm center bolt?

 

measure the outside diameter of the belt surface NOT the outside diameter of the pulley edge....JR

 

ok, I just measured this pulley, they guy I bought it from told me it was a 4#er I just measured 7 15/16" from the outer lip to the opposite outer lip.... Did I get screwed or am I measuring this wrong?????

 

You just measured a 2# pulley.

 

That is what I am thinking.... that I got screwed... I am going to have to make sure I am measuring this thing right. If so its going to hit the fan!!!!!!!!

 

Measure where the belt would go. The circle....

ok, I am not the sharpest knife in the drawer when it comes to this and the though of getting possible screwed on this deal is clouding my thoughts.... but I measured around the pulley where the belt goes and got 25" in a complete circle still wrong?

 

Wait nevermind, I take that back. WTF was I thinking... im an idiot. Forget me

ok, I posted some pics of what I am measuring... let me know if this helps some

if you divide that 25" measurement by 3.1415 you still get a 2# pulley......7.9577 , I think you got scre*ed...JR

 

Hmmmmm... I think JDM color coded his pulleys? If so, maybe you can ask him what you have...... Or maybe its not even JDM? HMMM!
