I'm not sure which pulley you have by looking at the photos but I THINK that's a Code3 Gen2 pulley (the Gen1 had those front to back grooves and the Gen2 looks like the one in your photos). IF that's what you have it has a good reputation of being a reliable pulley. Put in a bit more shim and you should be good to go with no worries.
I am still not clear on where that pulley was purchased. Did it come from Eurocharged? If so it is NOT a Code3 and it may be one of the Eurocharged original design / release pulleys which have a history of problems and failures (as detailed in onehundred80's post). Eurocharged SHOULD be able to determine what pulley they sent on your order. If it is from the original batch they should be willing to exchange it for you.
