FX45 owners please help, have I been sent the wrong part?

Take a punch and small hammer and tap on the outer edge (race) of the bearing to get the high edge down. Be carefull not to allow the punch to damage the seal! This should allow you to get the bearing in flush with the pulley lip! Cant hurt to try as you apparently are going to get a whole new assembly anyway? I am a old retired mechanical engineer so I am not just guessing at what you can do. Good luck!
 
I tried to do that, I located the "high side" and tapped on it with a punch and a heavy rubber hammer, the poor pulley couldn't take any more beating, it was squeaking like if I was hitting a coca can.

It is a design issue, beside the weak structure, the bearing seat isn't too deep, in which such a thin bearing may tilt while being pushed in and no guarantee for a flush seating, probably made in purpose so we buy the whole assembly with 94$ instead of changing the cheep bearing for 3$.

The idler pulley however, the wrong part, is a cast structure, much thicker with deeper bearing seat, if you notice in the picture it takes two bearings together side by side, even if they were not pressed all the way in, they won't flush but they won't cause the pulley to wobble either, equal gap will be lift all around.

Guys, check this out, so I bought ACDelco auto tensioner pulleys right, two of them, 20$ each. I received them and surprisingly they were made with far better quality than the OEM, they are much thicker and have more rigid structure, so much for 90$ entire assembly with a "disposal" pulley, I have attached here below a close up picture for you to better understand what I am talking about.

Looks good. Your making noise? Any chance you have a picture of the stock one. Not that I don't trust your judgement, just want to take a quick peek. :wink:
