ATX lower idler pulley, I found a decent replacement.

[jmpSHO2nd]

My lower idler pulley was making noise so I matched one up as close as I could to our original. I think SHO Source sells the correct pulley but if you need one ASAP like I did then this is the perfect pulley. It comes with a sleeve for the middle that is almost exact in size to our pulley but you will have to reverse the sleeve to get the right spacing for the belt. Also you will need a shorter bolt but other than that it works great. Not sure if reversing the sleeve puts any more pressure on the bearing than is intended.

Here is the part number, I bought mine at a local auto parts store not sure what car it goes too. Goodyear part number 49038.

49038 turns out to fit most Chrysler products from 88-04, and is available on rockauto and autozone for example, for a pretty decent price.

Anyone out there try this?

Im about to send a lower pulley to Mike at SHO source but this would be cool till the original comes back.

While bearings may "fit", many do not survive the engine. There is a lot more to a bearing then just fitment.

Like center of rotational force. Must be in center of bearing race.

While the above two posts are both generally true, it is also true that the need for force alignment with the bearing exists no matter what engine it is installed on, so it is highly unlikely that anyone will source a pulley that is not designed with that in mind. The issue of whether it will last in the SHO motor application as opposed to some Chrysler (or other) motor has to do with the linear speed of the belt movement and how that translates to the rotational speed of the pulley, and how that compares to the design ratings of the bearing, and to the quality of the bearing.

Since the SHO motor is likely to see higher rpms than the original design intent of some other pulley, it is certainly realistic that the adopted pulley may last a shorter time than it would have on the intended motor. However, since any bearing must be designed for infinite life, the differences in performance in alternative applications typically comes down to how well the seals are designed and therefore how well they do at keeping the lubricant in where it belongs. And that issue applies to any aftermarket replacement bearing as much as those adopted from other applications.
