Idler pulley bearing part number

[wckdvnm]

Does anyone have the part number for the stock idler pullies. I’ve searched it and haven’t found anything; I will mention I suck at using the search function. I’m going to press in some new bearings while I am putting in a new water pump.

Upgrade to Metco or Billetflow idlers if your still on stock idlers.

This is for the inner idlers. The outer idlers will be changed to better ones in a few months

Same pn. 203 bearing. Oreilleys had National which is a good brand.

When I bought my Vert (had 76K miles on it) one of the first things I did was replace the bearing in the idlers inside and out.

Although I put Metcos on my coupe I'm a FIRM believer that the idlers explode because the bearings go bad and lock up causing resistance. That's just my theory, but my vert has the stock idlers with new bearings and zero issues.

Here is a bearing that I used on my Vert:
