pulley for 258

[kalve]

I am needing to find the small pulley that goes on a 85 AMC Eagle 258 engine. Its not the Idler pulley its the small one under it. Does anybody know what it is called an were I can get one at?

??  What's it turning??   Also need to know if its a serpentine belt setup or not, if A/C or not, and if A/C whether its factory air or American Air add-on.   If you have a way of looking at section 16.40 of the parts manual, you'll see what I mean.

There should be a diagram of the belt setup in the 'pedia.  I tried to look but I've forgotten my password.  I seem to remember that there is a tensioner pulley down near the bottom.

Its got factory A/C an ha people call it a tension pulley an its on the bottom. I think the guy said it it for the A/C.

Are you talking about the one that runs on the backside of the AC belt?

If so, those pulleys are not available, but you can replace the bearing in them by pressing out the old one and pressing in a new. I know of a few people on here that have removed the backside pulley and ran without any problems though.

sounds like it & yea get me that part # if you dont mind

The bearing is a 6203 type bearing, and can be found where ever bearings are sold. It is the same bearing used in the upper pulley as well, but the stock upper pulley bearing can not be easily changed because the front side is capped. Around $5-10 depending on where you get them.

That's 6203-2rsj or similar (that's the sealed one) NAPA carries a cheaper line P6203-2rsj too
