So i expected to be able to replace the bearing in my 70mm pulley. Grainger sells the, for about $11.
It turns out the previous owner had replaced it with a Dayco unit, and there is no record of the part number. Which has the bearing already molded into it. Cracked it learning
I am trying to find a local souce for the pulley, as we know autozone, advanced, pepboys, napa does not have the part listed. I was able to find one of similar dimensions from Gates at a wholesale place, however it is too narrow.
the dimensions of the installed dayco are 70mm x 29mm with a 17mm bearing hole. Daycos website lists none that are exactly the same. I must be measuring incorrectly. The local shops are unable to cross reference.

Does anyone have a part number for that pulley from a chain supplier? There is not an O'Reillys near me.

Thanks for the help.

I did press out the bearing in the 80mm pulley and i think that solved my scraping noise. Credit to who ever advised that you can not rebuild the bearings, regardless of how they feel.

Thanks for that. For some reason I could not find that.

In either case, i was able to get a Gates 36275 that fits. The bearing is not in quite the same location, so I had to reverse the pulley and use the OEM bushing as opposed to the one that came with it. In order to get the pulley to line up withe belt.

thanks for the response.
