Does anyone know the bearing # for the serpentine idler pulleys?

ps.. just the bearing # not the pulley/bearing assembly part number.

thanx

The ones on the timing belt, or outside on the accessory belt?

I don't think they're offered separately from the whole pulley assembly, but I have the old ones just pulled. You're welcome to have one and you can pull the bearing and take it down to the local bearing dealer so they can measure it and look up a replacement.

? Your's for the cost of sending via USPS.

Accessory belt. They look to be a standard 6203 2rs. If someone could confirm this it would save me from pulling one off.

Thanx

Why would one bother with trying to replace just the bearing portion of the idler pulley assembly? I assume that it can be done with the proper tools but the whole assembly costs all of $19.99+applicable tx or ca. $40+tx for the 2 needed at NAPA or maybe less if you can get a mechanic discount.

That is assuming you are referring to 5066938AA for which you can substitute NAPA 36101 (just lose the big washer) or Precision Parts EP101. This is a rather common assembly.

Because the bearing in the Napa part is offshore junk. I want to split the halves and put in a quality bearing.

Ok. I don't know the size then.
