I'm looking for the bearing number for the AC idler pulley.

If you've replaced yours and have your old one laying around, or if you have replaced the bearing in yours, please, I'd love to know the bearing number for it.... thanks.

 

Actually.... I have a like new pulley, and the old one siting in my glove box, ill be home tomorrow night, and can get you the number, otherwise, ill sell it to you?

 

Don't even know if I need it yet....that is extremely generous, but really, if you could get the part number off the bearing, that would be awesome.


Heard a squeek on start up yesterday, timing belt, water pump and all accessory belts new.....just thought it was the most likely culprit.

 

New does not mean tight, however. I swapped all mine when I did the TB this spring, and I thought I had them good and tight. My alt belt needed some more turns after a few weeks to cure a squeak. Don't assume your belts are tight until you check. They should all be checked after running-in after replacement. (not TB, of course)

 

The guy who did my work was a 25 + year MDT, who has done hundred of timing belt changes on the 3.4L.......that being said...... I checked the belts.

 

I see a few numbers. on the inner metal part
6203/12.203

one the dust cover 6203lu


looks like itd be way easier to just buy a new one.

 

ask local parts house for a double sealed 203 bearing

 

Rebuild procedure here...

There are apparently two different options.
One is OEM and the other is dealer option A/C. Sorry, don't know which is which.
The above procedure should be similar for both.

6203LU =
12mm thick
17mm bore
40mm outside diameter

6301-2RS=
12mm thick
12mm bore
37mm outside diameter

 

Hmm thats odd, I THINK this is the pulley i got from advance auto. AC is factory, this is a 99 limited. Those numbers are off the same pulley. Mine doesn't look like the one in that link. bearing pressed in, no snap ring. same as the one i took off the truck

Tell ya what, ill send it to you for the cost of shipping if you want, it was on the truck about a month or two until I got the whole tensioner system from toyota due to me breaking part of it being dumb.
