Pulley and bearing part numbers

I have a 2006 4cyl.

I need to know what the part numbers are for the bearings and or pulley with bearing in regards to the upper and lower idler pulleys.

I already replaced the tensioner pulley.

 

Check this out !!!

Here is the complete parts manual for your truck showing diagrams and prices as of Oct/2014

That does not seem to list the bearings...

 

Yup , you are correct , If Toyota parts , you probably have to buy the complete pulley just to get the bearing .
Only thing you can do is press the bearings out and grab the number off each individual bearing .
Are the pulleys still in good condition . A faulty bearing will wear down a pulley fairly quickly .
If you have time to wait , I am sure somebody has replaced individual bearings on the pulleys .
May take a bit before you get a reply

 

Yeah it looks like the pulleys are fine....just the bearings are starting to go I think.

 

Hope I am not hijacking the thread. I was wondering if anyone knew if the part number 166030p030 would work for the 2.7's idler pulley. I only ask because part number 88440-25070 appears to be plastic and the original in my vehicle is steel. The link I provided shows that it works in 2.7's.

 

I didn't have the time to wait....i ordered the pulley with installed bearing from rock auto. Since the pulleys on both of these are good I am going to get new bearings for the original ones...when I finally figure out the part numbers I will post them.

 

Typically you replace the pull as 1. You can proably find the specific bedding but it’s not worth wile.

 

You very well may be right...but I won't know for sure until I find out what the cost of new bearings will be. It might behoove me to have the rebuilt original assemblies and an old belt on standby in the truck for a JIC scenario...ill post when I know for sure.

 

it seems to be the original pulley was #88440-35140 which was steel?, and was replaced by 88440-25070 which should be the #2 bottom pulley. the upper #1 pulley was originally #16603-0p030 was replaced by part #16603-31040. im pretty sure the upper pulley has an unusual sized bearing and probably better getting the whole enchilada for $55 instead of playing around with bearing sizes/fitments, the other lower #2 in question may be able to get a replacement bearing if you can get the bearing size and reuse it
