Replacing the Tensioner Pulley - V6

[sutto]

To undo the bolt do you turn to the left or right because somone else told me undo the bolt to the left

 

[BOGANV8]

The bolt is a left hand thread so undo clockwise.....

Read this wrong....BoganV8 is correct.

You dont have to press the bearing out to read the part number. Just take it off the car, degrease it and you will be able to read it from the back. Its stamped into the seals in fine print.

Of the three pulleys on an eco, two are the same and one is unique.

Common bearings too.

Or pop into your local Auto shop and have a look at some new ones. Read the bearing numbers.

unless it's an aftermarket metal pulley having a bearing number is no help, the stock plastic one are a molded 1 piece unit, pressing the bearing out will destroy it.

Correct

The replacement bearing for the aftermarket steel pulleys is a 6203-2RS I believe. I can double check that one if required.

I still think the reason that these fail so quickly is the fact that they use a single row deep groove roller bearing which isn't designed to carry a vertical load like this. You really want 2 bearing side by side to ensure that the pulley runs true.

That's a great idea.

Twin high speed bearings well spaced apart in machined pulleys would really help hold everything square and true. Much more so than now.
