rockauto.com will do a pair of new dayco brand idler pulleys complete for about £50 delivered, I fitted some to mine 10 minute job and quietened the engine down (old bearings dead).

:?: :dont know: why would you use a more expensive non standard bearing?
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Just a case of pressing out the old and pressing in the new..
Freezing the bearing and heating the pulley may help.

Hi thanks for the tip here.
Does anybody you know if the bearings above are the correct spec for both idlers, and the tensioner.
I have a 996.2 C4 manual
I was previously looking at the Hamburg ones on design911 for £50 each, these all have different part numbers, so assumed there was a difference.

Many thanks
The bearings can only be replaced in the metal pulleys.
I can't remember how many are metal, 1 maybe 2.
The plastic moulded over the bearing cannot be replaced.
The bearings I specify are the correct spec. Identical to originals for the metal pulleys.
Very simple to press out and in.
rockauto.com will do a pair of new dayco brand idler pulleys complete for about £50 delivered, I fitted some to mine 10 minute job and quietened the engine down (old bearings dead).
Or £18 each shipped? For the same FAG / SFK bearings hat Porsche use..

3, 8 & 7.
But check you don't have the newer type plastic moulded in place of these.

Hi. Just had to replace one of mine, didn't see this until after I had bought one. Quick measure up and the bearings are the same in the turbo. I'm going to get a set in and replace the others during winter
Thanks Neil :thumb:
