Coverage and how to read this overview

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.

POST 1 / ORIGINAL POSTEROriginal post

The super charge whine of my 996 is starting to bother me, especially since I don't have a super charger. So in my investigation I have identified the source as the alternator. I know it's not hard to swap, but functions perfectly. I see a tool for removing the pulley. It is possible to swap out the pulley without removing the alternator. This is the first thing I could not find I good write up on.

POST 2 / ORIGINAL POSTEROriginal post

Never mind. I just realized what a stupid question that was.

POST 3Original post

Before you incriminate the alternator, have you checked the idler bearings? Just slip the accessory drive belt off .Run the engine briefly to confirm that eliminates the noise. Rotate each Idler pulley to feel for wobble and spin for a noise check.

POST 5Original post

I just bought the 32 spline tool on Fleabay for $2.50 inc shpg -from China !I already have the T50 torx. You can get an Impact Torx set (long) from Harbor freight for $10. You can get a comprehensive alternator tool kit for less than $20.

This is a source reference. Confirm exact model applicability in the original material.
