Summary

Longer downtimes were nothing unusual after the corona pandemic, but surely that can't affect a Porsche 911 (Type 993)? To be on the safe side, the author of this article checked the V-belts and this ultimately led to extensive maintenance activities that were unforeseeable, but in retrospect quite instructive. This report, which also contains three videos and lots of pictures, tells you exactly what happened and who was involved in the extensive operation.

This article contains the following chapters

Removal
Alternator
Assembly - first attempt
Fan wheel - for the first time
Fan wheel - for the second time
Fan wheel - to the third
Assembly - second attempt

Preview (beginning of the article)

As is the case when a toy has been missing for a long time - due to the coronavirus, my air-cooled Boxer had also been out of action for a while. So, I thought to myself, you need to get back into the garage. It's time to look after the ten-year-old V-belts anyway. The 993 Carrera has three of them. So I quickly unscrewed the pulleys, using the same technique as in the Beetle since 1948, inspected the belts and, out of boredom, played around with the fan shaft, which was now free of belts, to say "conscientiously checked the radial play of the alternator". Clack-clack-clack. Heavy noises. Asked Professor Kuno in the museum workshop how much play is allowed? Short statement: "None at all, at least none that you can feel".
