I'm trying to find the p/n for the three studs that screw into the fan bearing hub. They are keyed for an allen wrench in the front of them. One of mine sheared while removing the nut on it.

I would have thought that PET page 105-00 would show it, but I don't see it in the illustration.

You can see them in the photo of post #6 (with the nuts on) here-

Any guesses?

Thanks!

Nick,

Why not make your own stud or use a 6mm bolt? When I removed my fan a few years ago, one of the studs looked questionable, so I made my own by cutting the head off of a 6mm bolt and I screwed it into place with a little locktite.

when you put them back in put a little anti seize on them

"While you are in there", think about the RS pulley upgrade. The fan will spin the same speed as ever. The alternator will spin with the fan. Nice single-belt system like the early 911s. I have noticed the AC fan speed droop just a tad at idle, but so far no complaints.

Thanks all. I found a photo on another thread where someone had replaced them with regular allen/hex-head bolts. That could be what # 12A in the PET is showing. A quietly updated part?

These studs have a strange flat mid-section that is a larger diameter than the threads (rather then smaller diameter like a normal stud) that looks like it is meant to give a more precise fit. Though it looks unnecessary in the end.

Springer - I considered the RS pulley, but I don't want to worry about charging. Especially in the winter, say in traffic: at idle, heat on, headlights on, brake lights on, radio on, C4 pump kicking in to occasionally build up pressure, etc.
