Does anyone know the torque specs for bolting down the 968 seat?

Are they supposed to be replaced when the seat is removed with new bolts?

Thanks!

I think they're M6 going into delicate sheet metal so maybe 7 ft-lb? I usually make them snug just past hand-tight and re-used the bolts / washers. Also important, don't strip them.

Thanks, looked through the shop manual, see no mention in the 944 or 968 books.

I hate winging it, I always strip things

Loctite?

i'm pretty sure the bolts that hold down the tracks that the seat slide on are substantial bolts as they are "structural' in that they keep the seat secure in an accident. I think you'll find that they go into an area of the unibody that is strengthened to secure a structural bolt.

When you can't find a specific spec, you have two choices. If you have a manual, you can look at the torque charts for the same size, grade and same pitch bolt. The other option is to get the info from on line sources from bolt manufactures, or from engineering sites such as www.imperialsupplies.com The torque chart is under the Resources Tab, and then Fastener Torque Charts.

6mm bolts = 6 ft. lbs., or 72 inch pounds. No more.

Actually most cheeseheads with a 6mm head are in the 17-22lbs/ft range so that is what I would recommend. These are not your m10 nuts, but cheeseheads that have a 6mm receptacle. A good comparison would be the intake manifold bolts. Check the factory spec for those.

And I thought this was going to be "What do you think your butt-torque is?" thread.

Actually, it looks like the seat rail bolts are M8 so I'd torque them to a similar spec as one would for steel bolt into aluminum since these are proven to strip. 16-18 ft-lbs.
