Default Torqu Spec Frustration

Man I picked a bad week to quit sniffin glue! I have Adrian's book, and Bentley "Technical Data Witout Guesswork" and they are pretty lacking for torque specs. Can someone please look up the following, so I can write them down. It is a good thing I did not run out of firewood!

Spark Plugs
Front Tranny to Body Mounts (6)
Rear Engine Mounts
Tranny to Engine (4)
Shift linkage bolt.
Pressure Plate to Flywheel
Sway bar to link (2)
Sway bar to body (4)
Upper sway bar link
Brake Caliper to Hub

Thanks,

Not sure if I got all of your requests mapped correctly to the terminology in the book. If there is anything outstand we can try again:

Code:
Nm (ftlb)
25-30 (18-22)  Spark Plugs
46 (34) Front Tranny to Body Mounts (6)
85 (63) Rear Engine Mounts
85 (63) Central tube to transmission
75 (55) Double clamping sleeve to central tube
42 (31) Drive shaft to transmission flange
        Tranny to Engine (4)
18 (13) Shift rod (fit bolt) - secure with Loctite 270
        Shift linkage bolt.
        Pressure Plate to Flywheel
23 (17) Stabilizer to side member
46 (34) Stabilizer to stabiliezer mount (hex head bolt)
35 (26) Stabilizer mount to wheel carrier and stabilizer (ball joint)
        Sway bar to link (2)
        Sway bar to body (4)
        Upper sway bar link
85 (63) Brake Caliper to Hub

Alan, the torque spec for the drive shafts to flange is incorrect for your bolt size. You need 59ft/lbs.

Geoffrey, is that because its a RSA? Would 31/lbs be correct for the rest of us?

No, there are 2 bolt sizes for the 964 series car, one is an M8 bolt that is torqued to 31ft/lbs and the other is an M10 which is torqued to 59ft/lbs. I don't know what models use the M8, it might be the tiptronics, I just don't ever see them. A Standard C2/RSA/RS/Cup/RSR all use the M10 torqued to 59ft/lbs.

My data came from the Porsche 911 Technical Specifications "mini" book WKD 423 920. Torque specifications for removing and installing engine/transmission unit, page 108. This is within the 911 Carrera section.

On reviewing the Shop Manual, Volume 2 Transmission, I've discovered the same "specification" for the drive shaft to (front) transmission.

Perhaps that's the spec that is quoted in the mini book?

My apologies for the mis-information. And, thanks, Geoffrey, for correcting me.

Cheers,
Dave

Thanks also for pointing this out. Time to get back under the car and retorque!
