John, I might have a spare pilot bearing (brand new), I will look for it. In addition, I have the original pressure plate and throw out bearing out of my '87...with about 40K if you need them for any reason. Not sure of the compatability with a '79. You know where to find me...

John, I am sorry you are having trouble with the clutch, it worked like a charm for me in my 87 with 379lb/ft of torque at the time. I have a pedal cluster if you need one.

The above two post just shows the camaraderie within Pelican! Thanks too you both. I think I have it figured out... at least I hope. I finally had the time to sit back, and trace my steps from the rebuild. I believe I torqued the clutch down too much, which would explain why at hotter temps the clutch got worse(expansion). that would also explain why the outer ridge of the flywheel was so worn down (over torqued bolts adding pressure on the outside). I will also clean and check the throwout bearing, and take a wizzer to the flywheel.

If that doesn't work, I have delayed the inevitable. Its time to replace the flywheel, and all other clutch parts that were used as a summer daily driver for the past 29 years. I will let you all know the outcome, after I get my WUR back from Leask

P.S. I got the chance to check everything on the rest of the engine, and it is within spec, and handled 1K post rebuild miles like a champ!

I'd check the flywheel and clutch plate surfaces for warping now. It looks like there was some overheating/galling on the plates, and if you overtorques with the heat generated you probably have some warpage. It's pretty cheap to have them surfaced and it may save you another pull (as fun as that is.. )

Thanks Chris. I am going to take everything down to the local machine shop, and have everything measured just to be on the safe side.

...from the workshop manual: clutch bolts torque 2.0-2.5 mkg, (11-18.5 ft lbs)
...and from the pocket spec book 2.0-2.5 kpm, 10-25 Nm
hopes this helps

John I have a excellent used flywheel If things dont work out at the machine shop. When i did my clutch i couldnt believe how small the torque spec was, the overtorque sounds about right.

Of all the torque specs on the 911, the flywheel bolts and head-studs always feel "too low" for me. I do what Stuttgart says, but it just doesn't feel right.

Thanks for the torque specs guys. I know I torqued it down a whole lot more than that. I have no idea where I got the torque number from. Must of misread the manuals... I am just glad my one mistake of the rebuild wasnt anything more serious.

H20cooled7: Thank you, and I will let you know if I need a replacement.
