the damn thing SNAPPED! [was: Re: pressure plate bolt torque? ]

[auditude at get.net]

Huw,

I think you called it.  I have the older, single book Bentley.  I can
see that the stupid torque spec for the center bolts says only 18 ft
lbs, with an arrow pointing to the bit bolts for the flywheel.

The Bentley has an arrow pointing to the little allen bolt I broke,
and lists the information I posted.

Looks like my Bentley is broken.  Damn thing.  That's the last time I
buy a used obsolete Bentley off some local dude. :-)

Had I studied the whole page, I would have seen the typo.  Duh,
shouldered vs. non-shouldered makes a helluva lot more sense for
those bolts.  I've yet to see a shouldered allen bolt.

Well, I guess it ain't so back.  I think I probably undertightened my
center bolts, so it's all good that I didn't try to drive that way.
Not to mention put it back together to have to take it apart again.
One 6 month clutch job at a time, please. <g>

Damn.

Thanks!

Ken
