re. pressure plate bolt torque? (shouldered vs. nonshouldered)

Ken,

The shouldered bolts are what you wil gett from the dealer and consist of a
washer sized base(shoulder) rather than a lock washer.  I assume this is to
provide more even load distribution for the fastener.

If you are re-using flywheel fasteners (not recommended) and they have a
washer or no change in size of the head, then they are not shouldered. The
pressure plate to flywheel bolts are usually not shouldered.

Oh, make sure you have the correct flywheel and Pressure Plate torque specs
as they have been known to be mixed up in the Bently.  The flywheel to
crank should be around 75 ftlbs  and the pressure plate more like 20(I was
able to torqu mine very carefully to 30, as I didn't find the correct
value).  I have known of several instances of stripping the pressure plate
bolts when the wrong specs were followed.

[Hello List,

I need to bolt on the clutch pressure plate for my 5kcstq.

The Bentley mentions two types of bolts, shouldered and non-shouldered,
with different torque specs for
each.

I'm not sure what they mean buy "shouldered".  Does this mean a section
without threads at the base of
the bolt?  That's the best guess I can make.

It can't mean the "head" of the bolt, right?  I mean, any bolt that is
going to be able to hold the pressure
plate on is going to have a head on it.

Too bad there's no picture of the two types of bolts.

Any help is appreciated.  I don't want to use the wrong torque spec.

Thanks,

Ken]
