Thanks, Steve.
Thanks to that release bearing design I got into the habit of shifting
into neutral at stoplights (instead of just holding the clutch pedal
down). I think it's a good habit overall--issues getting back into first
notwithstanding--as I've had my foot slip off the pedal on occasion.

<p class="MsoNormal" style="margin-bottom:12.0pt">As for clutch
longevity, there
are several significant variables: (your) location, type of
driving, driving
style, etc. For example, if you DD your car in San Francisco,
I wouldn't expect
a clutch to last 50K miles, if that long. If you mostly drive
highway miles, I
think 100K is easily doable; I traded my '08 Mustang in at
124K miles with
original clutch <i>and</i> brakes. Although I've been driving
manual cars for
over 50 years, I still don't feel I've 'mastered' them (like
landings in
an aircraft). Dump the clutch too quickly and you'll increase
longevity--if you
don't break anything--at the expense of smoothness, be very
delicate and slip
it too much and you won't get 'normal' longevity. Actually,
IMO Healeys are
relatively easier to drive well, a properly set-up clutch with
a Healey's
torque makes smooth starts easier; my '19 Mustang is
high-strung by comparison
and I still manage to stall it occasionally.<br>
<br>
The release bearing can be problematic as, unlike a true
bearing it's a known
wear item. I heard a while back there were some low quality
parts going around
that failed within a few thousand miles. I'd say if it's more
than one-third worn--anyone
know the original thickness of the graphite?--I'd replace it
(again, depending
on driving circumstances). <br>
