I'll leave others to answer your questions  ... ..but ...
My experience has been that resurfacing the flywheel is an absolute must if
you are doing any clutch work.
There is nothing that contributes to clutch shudder as much as a very
slight imperfection on the flywheel friction surface.

We're not sick of hearing your troubles, Simon. We all learn from 
others' problems and solutions. Please keep us informed.

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 
/and/ 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.

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). 
Last time I had my BJ8's gearbox out I didn't replace it, as the bearing 
appeared to be holding up and I mostly drive highway miles in it. As for 
the disk and cover plate, unless they're almost new that's an automatic 
replace, along with the spigot/pilot bush. If fairly new, I believe the 
cover can be turned--like brake rotors--but I'd probably install a new 
disk regardless. With Healeys, with no rear main seal oil on the disk 
will cause nasty judder, so any oil or burn spots is automatic reject. 
If the cover plate disk has any bluish burn spots I'd likely chuck it.

Alignment tools are handy, but if you're mating the engine and gearbox 
on the bench you can use the first motion shaft.

In January 2014, I removed the gearbox and overdrive from my BJ8 to fix a
problem with the O/D slipping (low oil pressure) and a bad clutch judder in
reverse that I had put up with for too long.

I replaced the clutch release bearing for convenience and because I already
had the new one in hand.  The new bearing carbon block from Moss Motors
measured 10/32" thick.  The old one (also Moss Motors, installed September
1997) measured 9/32".   That was only 1/32" wear in 80,534 miles, but mostly
long-distance ones.  A photo of the old clutch disc is attached.

I currently have my BJ8 tranny out.  I have had the OD completely completely rebuilt and having a few well worn tranny components replaced.  The worst part of taking out the tranny and rebuilding is getting the old pilot bush out and  a new one installed.  If anyone thinks the Healey clutch is a tough job, I invite you to replace clutch components in an E Type.  The engine must be pulled with all that has to be disconnected.  I'm in the process of removing mine now. That carbon TO bearing rubbed itself down to metal:):)

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.

When I was learning to drive in a manual transmission car, my dad emphasized
to NEVER hold the clutch down while stopped at a light, etc.    That's a
lesson I learned well.  No sense wearing out the bearing for no good reason.

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.

With all the chatter about the throw out bearing I am surprised no one has
mentioned the Denis Welch replacement. One caveat is you have to permanently
modify the cover plate by removing the center pad. The carbon throw out
bearing always seemed odd to me but I have no knowledge of why it was
designed that way. Could it have been state-of-the-art back in the day?

Subject: [Healeys] Clutch

You will all be as sick of hearing about my OD as I am of lying underneath
it. I've decided to kick the whole thing into touch. I'll whip out the
gearbox (hah!) and drive it complete up to OD Spares who will sort it out
while I wait. Even if I have to wait all day. Beats making the round trip
twice.

Which leads me on to thinking about "what else to do when I'm in there"...

1)      I don't know how long is a piece of string, but is there a mean
average duration for a clutch in terms of miles? Not driven hard, just
driven.

2)      I see that people quite often sell the clutch as a kit consisting
in: the plate assembly, the cover and the release bearing. I thought that
one replaced the latter every time one got near it and that one replaced the
plate as and if needed. But - I thought - the cover is just a hunk of iron
and didn't ever need replacing. Am I right in any of that??

3)      Tools..I see a great variety. In shape, design and in cost. Broadly
speaking there are variations on A or B. The former seems elaborate and not
suited to someone who hopes to only ever change one clutch in his life. But
B is so very different from A that one wonders if it can do the same job..

 

Now to battle with the gearbox. Oh joy....

The DW release bearing looks to me to be an adaptation of what is used in
the TR6.
My experience with those has not been good. Back in the day we used to
replace lots of TR6 pressure plates because the bearing had tightened up
and then worn off the pressure plate fingers.
If you must modify the clutch operating system the go whole hog and fit a
concentric slave cylinder
Lots of work but bullet proof.
I fitted one to AHX12 about 18 years back after the Toyota 4 speed type
failed in Newfoundland.

Tom,

=20

In cases like this I have used the old engineers=E2=80=99 trick to =
=E2=80=98hydraulic=E2=80=99 the pilot bearing out. =20

Fill the cavity behind the bearing with oil, insert a =C2=BE=E2=80=9D OD =
drift into the bearing, give it a solid belt with a hammer, and it =
SHOULD pop out. =20

This procedure has never failed me.  I say SHOULD, as it may not have =
worked for you.

And don=E2=80=99t wear a good shirt whilst doing this.  =F0=9F=98=8A

I currently have my BJ8 tranny out.  I have had the OD completely =
completely rebuilt and having a few well worn tranny components =
replaced.  The worst part of taking out the tranny and rebuilding is =
getting the old pilot bush out and  a new one installed.  If anyone =
thinks the Healey clutch is a tough job, I invite you to replace clutch =
components in an E Type.  The engine must be pulled with all that has to =
be disconnected.  I'm in the process of removing mine now. That carbon =
TO bearing rubbed itself down to metal:):)

In January 2014, I removed the gearbox and overdrive from my BJ8 to fix =
a problem with the O/D slipping (low oil pressure) and a bad clutch =
judder in reverse that I had put up with for too long.

=20

I replaced the clutch release bearing for convenience and because I =
already had the new one in hand.  The new bearing carbon block from Moss =
Motors measured 10/32" thick.  The old one (also Moss Motors, installed =
September

1997) measured 9/32".   That was only 1/32" wear in 80,534 miles, but =
mostly

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 =
and 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.

=20

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).=20
