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

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

long-distance ones.  A photo of the old clutch disc is attached.

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
