A Toyota gearbox is installed so it is highly likely that a modern
clutch (roller) bearing is fitted instead of a carbon one. It is
also likely that the clutch set up is different from the original.
A slave cylinder is usually adjustable by moving/shimming/clamping
it away from the clutch fork or by an adjustable piston rod. It is
imperative to have clearance between clutch pressure plate and
thrust bearing, being it carbon (especially carbon) or roller
type.<br>
The input shaft bearing is hardly the cause. It must be very worn
before it plays up as the shaft is also supported by the pilot
bearing. Very unusual and it makes a more grumbling noise, but it
could be a possibility<br>

<p class="MsoNormal"><span>Kees, I assume by clutch bearing, you
mean the clutch throw-out or release bearing. On a BJ8,
these have a solid carbon contact surface and do not move
other than in or out depending on the pedal motion. I
literally just replaced that bearing on a BJ8. I do realize
that there is much more expensive throw out bearing that
does utilize ball or roller bearings but I have never
actually seen one of these. </span></p>
<p class="MsoNormal"><span>I know of no way to increase the
pedal travel on a BJ8. The pedal to master cylinder is non
adjustable and the slave cylinder to clutch is also non
adjustable. </span></p>
<p class="MsoNormal"><span>When I mentioned, in an earlier post,
the input shaft bearing of the transmission - this shaft is
at engine speed with the clutch released, and motionless
when the clutch pedal is depressed, which allows one to
select gears without grinding them. Road speed has no
influence on the transmission input shaft. I had exactly
this problem on a vehicle (not a Healey) and that was the
problem and was solved by replacing that bearing. </span></p>
<p class="MsoNormal"><span>I certainly don’t know if that is the
problem in this case but, to me, it is the only logical
thing that is moving at engine speed (not road speed) with
the clutch released and the only thing that would be
motionless (relatively speaking) when the clutch pedal is
depressed.</span></p>

<p class="MsoNormal">The clutch pedal may have to little
travel before engaging, leaving the clutch bearing spinning
around with no or little load which can cause this kind of
noise.<br>
Try increasing the pedal travel slightly.<br>
