Hi,
I inquired about this a while back, but my clutch is doing something
different than most diagnoses I’ve read on the subject of throwout
bearings going bad.
Mine is fine at idle with clutch disengaged, and with clutch engaged
fully. Works perfectly without the noise most of the time. I only get
the whirring noice as clutch is engaging, starting to move from a
standstill, and even then only under some load. It doesn’t happen every
time I start off.
I assume this is still a throwout bearing problem, but maybe just an
adjustment? Clutch only has about 20K miles on it.
Any info much appreciated!

No adjustment is possible. If the clutch is noisy when disengaging, it’s the
throwout bearing. Pretty simple to change. Might be worth changing the whole
clutch, if it is the original.

The clutch was replaced about 20K miles ago by a local shop. The bill
says they "removed clutch assembly and machine flywheel, and installed
new clutch assembly." Maybe they didn’t change the throwout bearing…

If they went to the trouble of machining the flywheel, I’d be amazed if they
didn’t replace the throwout bearing. But you never know, unless you do it
yourself ;o)

The following fix is a real hack, but it fixed my 80 900T for two years (10k
miles). My throwout bearing was making noise and the clutch was good but if
I replaced the bearing I was going to replace the clutch too, so I felt I
had nothing to loose. I used a can of spray chain lube with a long nozzle
to spray quite a lot of lube into the area of the throwout bearing, gaining
access through the little inspection plug. The lube foamed and worked back
into the bearing and fixed it for about 6 months when I repeated the
procedure. I pointed the car downhill and had to spray more lube then I
thought it should take but it worked until I replaced the car. The clutch
continued to work perfectly. YMMV

I am beginning to think I should be, but the clutch has been working
great for two years. That’s why I was hoping it’s simply an adjustment,
but from the responses I take it the throwout bearing is either good or
bad, no in between.
The whirring sound began about a month ago, only when starting from a
dead standstill, but it seems to be getting worse.
Thanks everyone for the feedback.
