Help!

I have an '84 Westy w/ 170k (miles) and am getting about 10k on a
clutch (third go-around).  First one went about 80,000 -- replaced
disk, plate, pilot bearing, throwout bearing. Second one replaced at
12,000, included a flywheel this time.  Third time, dealer out of
ideas, just did the standard stuff.  Ready for the fourth one now. (!)

Symptoms are: Everything silky-smooth when first replaced.  Within a
month or so, start feeling a very slight vibration in the pedal.
After a while slight juddering begins on rare occasions (more on that
below), then gets progressively noticeable until it's routine and
severe by around 12000 -- coincidentally the limit of the dealer's
warranty.  Seems to be worse in reverse and possibly when turning a
corner; definitely worse on hills, of course.

All of this is strongly affected by temperature, and I believe it's
the transmission temperature that counts.  In cold weather all is
smooth; but not in hot weather.  An hour or so on the highway will
aggravate it, and shutting it off and waiting ten minutes after that
will make it worse.  I haven't seen the motor while this is happening,
but it sounds/feels like it's about to jump out of the box.

Any thoughts?  Dealer particularly puzzled by it being worse in hot
wx, he expects the opposite.

Thanks and regards,
david
