There is a discussion going on on the triumphs list regarding whistling
throwout bearings. It looks like I have one. The consensus seems to be that
the bearing should have a small amount of preload. Some kits apparently come
with a spring and attachment strap for this purpose.

The drag of the bearing to it's shell is simply greater
than the friction of the clutch fingers to the bearing
shell. Did the bearing you install, spin freely
after installing it on the carrier? It may be binding
a bit.
You can put a light return spring (red HELP paks at local
auto parts stores) on the arm so it stays lightly pressed against
the fingers so the bearing will rotate with the flywheel
or just slightly off...your preference.
Greasing it... the grease will sooner or later simply 'leave'
the area due to centrifugal forces.
Or just learn to live with it for awhile. Once the 'finger'
wear just a bit it will quiet down. (hopefully??!!) :-)

> I just completed a mechanical rebuild on a 1973 GT6. I installed a new
clutch, pressure plate and throwout bearing. When the clutch is fully
released, the throwout bearing makes a chirping sound like a bunch of
deranged crickets. When I press in the clutch even slightly, the noise goes
away. In all my years of working on Triumphs, I have never run into this.
It seems to be caused by the throwout bearing lightly touching the fingers
on the pressure plate. Has anybody else ever encountered this? Would
lightly greasing the face of the throwout bearing fix it?
