Brian,
When did the squeal start? Did you recently replace the pressure plate?
Perhaps with a Borg & Beck with the "cranked" fingers?
Many of us 6 owners have been through this very same annoying thing. It's
those cranked fingers.
Randall's statement about preloading will work as it does for many, but I
don't think it's due to TO bearing changes. Here's why. I took an OLD B&B
pressure plate out of my 250 (straight fingers)with an OLD RHP bearing which
worked fine(no squeal). I installed a NEW B&B pressure plate & driven plate
with the OLD RHP bearing. It squealed. Hmmm...scratching my head...it
didn't before...only change was the pressure plate & driven plate. So...I
try the Gunst bearing...doesn't squeal for about 1 hour then it squeals. I
did NOT preload the bearing.
So I tell a buddy of mine who's going through the same thing. I tell him
to buy a Sachs Pressure plate...straight fingers. Got it through British
Parts Northwest...pretty cheap 126 including a new driven plate(NFI). He
did NOT preload AND reports NO squealing after thousands of miles. You tell
me...have I done enough experiments? I didn't feel like pulling my gearbox
AGAIN after all this sooo...I deal with the little crickets inside my
gearbox.
Cheers,

Subject: [TR] TR6 clutch engagement squeal?

This is probably confirming the obvious, but I'd like to hear from the List
if
my suspicions are correct.
I now have a high-pitched metal-to-metal squeal when I just start to lightly
press on my clutch pedal. The squeal quickly disappears when I press the
clutch pedal all the way down. I've traced the noise with a stethoscope to
the clutch actuation lever/bell housing area. The clutch release bearing
seems to be the obvious culprit - which is a pisser since I only replaced it
and everything else in that area two years ago.
Before I once again yank out my tranny, does the List have any advice?
Assuming that it is the release bearing, are there better ones to use - or
better installation techniques - to avoid having this happen again so soon?
Thanks much in advance,
Brian Lanoway
