Yeah it *is* a weekend, and a great one for being outdoors here in
the northeast. I set a new world's record today, at least a record
for me. Pulled out the GT6 gearbox and clutch *and* re-installed
them within 8 hours. Okay, so I haven't snugged up the bellhousing
bolts yet, nor installed the interior bits.
Of course, the purpose of this exercise was to find the cause of the
chirping TO bearing. The pins I mentioned in my earlier note (which
Nigel had suggested were the probable problem) were the protrusions
that operate the TO bearing. They did not even show significant
wear. The bearing spun freely and had no apparent roughness. The
bearing holder had a well-formed notch to prevent it from spinning on
the tranny input shaft. Inotherwords, I could find *nothing*
apparently wrong. I did observe that the clutch arm and bearing
holder are easily dislodged when the whole thing is manhandled back
into the car but I don't think that was a problem.
I removed the pressure plate and clutch disk just in case they had
some recognizeable problem. Nothing, except that the mounting bolts
were far looser than I would have expected. Ahem, I wonder who
torqued them on re-assembly??? I'd say "Doh!" except that I know I
torqued them properly. Why would they have loosened up so quickly,
or at all, I wonder? Tomorrow will mean final re-assembly, and a
test drive! With luck there will be no chirping.
I'm still puzzled about the noise. The GT6 TO bearing is supposed to
be in constant contact with the finger springs. JJ at RaceTune had
said that a bad tranny input bearing could make such a sound, but I
can't see how. I'm open to suggestions.
Tanks in advance for any wisdom.
