On Thu, 29 Jan 1998, Aaron Ackley <hq@7arcom.army.mil> [note that I'm
guessing this is the correct address, as it came to me somewhat garbled
-- must be a tough day for the Internet!] asked me to forward this to the
list:
> Hey folks..
> I've been lurking for a while now, and though I don't have a whole lot
of knowledge to contribute, I *have* learned quite a lot just by reading
about other people's problems. Now for *my* problem...
> GT6 MkIII, comm # KF12142U > > I suspect that all GT6s have tranny
problems, it looks to me to be an inherently weak design. I have it out
and apart, on a nice clean bench, and I had ordered a bunch of 'common'
rebuild parts from VB. Before I took it out it sounded like a coffee
grinder in every gear except 4th.. and oh yeah, it is NON-OD.
> So anyway, it turns out that the needle bearings inside the end of the
First Motion Shaft (input shaft) have turned to a lovely silverish goo,
and the end of the Mainshaft had been spinning in the cup-end of the FMS
for some time.
> The damage does not look to terribly horrible, but of course I only want
to do this once, and that is a bearing surface. The problem comes in when
I try to find a new FMS.... VB sez they are no longer available. Anyone
know of one available for less than the cost of a new Lexus? It seems
that the older ones can be had, but not for the MkIII....
> I have entertained thoughts of having a local machine shop overbore the
bearing cup and harden it, to accept a larger (stronger) bearing, perhaps
having the end of my (otherwise fine) Mainshaft turned down a few
thousandths to help... or maybe have it bushed?
> Then I started reading (from the list of course) all about how a
late-model tranny from a Toyota Supra could possibly be made to fit... a
nice, new, smooth, strong five-speed sure is tempting.... Anyone actually
driven a conversion? As the car is 100% bone stock just now (and not very
valuable for it) I would like to avoid the cursing of any future owners
(not that there ever will be any future owners!) by ensuring that any mods
are fully reversible.
> Yes, I can be a bit verbose.. sorry. And thanks for any input *heh
heh*
