Hi Ted,

Yeah, sounds like you definitely need a new clutch input hub. If you
don't already have 4mm deep splines, now may be the time to consider it
(if your budget allows).

As for needing the special tool, someone else will have to chime in. I -
for one - have the "far superior" 4-speed transmission that uses a
simple little snap ring to keep the clutch hub in place. :> Personally,
I have my own little conspiracy theory about Guzzi using the four-pin
nut on subsequent transmissions just to sell more special tools. You may
want to try using a deep well socket of the same diameter, and
grinding/filing it down to create your own special tool. This would
probably work pretty well as I believe the torque spec for this nut is a
manageable 50 - 57 foot pounds.

As you've mentioned, it is easier to replace the clutch components with
the engine stood up on end. But, it is doable (especially with an old
clutch hub to line things up) to do it with the engine in place. Tedious
practice...trial and error...tedious practice! :>

Best of luck.

Okay I began to reassemble my clutch when I noticed the problem that
caused
me to dissasemble the thing in the first place. All the clutch
components
are fine, but the transmission input gear looks like it has had the crap

beat out of it. So I guess I'm gonna order a new one ($95 bucks phew)

My question: Do I need the ring nut tool
(http://www.mgcycle.com/tools.html)
to get out the old hub? It looks like the PO may have tried to get it
out
without success, the nut in there looks a *little* bit mangled. I can't
think of any other way to get it out easily, but I hate to spend $36 on
a
tool I'll probably only use once.

My comment: It is beyond me HOW ON EARTH you guys would ever assemble
the
clutch with the motor still in the frame. With the motor on its nose, I
had
a tough time keeping the springs in place, not to mention lining up the
intermediate plate.
