I know people have made adapters for generator heads so that they can
be
used with a belt and pulley or direct coupled. I would like to try
running one with a 6 hp diesel engine. This may be a way to use
generators ends with the Tecumseh engines, since no one else make an
engine with the proper taper to fit the gen heads. At least if they do
I
have never heard about it.

I'm not quite sure what you are saying but in order to use a generator head
from a tapered shaft engine a LOT of machining would probably be required.
And it sounds like you know how to do it. Are you thinking of something
like a tapered shaft that bolts onto the rotor/field in much the same way as
it is normally done? Would this basically be about the same as using the
crankshaft? Plus you would still need a way to mount the stator so would
you be cutting away the engine case, or keep the engine more or less in tact
and just reworking the opposite, non PTO end? I don't recall ever hearing
of anyone actually doing this so I'd like to hear more about it. Plus, if
you have any pictures...

I can't swear to this but I THINK the taper on my Honda GX270 is the same as
the taper on my Tecumseh HM100, except the shaft is longer on the Tecumseh.
When I replaced the gen head with a "generic" head on the Tecumseh I had to
use a 1 1/2" spacer to accomodate the longer shaft. I'm pretty sure the
same head would bolt directly onto the GX270. OTOH I do recall attaching
the generic generator head to a 4 HP Honda engine, just to see how many
watts it would produce (I got about 2200) so maybe the taper is smaller....


Caution. Many portable generators (and some that are not-so-portable)
have only one bearing on the generator rotor. The other part of the
rotor
is supported by the engine crankshaft. It would take a machine shop to
make an "adapter" to swap engines for most of those units.

Further; unless you engineered an adapter that incorporated a bearing,
belt driving one of those generators would be impossible.

That's exactly how they do it. The housing has no bearing on the engine
end.
Yet some have a place for a bearing, only the shaft is made wrong. I have
a
lathe and mill and once I figured out what was needed to do the job. It
might take less than a day depending on what had to be done.
