Quiet, quiet!

Everything has gone very quiet and we haven't had a posting for
ages. There has been some very interesting postings on the South
African and American Syncro sites about decouplers regarding
increased fuel consumption and increased wear of some components
when decouplers are used. Since a number of us are waiting delivery
of Bernd Jaeger decouplers, this is of high interest.

I will precis the information and repost it on this site shortly.

In the meantime, I wish all Australian Syncronauts a happy Christmas
and a good 2005.

Les,
Can you cut and paste the information to this group as I am having
trouble with the yank site. They have too much security in case the
Russians get some syncro information. Yahoo sucks!(Yanks suck and so
do IT people too)
Speaking of decouplers, has the group decoupler purchase arrived yet?
What did they cost?

I hope you don't have the experience I've had.

I bought the German decoupler in 2004, through Fast Forward, via Jorg
Bartz.
God knows who makes them, I think they all come from the same place
and why the
people who make don't sell them directly via internet I do not know,
but that's
another one of life's mysteries.

Short story is that the gear that goes on the output shaft won't fit
on to the splines. David Marshall at Fast Forward tells me to just
hit it harder but
there is no way it is going to go on. I send it back to Fast Forward,
he assures me that
he can smack it on to his gearbox, and months later I get the gear
back.

I don't understand why won't fit. Maybe the broach that is used to
cut the splines in the gear was worn down, or perhaps it has
something to do with the
output shaft, which possibly is of recent manufacture seeing as how
the gearbox I
have is a VW factory exchange (Austausch) box, dated 2001. It's hard
to believe VW
can't maintain manufacturing tolerances though.

Upshot is that I need to get the gear modified somehow so that it
fits as nicely as the existing sleeve. An engineer suggested using
hone stones to
modify it, but another has said that bead blasting is the way to go
to relieve it a bit,
which is what I'll try. But it means I have to take the gear and the
transmission in to
him so they can check it for fit as they bead blast it. More hassle.

When the decoupler kits do arrive for those guys getting one, I'd be
really interested to know what the fit of the gears is like and I
hope you have more
luck than I did.

Vincent,

I haven't any direct news so far but your prompt will get me to ring
the person to whom this order is to be delivered.

I have not been able to investigate the general arrangement of the
decoupler ordered but, as a general observation, a spline fit is
generally a hand slide and the locking is then done by a nut. This
is the common fit of, for example, a drive shaft into a hub.

Hammer fits sound a bit suss.

Will post more information soon.

Seasons greetings to you.
