Hello Ed,
This is the typical european way of attaching drums back in the good old
days.
It's obviouse that the screws doesn't have any major clamping force, my
guess is that it's just a simple way of keeping the drums in position when
the wheels are off.
Anybody else with a better idea?
Bo the swede

That's exactly what I was going to say.

I just checked the 5 brake drums that I have, and found the following internal
diameters (of the braking surface):

9.045"
9.051"
9.052"
9.056"
9.058"

Does anyone know what the maximum allowable ID is for the Amphi brake drums.
Also, as a point of interest, what was the ID of a NEW Amphi drum?

BTW, I noticed that the drums carry a prominent number: C.06.1.04.0.11
Does anyone know the significance of this number?

Finally, The drums also seem to carry a logo. The logo is a circle, with a large
"W" inside the lower half. There is some character above the "W", but I can't
make it out. Could the unknown character be a "V", and I'm looking at a
Volkswagen logo?

Did VW supply the Amphi brake drums? If so, the drums were likely an existing VW
item, and should be crossable to some VW car model, opening up a strong
possibility of sourcing drums for Amphi.

Ed, the American manual says original size is 9.055 but OK down to 9.145 however
the original German manuals have more information and are generally more
accurate, they quote 230mm and OK down to 232.3

The part number is Mercedes and the logo is the component supplier, they are
common to some other rare Merc. The logo is the parts supplier - same with the
wheels and yes that is a date code - no idea why though. Merc went to wider
wheels and disk brakes by mid 60s so not much is common.

I had my brake drums turned, but I hit some legal difficulties here in
California.

Although I had the service manual specs that the drum ID was 9.055" new and
could be machined to a maximum ID of 9.145", I could not get any normal auto
shop (like Midas) to turn the drums. All cited a concern for liability, since
they could not independently verify the maximum ID themselves. If it wasn't
stamped on the drum, or if they couldn't find an Amphicar 770 in their computer
files (yeah, that's likely), they refused the job.

I finally had to use an auto machine shop, who wrote the order up as "machine 5
loose drums". (Straight labor rate, cost was $122.) I don't know what the legal
magic is that let's an "auto machine shop" do the work, but maybe it's just a
California phenomena. FWIW.

If you just had your brake shoes relined, & now have trouble getting your drums on, here's what happened to me 25 years ago.

The new brake lining was a little thicker that the original, so that was just enough to make it too big for the drum to fit. The solution was to have the 're-liner guy' arc-the shoes......which means grinding off a little material to make them thinner.



About the new Amphi-lovers site.

I'm of the opinion that whoever's running it has put a lot of time & effort into it, & is in the best position to find a better way.

So, keep up the good work & continue doing this for us.

One suggestion: before closing down the old list, how about a mass email-ing to everyone explaining exactly how the new list would work,


Till later...& Happy New Year!!!
