Sachs Tornado 3-speed hub repair advice needed.

Quoth dr. glen:

It works, yes, but it is late-engaging.
I assume it's a coaster brake but - according to this site:
http://www.ddol-las.fsnet.co.uk/hubgear.htm - it could vary. It
seems like that over the years the gear had three types: coaster-,
drum- and later years, disc brakes. I don't believe it have a disc
break though.

It is easy to tell. If you apply the brake by turning the pedals
backward, it's a coaster brake.

If you squeeze a handle on the handlebars to apply the brake, it's a
drum brake.

The label on the hub says: "Sachs Torpedo Dreigang",

"Dreigang" is German for "three speed."

and just to the
right of this is symbol and and the number: 36. It look something like
this:

36

Does anybody know what it means?

Yes, that's how many spoke holes there are in the hub.

Hmm, I've tried it and I must say that your statement is probably
correct. I have only done it for a few times but it do feel snappier -
although the brake is still very late-engaging of course

That suggests a coaster brake. Make sure that the arm under the left
chainstay is securely bolted in place so it can't move around.

Lubrication might help, medium-weight oil is good. If the hub doesn't
have an oil port, you can lay the bike on its left side, unscrew the
little chain that connects the shift cable to the hub, and drip oil in
there. If it has been a while, I'd put in 30 drops.

After I cleaned the parts I understood that there were something fishy
with the expanding part, it almost didn't expand at all no matter how
much pressure I put in to my efforts. I assumed that this should be
the reason for the late-engaging and I went and bought a new one. The
new one expands real easy so tomorrow I will try and put it all
together.

They are usually too stiff to expand by hand. The mechanical advantage
available, plus the fact that you are doing this with your leg
muscles, is generally more than enough to overcome this. It needs to
be stiff to make sure that it will return when you want it to.

Where did you find replacement parts for a Torpedo hub?
