Shelburne Falls, MA, same as they are now, as you well know if you have
a Corvair. I'm not really missing the '65 turbo convertible body with
the 4-carb 140 motor swapped in I had for a few years. It was
interesting, but needed a great deal I didn't have time or money to give
it to be good. Especially in the salt-fest that is the northeastern US
in winter.

WRONG. Because that's where Larry and Marty and Doc were ordering
them from in bulk for their shops. I wasn't picky, whoever I was
closest to at the moment I picked up a spare for in the trunk - that
inevitably ended up pressed into service much sooner than expected.

And I suspect that Clarks, Cotrofeld and Corvair Underground were
all sourcing the same supplier, too. Because they ALL died till they
cycled through the old stock.

I had to replace the input flange on a German 10,000 rpm 500 hp AC
dynamometer. The flange mounted on the slightly tapered stator shaft,
about 65 mm in diameter. Same deal, pump up to 2000 bar and pull off
with a slight push. Replacing was the reverse, a small bolt in the
end of the shaft with a washer to bear on the flange, and crank up the
pressure. The flange just glides into place. Very neat, but one
small scratch in the near mirror finished shaft surface and I'd guess
your screwed. A lot nicer than some other dynos I've worked on with
shrink fit straight shafts with keys.

How do these couplings work? I've having problems visualizing.

Thanks,

Wes


I'm still curious. Can anyone explain how the coupling works?

I came across this while looking for a different type of hydraulic
coupling...

There are detailed mounting/demounting instructions in the downloads
at the bottom of the page.
