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. -- Bruce -- |

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? Wes -- "Additionally as a security officer, I carry a gun to protect government officials but my life isn't worth protecting at home in their eyes."

I came across this while looking for a different type of hydraulic coupling... http://www.skf.com/portal/skf/home/p...newlink=12_1_6 There are detailed mounting/demounting instructions in the downloads at the bottom of the page. -- Ned Simmons |
