manifold heat riser rebuild kit & counterweight attachment

Posted by Dave Blandford On 2012/1/31 11:31:28

I am in the process of replacing manifold gaskets, and repainting the manifolds on my 1947 Clipper 6 cylinder.

I have a manifold heat riser rebuild kit, which includes a new spring, new bushings and a new shaft for the flapper valve inside the exhaust manifold. The flapper valve and the counterweight need to be re-used.

After 65 years of "attachment", the counter weight does not want to come off the shaft.

To complicate the process further, I have a buddy who is helping me on the project, and (with some 3 Stooges buffoonery) we have proceeded to crack the counterweight in half trying to punch the shaft from the cast iron weight.

And yesterday while I was at work, my buddy (a former machinist) was at my house doing a project for my wife, and he strayed-off to my garage, where he proceed to drill some slightly off-center holes through the counterweight trying to free the stuck shaft. I had warned him that I didn't have the tools to make this work, and it needed to be done my a machine shop, but, HEY, it's "2 Stooges" in action.

Three questions:

- Can the counterweight be welded ?

- Does the shaft need to be pressed-out, or drilled-out ?

- Anyone have a manifold riser counterweight for sale ?

Thanks, in advance, for the feedback.

Best regards,
