Re: Correct Crankshaft for 1956 RDE-18

[ADAM GIBB]

OLCAH,
The dimensions that I am most interested in would be on the top end. The distance from the bottom of the cam drive pin hole, to the top of the taper above the bearing surface. It is the carbon seal retaining setup that is not allowing me to seat the flywheel. I am away until Friday, but could post a picture when I get back.

I may be beating a dead horse here, but this has me stumped.

I came to the same conclusion as Frank with regard to all of the possible setups. The only think that was never done from the factory, was supplying the carbon seal on the top end of a 203655. Add the fact that they went back to the 302530 in later years, tells me that the difference must be in the top end. And following Franks logic, yes the 203655 would work anywhere the 302530 does, but not the other way around.
