Re: 1930 Elto Senior Speedster Mag plate retrofit woes

[Buccaneer]

quote PM T2:

If the sleeve over the crankcase neck is steel, its probably just a spacer they made up to take up slack between the original neck and the Johnson mag plate they grafted onto it. Remove the spacer and see if your Evinrude mag plate fits on. A simple measurement sequence would tell you that ahead of doing any actual removal work. I bet that you’ll end up cutting that sleeve off and the mag plate will suddenly fit with minimal fuss.

The only way you’ll drive the original crankcase neck (you call it a post) out of the housing is if you break it off and destroy the entire housing. Its cast as one piece, and the bearing is a press-fit insert.

Knuckle-buster flywheel diameter is 9.500″.

PM T2, I see why you get paid the "Big Bucks"! It didn’t cross my mind that my Speedster
already had a sleeve on the "post / neck" to make it a larger OD, and hence, fit the
mag plate from Rube Goldberg affair.
I should have asked the audience the Timer ID, or the Neck OD on an original Speedster of 1930.
Didn’t think of it, but probably no one else has one apart to measure anyway.

In looking at my photos again, on the top side of the neck, there’s a lip, that appears to
be less than 1/8" wide. I need the neck to be 3/16" thinner total diameter, and if that is a sleeve,
that might just "do it" as you say.

Not sure if my bearing puller is thin enough to bite into that seam in the bottom
of the sleeve. If not, any good ideas on how to pull it off?

Sounds like I’m good to go as far as the flywheel OD……. great!
Thanks again!
