Paul, Is there a documented solution to replace the flexplate with a
more substantial unit to avoid disintegration or cracking?

Thanks Joe Berki


Well some of people have used a steel flywheel. Dave Leonard as I
recall.

The best solution is use the stock plate with a rubber coupling.


Paul Lamar


Paul did you get a chance to publish the final CAD drawings and files
for the coupling?  I might have missed it if so.

Thanks.

Scott Gettings


We have three designs. Which one do you like.?


Paul

Which ever one would be the most practical to build in a local
machine shop based on the CAD drawings, and also fit into Tracys
redrive without other modifications.


Thanks

Scott Gettings

This is the simple-est and easiest to build. The blue is just a chunk
of aluminum bar.

The stock FORD part is cut down a bit on the lathe.


Paul Lamar



Excellent, thank you.  These look great.  I already have the Ford
part.

A few remaining questions: So in this version, the flex
plate/isolators and the housing/Ford part are not actually bolted
together, but are simply captured and “float” between the redrive and
engine, correct? If so, do we need to assure some minimal amount of
free play between the components?

Can the aluminum housing be 2024 or does it need a higher
specification?

Are the isolators a standard silicone product or rubber bushing
stock?   Same as the isolation bolt metal bushings.

BTW, do these drawings have dimensions (or files)  that can be used
by my local machine shop to build the parts?

Thanks again, Paul.

Regards,

Scott Gettings

Yes.

2024 is OK.

Probably machined out of red silicon rubber block from Master Carr.

You could wrap up red silicon tape on silicon hose probably.

Paul Lamar


Might one of these work for the isolators?

No I would make them out of 4130 bar and have them heat treated.
The OD would be roughly the same as the metric socket head bolts,
Could be a little larger.
