3 Broken Driveplates / Flexplates 1964 Cadillac DeVille Convertible

Hi All from the UK,


My family have had this car from new, bought in London!


This was a very reliable car driven all over Europe and even China. But then it was interfered with and I have been dealing problems ever since. Most of the drive train was rebuilt including engine and gearbox.


But given lots of time and money it has been running quite well and has done 3000 miles since the rebuild...

BUT it has just broken it 3rd Drive Plate!! Hairline crack in the central section.

Does anyone have any ideas why this might be?

Thanks in Advance Hugh

I'm thinking starter motor brace too.

If it is missing and Jason and Russ don't have one, you can make one yourself. None were available when I required one, so made this up and it seems fine. Not a perfect solution and not as robust as the original, but it only has to arrest flexing to be successful.

thanks

there is 1 broken bolt hole with no bolt on the starter motor housing....but i think this might be  historic ie. prior to to drive train rebuild

also i remember on the day it broke, when cranked when cold it did make a strange crunching noise....it probablu went 60 miles later...

also at least 2 of the 3 (maybe all 3) breakages happened when i poked the accelorator (when fully in motion and engine fully warmed up)

see pic of broken bolthole taken a while ago....

You can put a metal washer -on the bolt that goes to the starters broken bolt hole to aid in stabilizing the starter when mounted

Enjoy

Hello I've been restoring a 63 for way to many years. Down to almost done, but have issue with trans linkage, when column in park shift rod 2 inches short. everything original. been trying to find picture of manual rod hooked up from under car to see position of linkage. was wondering if anybody has access for pictures. I wanted to see if my manual linkage is bent  wrong out of the trans if somebody dropped the trans or something. Doesn't make sense why it doesn't work. Thanks for any input…

Torque converter grab when idling in Drive

Posted by Cliff Johnston on June 14, 2021 at 8:47pm 2 Comments

Hi Everyone, been quite a while since i have been on here.

I have had an issue with the idle on my 64 Coupe Deville ever since i have had it.

With the Idle set high enough that it is smooth, but still a nice idle, the RPM seems only slightly too high for the stall of the Torque Converter. And therefore it tends to sit there and grab and lunge a bit. So until now, i have been putting the car in Neutral at the lights to stop this happening.

I've had the car dyno tuned and…
