Technical what year did cadillac go to open driveline

guys what year did cadillac go to open driveline? was 1947 a torque tube? thanks

 

I know for sure that they were still using hotchkiss drive on the 1953 series 62 cars still. I'm not sure how much longer after that they still used the system, but the 1947 would have used it as well

thanks! i found a picture of a 1955 cadillac rear end and it's open. just found a picture of a 1953 cadillac rear end and it's open.

 

Around late 1939 Hydramatics were released by GM in 1940 Oldsmobiles. I believe that they were fitted with an open drive train (Propeller shaft) earlier than this. The hydramatic was not offered by Cadillac until 1941. I've never seen a hydramatic with a closed drive train coupling, (Don't know about tanks though) they have all been open like my 1946 Oldsmobile. 1947 was an open drive train and not a torque tube. I've seen a 48 with leaf springs and an OEM panhard bar.

Appears 1933 was the last year of shaft drive (Torque tube) as below is a 34 Cadillac showing an open drive train


Here's a Cadillac book and 1947 specifications from GM again.


Here is photo to answer your question.

 

My '41Cad ragtop had an open drive line
as far as I can remember, but it's been
almost 60 years ago.

very interesting!!

 

I was unaware Cadillac ever had a closed driveline.
Every one I've ever seen had an open driveline.
Including the diagram above

 

You have to get back to the antique era to find a Cadillac with a torque tube.
Stump, the '53 - '54 GMC & '54 Chev Hydramatic pickups are closed driveshaft ...

 

Don't think Cadillac used a torque tube between 1940 and 2000. Some '30's had them and some post 2000 have them.

 

Hi ...Open tail shaft after 1939.....

 

reason i asked was F1 truck i called about was supposed to fitted with a 47 cadillac rear end and sounds like it may well be. thanks.

 

Didn't know that, I've never seen one with a torque ball and tube. I see the columns come up from time to time. Thanks for clarifying that.

 

Torque tube setups did not work well with step shift auto transmissions as it carried distinct thumps at shift points. The early GMC and Chevy trucks had a "half torque tube" and a half open drive shaft. I believe the torque tube was not really a torque tube, but a way of keeping dirt out of the back of the transmission.
