I considered posting this question in the Technical Discussion - if that is the more appropriate venue, I'll be glad to move it there, or, the administrators may decide to do so.

I'm wondering when the automobile lines quit using the old torque tube and changed over to open drive lines - I've heard it called Hotchkiss Drive, not sure if that is technically correct. I'm gonna make a guess that the change occurred with the 1947 "Postwar" models. But, if it occurred earlier, I'd like to know when that change took place.

And, on the same subject, when did the light trucks make this change? Again, my guess would be the 1949 model year, as that was the first new Postwar truck

Thanks in advance for your responses.

I don't know if Studebaker ever used a closed driveline, unless perhaps on the EMF-derived models with the rear-mounted transaxle. They were definitely using open drive lines in the pre-War era, both cars and trucks.

I was thinking the same thing as Gord. My 1937 Dictator has open drive.

closed drive line was a big thing for chevrolet but it may be much more rare in a studebaker.

Yes, so did my first Car, a 1950 Chev. the whole Car was a Real "Piece of Work"! As in cheaply designed JUNK! :(


It had a "Ball Bearing" Transmission and a "Dip and Splash" no Oil pump 216 Engine, used all the way to 1953 without another "piece of work"; the Powerglide. :mad:

Makes me recall putting a Chevrolet six from a PowerGlide car into a 1953 standard shift car to get the "better' (oiling) engine.

How can it be "closed" (enclosed) and also "2 piece"? Volvo used a differential/rear axle similar to Studebaker at that time. I owned a PV444. I remember it as having an open drive shaft (Is my memory incorrect on this - its only been five decades)?

I do not recall any Studebaker branded vehicles having a torque tube drive. Perhaps someone that knows the prewar models better than I do can come up with an obscure one.

Rich, those 'early' Chevy's didn't have pressure lubrication to the lower end of the connecting rods, but they certainly had an oil pump!

Ford cars finally went to open drive in 1949.
But the pickup trucks had an open drive in 1947, maybe '46?

Chev was closed thru '54 inc. 1/2 T trucks, Buick thru '60 inc. 2pc in '58 Limited at least, Olds in early 50's, Ford & Merc thru 48, Rambler in 50's. The rest were open as far as I can remember. Early Chev had an oil pump to lube rocker shaft, 15 psi. max. -Jim

OK, not completely closed. My Volvo has a closed tunnel for the front driveline to a carrier bearing that has about 8 inches working opening to access the bearing and then closed again to the rear end.

Also, Pontiac Tempest had what they called a torquetube thru '63 with their "spagetti" driveshaft.- Jim

My 1965 Rambler Classic had a torque tube. Had to unbolt the rear end and move it when I rebuilt the trans.

To me, that is still an open, not closed or torque tube, driveshaft. It just happens to be partially enclosed.

I do not know. Looks pretty closed to me.

It looks ENclosed, but not a closed torque tube.
