The Stovebolt Site Forums The Shop Area Engine Shop 216 or 235?

I'm considering purchasing a take-out engine/4-speed trans assembly from a stovebolt truck, not sure of the year. The stamped number behind the dizzy begins with "DCM" followed by a 6-digit number which makes me think it might be a 1946 model 235, but that alpha code gets skipped in the code lists I can find. Anybody got any words of wisdom?

Jerry, according to the GM Heritage site, it's a 1946 Tonananda produced 216 from a 1 1/2 ton truck.

OK, thanks! I assume the trans would be a crash-box 4-speed? Those little details will influence what I'm willing to offer.

I'm thinking the crash box has the lock out 'trigger' for reverse?

From a 1984 article from the Light Commercial Vehicle Association magazine (which later became "This Old Truck" magazine and is now called "Vintage Truck" magazine:

"In 1948 Chevrolet was the first of the volume manufactures to offer a 4-speed synchro-mesh, helical gear transmission as regular equipment. It was an extra cost option. As a result of this complete redesign, the 4-speed transmission case was wider, higher, and longer. It was still of the same rigid, box-like cast iron construction as before. So that the new 4-speed transmission could be mounted interchangeably with the 3-speed transmission it was necessary to increase the length of the 3-speed transmission case and main shaft. Minor changes were made to the dash and tow panels in that a new seal was added to accommodate the steering column, gearshift, and the transmission cases. The new foot operated parking brake was moved to the extreme left side of the cab. A hand release rod was located just below the instrument panel. The foot operated parking brake offered a couple of advantages, it was easier to apply because more pressure can be applied with the leg and it helped to provide smooth starts on hill by allowing the driver to simultaneously accelerate the engine, engage the clutch, and release the parking brake lever. Only a slight amount of effort was needed to release the parking brake because of an 8 to 1 mechanical advantage. A new left-hand inner fender skirt was provided to allow space for the pedal mounting lever."

From the link that Tim provided,
DCM was for the 4000 series trucks.

The 4000 series had a 216.

The 4000 series trans 4 speed,
is listed as conventional with gears type as Spur.

Maybe someone can explain spur verses helical gears.
