Default 1959 Kenworth Chain Drive

I had no idea that the chain drive concept for heavy hauling motive power was still a valid concept in 1959. Big off road logging truck.

Wow, neat! Is that an NH Cummins? Mine looks similar, somewhat different intake manifold?

My 1955 Crown originally had a "Silent Drive" to the second axle, but the sheaves and belts are long gone.

Keith, I have heard the term "Gates Rubber Band Drive" to describe the belt driven pusher axle. A friend of mine collects chain drive Sterlings. They are really neat trucks. I love everything about chain drive, and hope to one day have a chain driven truck. An M26 Dragon Wagon with a 440 Hall-Scott would be nice, but I could settle for an AC Mack

I remember those rubber band drives as a kid. My family is from Iowa and an uncle cursed the things. He said they didn't do anything but slip and when the belt broke it could lock up a wheel.

Looks like a worm-drive differential?

The differential doesn't have the signature bearing cover of the worm drive set up on the back side so more than likely this is a double-reduction unit. There is yet another reduction gained on the chain sprockets so this thing is geared in the basement. Probably never saw speeds much above 30 mph.

The water tank referenced to which is mounted behind the cab holds 300+ gallons of water and was used for brake cooling.

Advantages of this chain drive set up would be added clearance and positive driving action of the tires on a given side. Differential action would still be needed for corners.
