8N Ford Replacement Motor
Robert Kraft, Little Sioux, Iowa, replaced the aging motor in his 1950 Ford 8N tractor with a V4 Wisconsin air-cooled engine he removed from an old hay baler.
"The conversion was difficult because space is limited on the tractor and a flywheel and pressure plate had to be installed for a clutch," says Kraft. "I made a 3-in. adapter from parts of two International truck brake drums to fasten the Wisconsin engine to the Ford transmission, and the tractor's length was extended 8 in. to get far enough away from the blower. I added a starter and a gas tank from an old 50T International baler which mounts up front where the Ford radiator would have been positioned." The hood on Kraft's 8N tips forward exposing the gas tank, air cleaner, generator, carburetor and the rest of the key components, making the converted tractor easy to service. The muffler is designed to draw hot air off the motor, along with engine exhaust.
"It makes a nice, smooth running rig that has as much go as a conventional 8N Ford motor," notes Kraft.
