Porsche Junior engine cutaway

This is a cutaway of the Porsche Junior 822 cc single cylinder air cooled diesel engine, the smallest of their line of tractors built from 1956 till 1963. For simplicity they all used the same internal parts. The hand crank starter made have been an issue in cold weather! Over 125,000 of these tractors were built and they're enjoying popularity today due to the general popularity of Porsche cars.

Thanks, Rolf.
