Abstract
A two-stage cam shaft drive arrangement for an internal combustion engine employing a pair of flexible transmitters.

Flexible transmitter tensioners are engaged with the flexible transmitters on the side away from the cylinder block for ease of accessibility and to maintain a more compact engine configuration.
