LYCOMING OPERATOR'S MANUAL
IO-320 SERIES
The letter "L" in the model prefix denotes the reverse rotation of the basic model. Example:
model IO-320-C has clockwise rotation of the crankshaft. Therefore, LIO-320-C has
counterclockwise rotation of the crankshaft. Likewise, the rotation of the accessory drives of
the LIO-320-C are opposite those of the basic model as listed in Section 2 of this manual
Operational aspects of both engines are the same and performance curves and specifications
for the basic model will apply to the model with reverse rotation.
