SAE Housing & Flywheel DimensionsBelow are listed standard Society of Automotive Engineers (SAE) adaptation configurations. Thisconfiguration allows easy coupling to most diesel and gas engines which follow the same SAEstandards. The following graphic shows the typical configuration and their respective SAEdenomination:

To determine the SAE adaption in your specific application, simply matchdimensions XO, X8, XE, XF and XG to arrive at a combination of SAEadaptations for the engine housing and for the engine flywheel, i.e.: SAE#1Flywheel Housing with SAE#14 Flywheel.
