SAE Housing and Flywheel Sizes
The following graphic shows the typical configuration and their respective SAE denomination:
At Swift Equipment, we have listed the Society of Automotive Engineers (SAE) adaptation configurations. The below-mentioned configuration also enables you to a couple of the diesel and gas engines that also follows the same SAE standards. You must also check out the diagrammatic form for further understanding of respective SAE denomination also.
