This SAE Recommended Practice applies to flywheels and flywheel-starter ring gear assemblies used with internal combustion engines of the spark ignition and diesel type equipped with a governor or speed limiting device. Engine sizes are those capable of using SAE No. 6 through SAE No. 00 flywheel housings.

This document applies to methods used to determine the rotational speed capability of flywheels for stresses imposed by centrifugal forces only.

Purpose-This document is intended to establish maximum allowable rotational speeds for flywheels under centrifugally imposed stresses
