This document has been declared "Stabilized" and will no longer be subjected to periodic reviews for currency. Users are responsible for verifying references and continued suitability or technical requirements. New technology may exist. 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. This document is intended to establish maximum allowable rotational speeds for flywheels under centrifugally imposed stresses.
