J1456_198412 MAXIMUM ALLOWABLE ROTATIONAL SPEED FOR INTERNAL COMBUSTION ENGINE FLYWHEELS

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