Flywheels for Industrial Engines Used With Industrial Power Take-Offs Equipped With Driving-Ring Type Overcenter Clutches and Engine-Mounted Marine Gears and Single Bearing Engine-Mounted Power Generators
This SAE standard defines flywheel configuration for industry standardization, interchangeability, and compatibility. Table 1 and Figure 1 give the dimensions for he flywheels. For dimensions of industrial power take-offs with driving-ring type overcenter cluthes, see SAE J621. For flywheel dimensions for engine-mounted torque converters without front disconnect clutch, see SAE J927.
