This SAE standard defines flywheel configuration for industry standardization, interchangeability, and compatibility. Table 1 and the figure give the dimensions for the flywheels. For dimensions of industrial power take-offs with driving-ring type over-center clutches, see SAE J621. For flywheel dimensions for engine mounted torque converters without front disconnect clutch, see SAE J927.

This recommended practice incorporates recommended dimensions for flywheels for use with single bearing power generators in the range of 10-500kW, operating at speeds of 1000-1800 rpm. Driving torque, fastener strength, and rotative speeds shall be consistent with good design practice.

This SAE Recommended Practice applies to flywheels for dry spring-loaded clutches used on internal combustion engines. Figure 1 and Tables 1, 2, and 3 report information currently used in the industry. Clutches requiring other dimensions are also manufactured. Dimensions given are primarily for single-plate clutches. Flywheels for two plate clutches have the same dimensions if an adaptor for the intermediate plate and second driven disc is supplied with the clutch. If instead the flywheel is to be extended to adapt the intermediate plate and second driven member, consult the clutch manufacturer for the required J dimension and drive arrangements for the intermediate plate. See SAE J1806 for flywheels for size 14 and 15.5 two plate pull-type clutches.

This SAE Recommended Practice defines flywheel configuration to promote standardization of flywheels for dry spring-loaded clutches. Clutches to fit flywheels with configurations per this document may not be commercially available. Availability should be ascertained prior to flywheel design Figure 1 and Table 1A.

It is anticipated that this SAE Recommended Practice will be only one step in a comprehensive evaluation of the vehicle/transmission application. This document alone is not adequate “due care” to insure against high-speed seizure or other high-speed problems. The notes printed in bold print throughout the practice convey important information about the test itself or the results and should be considered carefully. All references to transmissions also apply to transaxles, except for the unbalance evaluation which applies only to rear-wheel-drive transmissions with propeller shaft output.

This recommended practice applies to driving ring type overcenter clutches such as are used in industrial power takeoffs.
