SAE J620_201210

This SAE Standard defines flywheel configurations for industry standardization, interchangeability, and compatibility.

Table 1 and Figure 1 give the dimensions for the flywheels.

For dimensions of industrial power take-offs with driving-ring type overcenter clutches, see SAE J621.

For flywheel dimensions for engine-mounted torque converters without front disconnect clutch, see SAE J927.
