...............................
Scope - This SAE Recommended Practice defines flywheel configuration to promote standardization of flywheels for engine mounted torque converters.
Suggested tolerances are to be measured on assembled engine. Table 1 and figure give
dimensions for flywheels for torque converters. For tourque converters with a front disconnect clutch, refer to applicable SAE Standard or Recommended Practice.
