Final answer:
The RTV Bead should be placed on the flat surface above the step chamfer to ensure proper sealing and adhesion.
Step-by-step explanation:
When applying RTV Bead on a component with a step chamfer, the bead should be placed on the flat surface above the step chamfer. This ensures proper sealing and adhesion of the bead to the component. Placing the bead on the flat surface below the step chamfer may not provide optimal sealing, and placing the bead on the step chamfer itself may cause difficulties in achieving a uniform bead width and thickness.
Moreover, placing the bead only around fastener locations may not provide sufficient sealing for the entire component, especially if there are other areas that require sealing. Therefore, the recommended placement for the bead is on the flat surface above the step chamfer.
