What is the first step in removing the valve cover breather assembly?

The correct first step in removing the valve cover breather assembly is to remove the 10-millimeter screw and washer retaining the assembly. This step is crucial because it secures the breather assembly to the engine, and removing it allows you to access the assembly itself for further disassembly.

Once the screw and washer are removed, the breather assembly can typically be lifted off more easily. This method of disassembly ensures that you are working in a systematic manner, preventing potential damage to the assembly or the surrounding parts. Furthermore, securing and loosening components in the correct sequence is vital in small engine repair to maintain organization and efficiency during maintenance.

While loosening the breathing cap, disconnecting the hoses, or removing the valve cover might seem like logical steps, they would not be the appropriate initial approach, as they are contingent steps that can only be performed after the screw and washer are removed. Therefore, starting with the screw and washer sets the foundation for safely and effectively accessing the breather assembly.
