You don't need the "Get-ChildItem" since you're only addressing a single file, you need to use $_.Split(':')[2], and if you want to to overwrite the source file, you need to put Get-Content in parenthesis, so that PS will read the whole file before continuing with the pipeline.
(Get-Content F:\Powershell\string_output2.txt) | % {$_.Split(':')[2]} | Out-File F:\Powershell\string_output22.txt

That's a Unicode; use Out-File's -Encoding argument:
(Get-Content F:\Powershell\string_output2.txt) | % {$_.Split(':')[2]} | Out-File F:\Powershell\string_output22.txt -Encoding ASCII

Get-Content F:\Powershell\string_output2.txt

Open in new window

print the expected strings?
Since you're replacing the original file, have you restored string_output2.txt to one that was created by the original source?
You can try Set-Content instead of Out-File as well.
