So this 105 was running, but in need of a growing list of small repairs at the time it was parked. One of them was that the PTO button had fallen out and been lost during mowing, due to the PTO lever being bent and going past its stop. I purchased a threaded bronze version, as I'm planning on getting a few attachments that will necessitate belt changes, and this will help keep me from losing this one too.
For the threaded versions of the PTO button, does anyone know if the locknut is supposed to be tightened such that it is kept firmly in place, or is it supposed to be kept slightly loose, so that the button can rotate in the arm/bracket?
