Default Re: whistling motor

One of my PK80's devoloped a "whistle" after about 100 miles, more of a gear "Howl", looked it over, the keyway on the small pinion gear seemed to be jammed up, removed the loc screw, used a bit of loc-tight{blue), put a new keyway on, has not been back since. Hope that helps.
