Sickle blade struck an object and bent the 1/2" X 1" gear shaft

Screwdriver, Power Drill, Nutdriver
Completely dismantled trimmer to replace gear box then reassembled using all the parts ordered. I had to be careful reassembling the blades as the two gears had to be installed 180 degrees so blades would oscillate as designed otherwise the gear shaft could be bent again when starting engine.
