Hi Rohmell....I went to Harbor freight and bought the 80 pc Woodruff Key assortment.
came home all excited figuring ahhh finally going to fix this thing....and Viola......
Not One single key would fit the damn thing. I had the size as far as length and possilbly height, but every singe one of them was too wide and would not fit into the slot. Also I went to Home depot for the nut....no go...even the largest bolt [metric 16.]
was wrong size...seems like every thing here is totally unorthodox sizes. Almost like the
chinese determined to make sure that there are no standard fixes...in hopes that you just go and buy another engine from them. Cant replace the nut [even went to 2 auto supply stores] no standard washer will fit over the shaft...This is REALLY ridiculous.
I have worked on Cars and Motorcycles for years...and never have I had this type of problems. BTW...we used to call woodruff keys, rocker keys because of the shape.
