Lawn mower blade hub.
I'm trying to figure out how to get the blade hub off of the bottom end of the crankshaft on my TroyBilt - Honda powered mower. There is no set screw that I can find, and it doesn't appear to be a thread off. There is a key, but I can find nothing that suggests how to get this thing off.
I need to take it off so I can change the bottom crankshaft oil seal. This is a Honda GCV160 engine.
Thanks for any input.
