new clutch bevel wheel won't fit on

[BikeGuyver]

i got the new bevel wheel but it doesn't seem to want to fit on. i lubed up the shaft, and pounded the heck out of it with a wood block, but it's still sticking out about a 1/2 inch. i only saw one size on the bikeberry site. any suggestions? i figure if it's on so tight i don't even need the woodruff key, cuz it fell out as i was pounding the wheel in and i just left it out.

Pounding isn't right ,some one possibly Norm will know what's going on ,even if you got it on that way it would loosen up quickly ,from viabration it needs the key
