Just put new wheel bearings in the front and rear wheels. It's been awhile since I took the wheels off the bike and can't remember how part #6 in the diagram interacts with the speedo gear #part 11. There are 3 threaded holes in part #6 and showing one bolt, but the fiche mentions 2 bolts?

I don't understand your question... ALL three are flatheads and are underneath the mounted speedo drive.....

I notice there's a screw on top of the gear but what makes the speedo gear move? On my nighthawk theres a notch in the gear that a lip from the wheel engages to turn the gear.

Apparently you have a broken part....I'll get a pic of the correct 'look' and post it.....

Part #6 in your original drawing should have a couple of tabs that project sideways.
They fit into notches in the speedo drive inner and make it turn.
The fiche shows the backside of the part, so you can't see the tabs.

Right Steve ?? Or do I have it backwards?

Bill, and gaillarry... I'm not at the shop, so a 450 wheel pic will have to wait.... BUT, here's one of the similarly configured 305 wheel drive.....


It takes the identical speedo drive unit, so you are either missing the notches (two) or the top 1/8 inch of the cylinder that forms the notches has been broken/ground off...........Sorry for the fuzzy pic.....
