Front axle alignment
« on: December 09, 2007, 03:55:45 PM »
Wheels are finally done, and time to put 'em on the bike so that I can roll it around the garage and make motorcycle noises  ;D

According to the parts diagrams/manuals I'm not missing anything on the front axle - but should it fit tightly on the hub?  My concern is getting the wheel centered in the forks.  Thanks :)

Sweet looking wheels! 

From what I remember, the mounting is pretty straight forward assuming you have all the spacers and whatnot.  If you have the brakes on the forks, they pretty much dictate where the wheel is going to sit,  I seem to remember that the axles has flanges on one side that trap the fork mount.

Good Luck!

One side of the axle has a flange thats captured by the forks, and it looks like the speedo drive sits flush against the other fork.

The axle has to tighten down and be torqued to spec on the wheel assembly, the easiest way to clamp the "head" end for torquing is to clamp it into the fork. It looks like you have some free axle, and you could slide the axle back and forth in the wheel as it is in the picture. If that's the case, something is disastrously wrong. I don't know what bike you have, but it looks like you have no spacer on the non-speedo side. There has to be a spacer that fits into the oil seal on the bearing retainer, if it's there it should stick out more than it does I think. If it is in there, the only way it could push in too far is if the inner spacer collar is missing  or too short.

Its a '71 CB750K - according to the parts diagram, its all there... hence the confusion.  If I put it in the forks and clamp it down the wheel is sandwiched in there by the speedo drive so it *looks* ok.

edit - I've got 3 front axles here, and they're all the same length as well, I did consider that.

In your pic it looks like you got play, should be none.

In the manual pic you have shown, number 3 may be  missing and is what they are talking about.

Also speedo should not be tight to fork...by design..the nut is tightened up on the axle with everything in place. The opposite end actually floats.. that is to say the nut end with the lip determines position and the other end gets clamped where it ends up,  usually leaving room between speedo drive and fork.

Nut (and #3 spacer) are on the non-speedo side, in the first pic.

They are on the correct side of the wheel but the NUT is on the wrong way round so it wont do up

Holds up great - it sticks best to other paint, with a light scuffing w/ medium grit sandpaper.  Its not resistant to brake fluid though but heat is no problem.  It really needs some heat to cure, although leaving your parts in the garage for a few weeks during the summer takes care of that pretty well.  Not as tough as powdercoat, but it wont flake off.

Looks great on track bikes...
