View Full Version : Do sportster use different front axles for mag wheels and spoked wheels?

Or perhaps different spacers? I put on a 21" spoke wheel and it looks like the front axle is bottoming out on the spacer and not going in all the way. The nut on the axle on the brake side fork only goes on about half way looks unsafe to me.

you can see the axle has a lip that goes past the lower fork tube, I dont think the wheel had a spacer on that side with a larger ID if it did I dont have it anymore. Just wondering what people think before I turn down the axle on the lathe. I just dont know why its not going back together the same it came apart.

Turn down the spacer(s) before you turn down the axle!
What style hub? Going from tapered to sealed bearings?
Note: watch out for caliper to spoke clearance

open 7/8" bearings same that was on the mag for a 92xl, wheel already works fine in the front end. rode it around as is, just dont like the axle bolt issue. I was thinking of turning down the spacer first. Was hoping to find out what the deal was before machining anything incase I missed some detail somewhere. Just seems weird to me.

Does this look right. I used a short spacer in the bearing and the lip on the axle pressed against that. I had to pull the fork leg out about 1/8" before tightening the alen clamp bolt[tough to do with one person] but the wheel seems to be pretty centered. It seems to line up where the wear marks on the axle are. I had the bike apart for along time and couldn't remember how it was supposed to be.

Sounds like your figuring it out.
The tapered style bearing seals need a spacer to seal against,so I bet you just mis-placed the right-hand one.
The new hub might have a longer bearing/inner spacer stack than the mag did. There are two diff width narrow glide spoke hubs from the factory (disc style anyway)
Did you 86 a speedo drive? That would explain a missing spacerIs the tire centered in the forks?
How is the caliper to rotor relationship? Or did you ditch the front brake?

I kept the speedo drive in there just to keep things simple. Caliper clears spokes but is close. Caliper fits rotor fine. Tire is centered as long as I pull the non brake lower leg out that 1/8" and tighten the clamp bolt. I am gonna ride it a little today and see if it stays put.

I just swapped out the front and thought I had measured everything right. I might have assembled something wrong, but I'm about 1/4" uneven to one side. I need to fix it, but have to ride in the mean time. am I gonna die? lol

You'll be fine with a quarter inch offset. Caliper or fender interference?

no brake, no fender :)
