I have a problem with a welded bolt rubbing against the sprocket. The bolt that holds the fork of the brake assembly. Its like its just too long. I was about to shorten it but before I did I wanted to see if anyone else has had this issue. Is there an easier solution that cutting the bolt?

I'm having the same problem but not as bad. Is this the newer azusa? I also have an older one that doesn't have this issues, the bolt is way shorter.

Also, do you have the right bushing in the drum sprocket? It came with 3 bushings for the rear, 3 different sizes. Just a thought.

That's the first thing I checked. I thought I screwed the order up. I did it the way the guide does it and another way, but that welded bolt still scrapes the sprocket. So much that you have to really force the rear wheel to move. I just found on another thread a guy mentioning an issue with the welded bolt being too long, I guess its a real problem and not something I'm doing wrong

Is it running the entire circumference of the sprocket? If so, install a flat washer in between the spacer and the axle tab on the sprocket side. If you can't get the assembly back together, you may need to grind the washer thickness off the opposite side spacer. That will shift the wheel to the right about 3/32".

I kind of have a little get together a couple times a year.
Last one in October had a bunch of folks for the day.
75 or more.
Look for upcoming in the Spring.

Why not just cut a bit off the bolt?

Well, I should have worded this better. I got on a tangent. I guess my point was if it isn't rubbing continuously, it's not the bolt but rather an untrue sprocket. These kits are notorious for that. So trimming the bolt really wouldn't help as much as getting the sprocket true'd up. I agree grinding 1/16-1/8" off the bolt would be way easier if needed. I was reinventing the wheel there...[emoji51]

Twid,
minibikin' is right on about these Azusa wheels and sprockets wobbling. My son and I have had first hand experience with this! Have you checked to see if you have a wobbler? If so, that is the FIRST thing you need to correct.

Sure looks like that brake assembly is sitting too far in the drum/sprocket , the fork that keeps it from turning is close to rubbing the sprocket.My bet is the wrong or a missing bushing between the drum and backing plate.
