Needed shouldered bolt for drum brake anti-rotation arm

flynn

I need another shouldered bolt that attaches the anti-rotation arm to the drum brake housing. The threads of the current bolt I have are toast. Please let me know if you have one available.

See item 38 in attached picture.

I needed a sholder bolt for calipar arm just a couple days ago. I used a regular fully threaded bolt I got from the hardware store. Worked fine.

I think that part is still available new for about $4.

Cool, thanks for the heads up 5twins. I just havn't had an opportunity to make it to a bike shop (I'm kinda remote to most Yamaha shops).

Well it turns out that it is a discontinued part as well as it's predecessor.

I ended up cuting off the threaded end, drilling and tapping the shoulder section and running a stainless steel cap screw into the old portion. With thread lock, and a split washer it'll work well and should stay in.

I think I found the shoulder bolt you are refering to at Lowes in the hardware nuts and bolts section. I'll pick one up next time I'm there just to compare it to the original on my bike.........BG

That's a rather special bolt. The shoulder diameter is larger than the threaded part and the "head" is not hex but round with 2 flats. Would this place be anywhere near you?
