Anybody spare a sensor?

[Slonishku]

I just scored a rear wheel for my FJR that I'll be riding in the Iron Butt Rally. I'm sending this wheel ahead to the Jacksonville, FL checkpoint. The problem is, the guy I bought it from sent it to me minus the rear wheel ABS sensor magnet. Does anyone know where I can find one on extremely short notice? Failing that, anyone have one they'd be willing to lend out for the duration of the rally? Last minute rally crap is a son of a bitch!

Are you talking about the sensor that mounts with a single button head screw into the hub on the right side of the swing arm? The one with the electrical wire that runs along the brake strut and disappears under the right side cover near the rear brake reservoir? Is something wrong with the one on your bike?

I still have the one from my wrecked '06. Will it work for you?

Let me know.

No, I meant the disc fixed to the wheel by 3 bolts that says "Do not let a magnet touch this part" (or something to that effect) on it. It has no independent part number and doesn't appear on the parts fiche because it's part of the wheel.

Sorry my friend, my rear wheel is long gone.

Good luck in securing the part.

Brodie, you're wheel wouldn't have worked. They changed the ABS system starting in 08 hence why 04-07 abs wheels are incompatible with 08+ wheels.

Alex, if there is no part number for that ring, I think you are screwed. Why the hell did they take it off? How does it even come off?

This what you need ?

Highlander to the rescue!

Hey what can I say except I like spending other peoples money !

Very interesting find, because that's the very same one off my wheel. I just spoke to the guys, they yanked the eBay add and are sending it to me. The problem is, the bolts are gone. Does anyone know anything about these bolts? That's all I need at this point.

They look like Torx head machine screws if you're talking about the 3 black ones in the photo. I bet they are a std thread, I'd go find a bolt that just works at the local hardware store. I'm sure they'll have it in an allen head.

From the looks of the image that Scooter provided the bolts look like a button head screw with a torx bit socket. The thread should be easily measured by your wheel. My "wild ass" guess would be a 6MM thread. If you use philips head button head screws make sure they will have thin enough heads to clear the sensor or what ever else lives in that area. Remember, this is a spinning item, that clearance must be with the wheel rotating,

DUH.

When you get the screws that work, I would suggest a drop of blue loctite on the threads - just for security sake. I would hate to have a DNF on day 10 because of this silly item.

Good luck, be safe, and have a great run in a few weeks!

It turns out that they're M5 0.8 x16mm. I picked up a variety of them- hex, Phillips, socket- and will see what works best when the sensor showsmup on Sunday.

How did you find out the specs? Yammie really screwed up not putting that part in the parts diagrams.

As for Yammie screwing this one up- yeppers. The only reference of any sort I could find was in the service manual on page 4-26. It shows the rotor and three bolts. It shows the torque specs, and mentions them on the "reaer wheel reassembly" as something to be replaced every time. I tried numerous dealers, etc. and NO ONE could find anything as far as a part number, etc. In theory, there has to be one, as they are to be replaced whnever the rotor is removed. Meh. **** 'em.

I bought a generic box of a variety of "Sportbike Fasteners' at the local Yammaha Stealership. I tried a few until I found something that fit. A 15mm M5x 0.8 would go something less than 1/2 a millimeter through the threaded hole out the back. So I got some 16mm zinc plated bolts from the local OSH, figuring I'd make full use of the avaiable thread space with the soon-to-arrive rotor in place. From the hi-res version of the photo you posted, I eyeballed a scale for the bolt heads relative to the rotor bolts. So I should be good to go, but we'll see on Tuesday.

I picked up my new wheel today from the dealer and I saw it as soon as it set it on the counter:

I thought oh ****! I'm missing that same piece Alex was and this is a brand new wheel from the factory. The head parts guy and the guy that owned the dealership were one of the last people there when I picked it up, we've been talking a lot over the past two weeks tracking down parts. I kept telling them that is is supposed to be a magnet and it says do not put a magnet near this piece. Well all the warehouses were closed so left for home... anxiety was through the roof. I was starting to think that if they couldn't get it in in time for me to leave I could have them ship it to Jacksonville for me and I'd get it there but remembered all the commotion about how hard it would be to remove those torx screws. So I got my tools out and started to try. As I looked at it closer I started to wonder how those screws being recessed would even hold so good once the pickup was mounted, it seemed like if it was really that tight it would bend the metal on the sensor. That is when I stuck my finger in there and noticed the plate covering the magnet.

I still have so much adrenaline running through me I can barely type but damn I feel SOOOOO much better!

:rofl: :rofl: :rofl:

Excellent training for the stress roller-coaster you'll be going through during the actual rally. Being on the sidelines sucks, but sure is entertaining at times.

Alls well that ends well. Glad that is one less thing out of a bazillion you have to worry about.

And that new rear wheel sure looks pretty. I won't ask how much all that cost.

BTW, what is up with that weird looking braket rotor? Just missing black paint in the center diameter?

 

[Slonishku]

That's pretty damned funny!

My rotor finally showed up, all safe and sound. The junker even found the original bolts. It turns out they are 10mm in length. Still M5x0.8 threads. The actual head is very small (smaller than a typical Phillips drive buttonhead), and takes a T25 drive.

All mounted up and locktite in place. I'm headed to Home Schleppo after work to get some particle board and styrofoam sheets to get it all packaged up. A couple of dozen miles tonight to ensure all is riding well, then it gets shipped off. Yippee!
