HD/Buell has released a service Bulletin (or some such thing, TT 211 dated 9/16/05) that updates the torque spec for the Flywheel sprocket shaft nut on 2003 and later Buells. This is the one that holds the rotor to the flywheel output shaft. The previous torque spec was 190-210 Ft-lbs. The new Torque spec is 240-260 Ft-lbs. Use a flywheel locking link when doing this. See http://www.americansportbike.com/shop/cgi-bin/cp-app.cgi?usr=51F4562168&rnd=9379 929&rrc=N&affl=&cip=71.136.94.36&act=&aff=&pg=prod&ref=16075&cat=&catstr= | ||

Hrrmph. Interesting, I followed the spec on my tuber and had that nut back off. I always figured it was because I was not careful enough cleaning it before applying the recommended loktite. I still could have done something wrong, but when I put it back together the second time I used the upper end of the spec. And squinted a little and looked at an angle, and kinda bumped it a little tighter sort of by accident a little extra, when reassembling. | ||

Everyone would be wise to update their service manual with this number. My Uly backed off it's nut, and while I haven't opened up my XB9S primary to confirm that it's nut is loose, I'm 90% sure that it is. Now that I've heard what it sounds like when one is coming loose, I'm pretty darned sure mine is not tight. And according to Terry (Parsley, from Vallejo), the change from Timkin rollers to ball bearings on the flywheel output shaft makes that nut being tight even more critical to the end play requirements on the lower end. Terry thinks his Uly nut may be loose as well. I'll update here after I've checked it on mine and heard back from Terry. Al | ||

So, what does it sound like? | ||

I'd be obliged to anyone who can send me a digital copy of the service bulletin for posting on BadWeB. Please email to... BadWeatherBikers.com at GMail.com | ||

My Uly backed off it's nut Was you Uly manufactured after the 9/16/05 date of the service bulletin? I'm assuming mine, with a Nov 2005 sticker on the side has the newer torque value, but I'd like that confired somehow. | ||
| 2hogs |
Jlnance has a point. Is it reasonable to think bikes built after 9/16/05 have the new torque spec? Cheers | ||

So is this something that should be done asap , 260 ft lbs , whoa nelly . I have never seen torque # like this for any motorcycle . Something does not seem right here. 05 Cross , manufactured 9/04. | ||

Tought so myself ??? Make use to put BLUE Thread Locker on the CLEAN THREADS !!! In BUELLing LaFayette | ||

210 pound foot = 284.721 769 92 newton meter 260 pound foot = 352.512 667 52 newton meter Sounds strange to me. My biggest torque wrench is limited to 300 Nm.I have to push it hard to tighten the 270 Nm,my 2002 manual recommends. Is this new recommendation only for XB, or for tubers as well? | ||
| Sokota |
Has anyone actually torqued this nut to 260 ft lbs. scary number...crankshafts are expensive and a pain to replace. Red locktite , 260 ft lbs torque , thats insane. Maybe specs for the harmonic balancer on the HMS Queen Mary... | ||

My Uly backed off it's nut. I have been hearing noises for the last 3 weeks. It took a lot of convincing to get my dealer to check it out. Got the bike back today. Sounds a lot better. The dealer tried to blame me for not doing the 1000 mile service correctly and not adjusting the primary chain. He said that is why the nut came loose.

Rkc..just had my Ss in for the 1k svc..start it up outside the dealer & it was bangin' away!..I thought they spun a bearing on me...  Turns out it was this nut..nearly completely loose..lucky that it happened there & not on the cold ride home! | ||
| Blake |
This needs to be addressed via a free servicing for all affected XB12's out there. Please Buell, don't let this explode into widespread problem. | ||

| Bodyshot1 |
well..the two young "Buell" guys had no idea what the problem was..even brought another new bike around to listen to that motor..???..embarrassing, really..  the ol' crusty Harley guy threw it up on a lift took the case off..showed me exactly what the problem was..cuz he had seen it before..and fixed it up...so I wouldn't generalize too much. | ||

"My Uly backed off it's nut." Not good. " I have been hearing noises for the last 3 weeks." Not good to wait that long. " It took a lot of convincing to get my dealer to check it out." It shouldn't be that way, that dealership needs an attitude adjustment in the way of customer service. " Got the bike back today. Sounds a lot better." That is good. " The dealer tried to blame me for not doing the 1000 mile service correctly and not adjusting the primary chain." The nut that backed off is not part of the 1000 mile service check. " He said that is why the nut came loose. " That analysis is proof of the dealership needing an adjustment. A Service Manual and a decent set of tools does little to educate the marginal to bad dealership experience, but does wonders to help improve your ownership experience.

Hey all, Welp, I was just reading the thread here and I have noticed on my bike a loud hammering sound. (even over the race kit exh.) I been waiting on my service book to get here before taking it apart and I made a small adj. to the primary. It seemed a lil loose but no change in sound after the adj.. When the nut in question goes loose, (feeling through the inspection window with finger) would the slop be in a rotational direction or side to side. I am getting what seems to be rotational only. And there is a definate clunk at the end of it's travel. Very little movement but a clunk for sure. Blt. Oct. 04 XB12R | ||

Could someone please tell me if this event-and "knocking" sound -can occur on tubers? My 99 S3t has what I have always thought was one slightly loud front exhaust valve-but not quite- if that makes any sense. Primary chain adj. is per BadWeb suggestion. Reading this thread got me curious if anyone's run into this on earlier models. Thanks,ya'll.  | ||
| Blake |
I doubt you'd confuse loose pinion shaft nut with a noisy valvetrain. But the answer to your question is a definite "yes." Certainly wouldn't hurt to check it out. | ||
| Reepicheep |
The loose front primary sprocket nut sounds more like a crank problem, but it is definately a knock. The telltale giveaway is that it goes away when you let the clutch drag a little (just enough to load it up, not enough to move the bike), and that it has a kind of "ring" to it with each knock. I doubt crank problems ring like that. It really sounds awful, scared the crap out of me when I heard it, I thought for sure my engine was toast (until I noticed I could make it go away by loading the clutch, that's when I started figuring it out and just rode it home). | ||
| Blake |
Thanks Dago for the banner and suggestion to put it up and make it visible. I edited it a little bit. Put the torques right on it.  I wish we had a better copy of the actual shop bulletin! Anyone out there have one that they are willing to scan or send to me, please do. It would be most appreciated! | ||
| Buellistic |
97S3T's do not have that problem !!! | ||
| Court |
Just curious . . . . how come this has been out since last September and we, and presumably dealers, are just now getting wind of it. Also, do we have a copy of the actual bulletin? We need data. | ||
| Az_m2 |
My dealer knew nothing of this and could not find any info about it in their system. I told them I would get the details and call them in the morning. Is this something that is covered under warranty? Is there a Buell contact number that i can give them? Appreciate any help. Chris | ||

>>>Is there a Buell contact number that i can give them? Yes. The guy in charge is CHUCK KENNEDY and he is RESPONSIBLE for Buell Customer Service. Something about this "JDLR" (just doesn't look right) and I have a bit of a problem believing this is a "from the factory" update. Do we know that this "increased torque" actually came from Buell? IT seems mighty strange that a potentially fatal update is such a mystery to dealers. I'm looking on the Buell website for something in the NEWS section suggesting that "there have been certain changes to torque values. Owners of Buell models (insert range here) should contact their dealer, with their VIN, to find out if their motorcycles need updated". One of the purposes of the internet is effective communication. Service updates should not be "classified information". Anyway. . . just my opinion. Give Chuck a call. I can't find a number on the Buell website, but it's buried here somewhere on Badweb. . I have a meeting to go to, but someone will find it and post it here. Eager to see how much validity there is to this. | ||

Just got off the phone with Buell Customer Service. Rep could not find any information on this using my VIN (nor could my dealer). Rep put me hold and spoke with a Factory Technician. Here's what she told me: > There was a torque specification change. > Change was communicated to dealers. > Under normal conditions, you should not experience any problem (old spec). > If you take your bike in for service or experience a problem, you should ask your dealer to tighten the nut to the new spec. > If your dealer has questions, they should contact Buell Factory support and a technician will explain it to them. > Work should be covered under warranty. Hope that helps . . . Chris | ||

Does anyone know the size of this nut? I picked up a new gasket, seal for the gear shaft, link to lock the primary and a 600 ft lb torque wrench. I have every conceivable metric socket but not so with imperial sizes. TIA | ||
| Blake |
1-1/4" | ||
| Djkaplan |
1 1/4"? Are you sure? I thought it was a 28mm deep-well. I couldn't find a 28mm deep-well (Sears only goes up to a 27mm deep-well) so I used the closest standard size I had, which was a 1 1/8" deep-well. |
