During a tire change my dealer called me to let me know it was going to take a couple of more hours for my bike to be done. When I asked why the delay, they explained how they were waiting on the bearing puller from the main dealer. Looks like the tech inspected the bearings while the tire was off the bike and found them both to have a funny play. You can really feel it when spinning then back and forth. Has this happened to anyone? Could they have just been bad from factory? I only have 3500Miles on the bike. BTW - stocker Dunlops only lasted me 3000 Miles. | ||

That's about as much as you'll get out of sticky sport bike tires... I get about 2200 with whatever I put on the back, and about 6600 out of a front. Discount motorcycle tire online is good for prices and shipping time. | ||

I did the deal where all I pay for is the mounting. I'm only paying $85.00 every time I need a new tire for the next 4 years. I guess that would be the next 3.5 now. | ||

my rear one's are stuck ( no play but there all mosts locked ), but after 20ooo miles who's to blame  | ||

I've seen one updated rear bearing fail, and I also know of one person who went through 4 sets of updated front bearings. He finally figured out that the spacer tube which sits inside the hub (the bearings ride against it) was deformed and would cut the seal of one of the bearings. It probably wasn't keeping the correct amount of load on them either, but the end result was once he replaced the spacer he's never had another problem. | ||

The front wheel bearings (orange seals) went on my 04XB12 before 10,000 miles, replaced under warranty. I'm now suspect of the rear ones, I can feel a graunching vibration when the rear suspension compresses during large dips in the road. Will check the rear bearings first. | ||

I had the original "black seal" bearing replaced at 800 miles, front and back. 300 miles later, the front recall "orange set" were replaced again. Dealership worked on this with no issue. Kudos to Augusta HD. | ||

That's weird. I never had to replace the bearings on my S3T and I put 31000 miles on it. I'm not as frisky a cornerman as most you guys are by a long shot but dang, 3500 miles? Bob | ||

Different bearings, different bike. | ||

Comin' up on 30,000 miles on the original orange bearings. I check them at every tire change, no problems so far. | ||

I removed the rear wheel on the shop XB recently, the bearing fell out on the ground at the same time. The wheel is roached, has about .002 clearance on the OD. Bummer. Tat had the wheels powdercoated before I bought American Sport Bike (the bike came with the biz), so the bearings had been removed at least once. Not sure if it had been twice due to the bearing non-recall. Not sure if proper installation methods were used. The bearing is not notchy at all, so it isn't a failed bearing that caused the bore failure. I'm going to talk to NTN about having a special bearing built with a slightly larger OD. This is an option that shows up in their part numbering scheme, so it may be doable. Whether it is doable for the quantities I would buy is yet to be determined. However, I need some help. I need to learn everything I can about the black seal bearings that were "recalled" (yea, it wasn't really a recall, it was a "performance upgrade" , as well as the ones that are in there now. Buell can't/won't tell me, citing product liability reasons, so I'm on my own here. Does anyone have one of the failed black seal bearings? If yes, can you please look at it and tell me all the markings that you find on it? There is minimal info in raised lettering on the seal but there is also likely some info etched on the outer race OD surface. Look carefully, it's hard to see. On the orange seal bearings, the info says (for rear) 6006LU, but it is actually a 6006LLU. LU means a particular kind of seal on one side, LLU means that same seal on both sides. The outer race says Taiwan C3, which means it is manufactured in Taiwan and has C3 internal clearance specifications, which is one size looser than "normal" clearance. From what I've been able to determine, looser clearances are used in higher heat applications where the expansion will cause normal clearance bearings to bind, and tighter clearances are used for high speed and precision tolerance applications (i.e., a router spindle, for instance). Some Yamahas use this same bearing in their wheels, and they also use C3 clearance specifications. Were the black seal bearings sealed on both sides? Did they use C3 clearance specifications? What exactly was wrong with them that caused their failure? Was it the wrong tolerances? Bad seal specifications or materials? Bad batch from the manufacturer? It is my intent to add the bearings (non taiwanese, at that) to the American Sport Bike catalog, in both stock OD and a slightly expanded OD for when wheels have had a spun bearing, but I want to get it right prior to doing so. That means spec'ing out the right bearing grade. I doubt these have ABEC3 or better specifications, they would cost much more if they did. I'm guessing that the orange seal was specified by Buell to help administer the "non-recall" program, but it MAY be indicative of a different seal material itself than the standard seal material. Any input is appreciated. One other note: The tube frame bikes had two bearings on the pulley side of the rear wheel (the one that failed on the shop bike). The XB has but one. It IS a much larger bearing on the XB, but I'd bet the press-fit bearing/wheel bearing area on the two tuber wheel bearings was higher than on the single XB bearing. And the tube frame bikes did not run a taught belt like the XB's do either. I'm sure that there was a fair amount of engineering time spent here by Buell, and I hope that my failure is an isolated incident traceable to poor installation technique, but I do have concerns that the failure on my shop XB may become more widespread as XB's rack up more miles. No fact, just a concern on my part. I hope my concerns prove to be unfounded. thanks, Al |
