my dealer is waiting on my rear wheel bearings and i was wondering if those bearings are the same as any other harley or buell??? Jake | ||

same as Buell 2008 front 1125R E0004.02A8A 2008 Rear 1125R E0005.02A8A 2008 front 1125R/CR E0004.02A8B 2009 Rear 1125R/CR E0005.02A8B 2009 Front XB12R E0004.02A8B 2009 rear XB12R E0005.02A8B | ||

You can get suitable bearings from any industrial bearing supplier. The rears are 6006 2RSC3; the fronts are 6005 2RSC3 (standard sealed ball bearing nomenclature). SKF and Koyo are suggested brands. See Uly wheel bearing threads for more info. | ||

Cant understand why a C3 clearance code is specified, C3 implies quite a high internal running clearance between rolling elements and cages and is ussually used where high operating temperatures need the extra clearance for expansion. Wheel bearings do not usually get that hot. I intend to take my bike for a long run and then measure the bearing temperture, this will then determine whether standard clearnce bearings are more suitable. | ||

John- I don't know why they specify the high internal clearance, but surely there must be a reason. I'm an ME but have next-to-no bearing design experience. Some of the posters on bearing threads in "Big, Bad, and Dirty" had extensive bearing design experience and might be able to answer your question. | ||

Just cant understand why C3 for the reasons given. As a mech design engr of rotating plant the choice of bearing code is essential and in 35 yrs of bike riding etc have never had wheel bearings run at the temps C3 would be applicable to. This includes track days on my GSXR 600 SRAD, was on a track day last month over here in UK and the wheel bearing were always cool to the touch, I checked them after each session. I am sure Buell MOCO has good reason to spec C3 but I can't see why at the moment. Given that the alleged frequent preamture bearing failure could be down to incorrect axle torque possibly damaging wheel spacers I am paraonoid with regard to wheel bearing longevity on all my Buells which was never a problem in my past non Buell life |
