Look at the bearing in the pic.......
If you look you will see the outer race is installed with the thin side out, and the inner race has it's thick side out.......If you were to flip the bearing over, the outer race thick side would be outside and the inner race thin side likewise....Does it make a diff?...I dunno in this application, but often it does....It depends on thrust loads, but there should be no axial thrust generated if the spacers are installed correctly.

I'm the first to admit I may not understand axial thrust also.
BTW - It looks like the *** part number for the bearing is 559763. The other part# appears to be HD's number for that part. Could be wrong though.

RE: IDS Bearing failure
Yeah, those are the numbers I perceived/saw on my new hi-res laptop screen, but they don't cross on the *** bearing site.....They are still rather fuzzy, tho...You are correct, the other # is an HD number which does me no good.
You are most correct that the belt pulley should not experience side loads....The bearingshould be clamped by the spacers only at the inner race like the wheel bearings and thusly then be like it was a part of the axle where the inner race is stationary and the outer race revolves around it with the pulley...it should be a kinda tight/slip fit on the axle, but an interferance fit in the hub bore....The only loads on the bearing should be radial in nature and limited to the torque applied by the belt/tranny plus belt tension.
So far all I can deduce is possible installer error where they might have damaged the bearing from improper install tactic or getting the inner spacer confused with the outer........The only other possible cause so far is simply a poorly made bearing or the wrong bearing design for the application.
I really need folks to help narrow it down by supplying the extra requested info......Who installed it, did they use the HD tool set to install it, and also was it an '08 or '07?
you gotta remember that this device was designed/intended to absorb shock loads from the engine/tranny.....It might be that the bearing needs to be more substancial with a larger/thicker inner race...that would require it be larger in diameter overall.......I'd like to see the V-Rod pully bearing and compare them.....The V-rod makes much more HP, so if they use similar sized and design bearings, then it must be related to install or something else.

RE: IDS Bearing failure
Alot of owners now have this setup installed on 07s and all the tourers in 08.I would say so far if indeed its a problem its very very limited and probably due to the person that installed it.The kit made no reference of brg side direction.Someone posted that the tq values on attaching bolts to wheelhas been increased to 80 ft/lbs.Have yet to see anything in writing,if true the message boards are going to have to get this word out because not everyone had their local dealer install these kits.Several here work at dealers,factory,and if the tq values have been changed maybe they could post.Im sure HD wants this enhancement issue to go away.

RE: IDS Bearing failure
80 ft lbs is true - a new bulletin and saw a copy posted yesterday - no search function so I'll go hunt manually and post a link if I can find the string again...

The instructions don't say which way to flip the bearing when you install it.....That's maybe an omission by mistake.

Come on guys,post the details and more pics...........I'm a commissioned Boiler Inspector and pretty good at failure analysis.....We have the answer. All we have to do is share the details to sort it out.....If HD discovers it, odds are we will never hear about it.

RE: IDS Bearing failure
Iain't no expert, butI did a failure analysis on the old r22 toyota cam chain tensioners once....The aftermarket ones were hydrolocking and causing accellerated cam chain wear.....I bought one and cut it apart and fingered out the problem....The guy buying them from China for resale here had them redesign and experienced no more recalls/returns.
Usually, it it leaks, stinks, or squeaks i can fix it.
...Or break it trying.

Ok, I'm confused about one thing. In the picture below it looks like the part with the rubber isolators gets firmly bolted to the wheel hub with the 5 bolts. What secures the actual pulley part to the part bolted to the wheel hub?
I'm assuming the bearing gets pressed into the opposite side of the pulley, the spacer gets installed in the side of the pulley that is shown in the pic, and the washer goes between the pulley and the part bolted to the hub. I couldn't quickly find the install instructions to confirm this, but that's what I see by looking at the pic.
So my question is, what hold the pulley to the part bolted to the hub? Is it just the pressure of the pressed in bearing against the wheel to swingarm spacer? God I hope not.

As for the bearing failure thing, well I'm sorry for those involved but I won't be sounding any alarm just yet.
Any bearing can fail for any number of reasons, and if you make enough of any items, one of those items will fail/break sooner or later.
