I'm about to do a rear wheel swap in my Chopper to replace the spoked rear wheel with a solid Fatboy rear wheel which I'm just cleaning up at the moment.

The replacement wheel I've been told is out of a 2000 Fatboy, and has sealed bearings to suit my 3/4" axle which is great.

My question is, am I missing some large washers that sit against the wheel bearings that my spacers will butt up against (like is the case on my spoked wheel with tapered bearings, show below), or do the wheel spacers just sit up directly against the bearings on these later wheels?

Ok I've made up my spacers and just got hold of all the chromed bolts I need for the disc and sprocket, and am ready to bolt the whole lot together and get the bike back on the ground.

One last question though, should I be using blue or red loctite on these bolts when I put them in? I've been doing a lot of research into it for this application and while my gut instinct is to use blue, everyone is recommending red as the chromed bolts need that extra help and are more likely to back out than regular bolts.

When I first got this wheel the sprocket was still bolted to it and after getting the bolts out with a rattle gun we found evidence that red loctite had been used, so I'm confident my bolts could be removed in future.

I've decided to play it completely safe and in the end I've gone with red loctite, as I'm not taking any risks of them backing out and fouling on the lower left sissy bar mounting bolt as it's only 2mm away so that would happen before you know it.

Thanks everyone for all your input on getting this Fatboy rear wheel sorted. I've just finished putting the bike together and I'm real happy with how the rear wheel looks, much better than the old spoked wheel in my opinion.
