I'm installing new spokes on the rear wheel. I noticed that there is some pitting on the bearing race where water obviously has worked its way between the race and the bearing.

Should the race be replaced or is some slight pitting something that will not cause major concerns.

I cannot find any information about replacing the rear wheel race.

Any input is appreciated.

Thanks

If there's some pitting on

If there's some pitting on the race, the surface that the bearing is riding on, you'll need to replace the whole bearing, not just the race. I tend to treat a bearing and the race as a set.

Duane discusses these types of bearings on his website:

Same bearing I used for swing

Same bearing I used for swing arm is used for the rear hub. So I can use the Cycle Works race puller that I used on the swing arm.
Is there any thing different that I need to consider when I install the race that is different from installing the swing arm race?
I read one guy's restoration account where a spun rear hub bearing that needed replacing had to have a special shim, race, etc.
I hope that the procedure is as straight forward as the swing arm install.

Heat the hub. About the

Heat the hub. About the boiling point. Using the axle and an appropriate spacer, the bearing set should readily pull out.
It may be necessary to change the shim to accommodate the new bearing.
