This is kind of a continuation of my "Do wheel bearings last forever?" thread on the British Bikes in General forum, but it may now be getting specific to BSA.

I got the bearings out of the wheel tonight - both "locking rings" are right-hand thread as it turns out (and thanks to a definitive answer from L.A.B. on this), but I haven't cleaned them up yet.

The question for tonight is, I noticed in the Spares book that there is a piece on either side called "oil retainer", 67-5564 (right-hand) and 67-5563 (left-hand), between the locking ring and the bearing. In the picture they look like felt washers. My wheel does not have these; are they really necessary? (With open bearings, that is; I'm guessing they would not be necessary with sealed bearings.)

Are the p/n 67-5563 and 67-5564?

A quick google search shows a couple of different "dust seals" so I would think a sealed bearing wouldn't need these, but an open one would.

Yes those are the part numbers. I have open bearings now and no "dust seals" (or "oil retainers", as listed in the Spares book). I've owned this wheel since 1991 and used it since 2001 "as is".

I'm trying to decide whether or not to replace the bearings, and I'll be cleaning and inspecting them this afternoon. The lack of oil retainers may constitute another argument for replacing the bearings, and that with sealed ones.

After cleaning the bearings with kerosene, one of them feels a bit loose, so I guess I'll replace them. Might as well go with sealed bearings, since I don't have those "oil retainers".

What specifications would I have to know to source generic replacements for these bearings? These are the originals and are marked "RHP" and "LJ7/8".

Thanks, but it looks like I won't need those specs - CBS has good quality sealed bearings for a very reasonable price.
