Needed to replace the front wheel bearing on my 67 Hornet and the 1967 parts booked called for # 41-6016 and Baxter’s, Steadfast
and Classic British Spares all showed unsealed bearings. So, I ordered a pair thinking that’s what’s in there. When I went to remove the bearings they were sealed so there are no “oil retainers” for the unsealed bearings. I went back to the 67 parts book and the picture showed sealed bearings which I didn't notice before. My 66 parts book shows unsealed bearings with the oil retainers.
How important are these oil retainers as the bike will be seldom ridden and only on short rides?
