Probably a ninny question, but. The bearing I have taken out of the swivel joint has a cage both sides to stop the rollers from escaping, but the new replacement one only has a cage one side thus allowing the rollers from escaping the other side if the are not parallel. The new bearing was supplied with an inner race, which I guess I don't want and I throw away. Two questions arise; first, have I got the correct replacement bearing (can i get one with cages both sides?) and secondly, which side of the new bearing do I drift into the swivel joint (the cage side or the non-cage side?). Series 3 Lightweight. 1978. I'd be grateful for some guidance please............
