Just sitting here hoping to get fed shortly:333 is the CB350 Four part and according to CMS 52141-333-000 also fits some CB400 fours.But notice that some CB400 fours call up 52141-369-000.The 333 version shows holes for grease to come through, the 369 does not show the holes as probably doesn't need them as the grease is fed from S/A nipple.Maybe otherwise the same.
Pretty sure I have a NOS CB400F collar that I paid an arm and a leg for a few years back. I'll have a dig around and see if I can find it!
