      So I just looked at my headstock bearing they’re in perfect condition look new but the top ball bearings there was a ball sized gap Is that normal or am I missing one? Next question the lower bearing cup is not a pressed fit like my husky is it supposed to press into the frame when the assembly is tightened down?

        Consulted my Haynes and I’m happy that the ball bearings require that gap, as for the cup it states it’s an interference fit I’m not sure if that’s the same as a press fit

          The bottome yoke has a taper roller bearing. The cup is interference fit into the frame, the roller bearings are interference fit onto the stem. The two tighten together. Be sure not to over tighten the triple clamps.

            @Calum I gotcha, but the cup moves if you touch it that said the cups new all the bearings are new there’s no play at all abs it’s smooth as butter I call this one good

                  Mine have all been hard to remove and secure when fitted, have you measured it against a known original. Will promote wear in frame seat if allowed to move even slightly

                      But are they the correct size was my point, worth checking?

                        @oldman it’s hard to say it looks like they were all changed together unless someone damaged one and had another lying around

                          @declan How much is a new set? If in doubt it would be wise to replace them, if nothing more than just for peace_of_mind!!! 😉

                            @NINJA only 20 pound but a bit of a ball ache to install when I have the money I’ll buy a set and just swap the bearing race out probably after it’s built up and finished though
