progress, holidays over, all the best 2016 wishes to all of you, drive safely.

finished the axial setup today
had the previous engine a genuine bronze axial bearing, this one will have to do with plain alu, with some alterations.

old engine; needle roller not supported on the outside, axial bearing press-fitted into the old main bearing hole. see previous posts
new engine; needle roller supported on the outside by a 4mm ridge, alu axial bearing plate loosely fitted.

as the old timing side bush + bronze insert is 4mm thick, I made the alu bearing out of a 4mm strip. It lies slightly raised above the timing side main casing material.

end float, negligable but all turns freely. casings will expand more, so no problem. actually my ducati has an negative end-float when cold.

regards A
