Hi All,
For future reference, Jim was kind enough to post pictures of my
broken right axle. I am in the process of collecting the replacement
parts, and include pictures of the taper style axle and bearing nuts
available from Bob Grunau (can't wait!).
It seems 8122 has had this repair previously; as you can see from the
side by side image I have two different styles of axle. One has a
machined surface, the other (good) side has what seems to be shot
peening.
The break is a classic fatigue fracture and really highlights what
Mike Sherrell outlines. I should also note that the right side had
gear oil inside the hub while the left was clean (fortunately no
damage to the brake linings). To me this suggests that the right
side had a looser fit and sure enough my hubs are different in size,
whereby the the right hub did not contact the outer race of the
bearing. I'll be making some shims up, so if anybody needs these
give me a yell.
Mike
