Hi,
Have you decided why the bevel box bearings needed replacing?What was the cause of the failure?Was it badly assembled in the first place?Did the black goo that MMC in there wisdom used to "lubricate" the box from new cause the issue?
Or is it simply that the belt drive puts too much lateral stress on the output shaft bearing.?Im sorry if im posing a load of questions but I am sure my BB will fail at some time and your opinion and experience will be welcomed by all.

Regards David
