Flywheel side bearing race working its way off crank & pushing through seal , leaving bearing on the p#$$. Any ideas of the cause & how to rectify the problem ?

HB stage 4 P200 kit , HB fettled crank , B8es plug , 4% oil .

Depending on how worn the crank is where the bearing sits, you may get away with some bearing retainer.

And if the crank is buggered anyway, you could try a fairly liquid high temp epoxy to glue it into position.

Got the very same issue on my tameni T5 crank. Race was easy to fit on the crank shaft. Usually it needs a certain amount of strength to shove it down. Crank and bearing were brand new and I tried another bearing just to see and it the very same prob. Shaft was a bit to narrow. I glued the whole thing with a big amount of Loctite 648 and it never happened again....
Size matters!

there are bearing grades of loctite, but i`d be tempted to go for a new crank and bearing
