Another thing that I did was to modify the metal body of the centa so that it presses better on the circular part of the crankshaft because it only pressed on the inside.

I have already used loctite 660 to repair the rear wheel shaft spline with NSU 1200TTS brake drum also with the splines a little worn, after X1000 km I was able to disassemble again with an extractor while heating to check the wear of the brakes I reassembled again with loctite 660, only by heating with a small butane torch without reaching 260°C it is well softened I think around 150°C.
