Hi ,I have a crack in the primary cover of my 74 850 Norton where the crank nut came off once. Can it be welded and polished out? If so , who would you recommend to do it , preferably in Canada. It is barely visible and only mists some oil. Thanks
It can certainly be repaired although there will probably always be a colour change visible on the site of the weld. The cover should be pre-heated and clamped flat or it may distort.If you are just concerned about the oil mist, it might be worth trying Lumiweld or something on the inside face or even a chemical system such as "Devcon" - It will certainly be strong enough.Rich.
