Just out of curiosity, would the case suffer any distortion from welding? Would it have to be clamped flat along it's mating surface during the heating/cooling cycle?

I'm contemplating having some cases modified, and was just thinking of any possible implications.

I wouldn't weld anywhere near a bearing surface or mating surface. It can probably be done with ease but I don't know. When tig welding stainless the parent metal pulls quite hard. Aluminium may be different but I'm not too sure, best ask a metallurgist or very competent welder.

someone can shoot me down in flames, but could the metal putty stuff be used?

Otherwise you can always buy my MC18 crankcases that no one wants to buy! Rolling Eyes

Ive seen a Nissan Primera gear box welded up that hit a brick. It had a decent chuck broken out of it.

Im sure a professional would able to weld it up no problems. There is a fella up here in bris that welded my chassis when it cracked. I can send you his details if you like.
