Crankcase repair? TIG?
« on: October 10, 2024, 07:55:13 PM »
So when I got my engine out if the frame 3 bolts were totally seized and I had to saw them off. Now I'm removing them from the crankcase one of them has expanded with corrosion so much it's cracked the aluminium. I'm thinking I need a talented person with a TIG welder? To be fair when I put a nut in there it has nearly 5/6 contact on the face.

Help, advice and options all welcome!!

Thanks for all the help and replies. On my way home last night I met a really nice guy that goes by the forum name of Bryanj who supplied me with a set of cases. Thank you very much that saves me looking for someone to weld my old cases.
