Anyone know if the transmission mounting ears can be welded back onto the tail housing?

I welded a crack in one ear on my freshly rebuilt race box just a month ago.
It requires pure magnesium filler wire. Don't gas weld it, TIG it. The technique is similar to welding aluminum but a little more difficult, using AC. Grind a groove with a carbide mounted in a die grinder. Use a stainless wire brush to keep the weld area clean. While welding it may fume a bit of white powdery stuff. This is normal. Be carefull not to overheat the weld zone. The puddle will have no strength and drop a snot which may catch fire. The casting has a lot of porosity which will end up inside the weld. You have to grind it out after welding and reweld in order to have any decent strength. This may be required a couple of times. |
