Here are some photos of repairing the hole in my tractor crankcase . Welds
looked kinda ****ty , but this is a piece of aluminum that's been soaking in

one I bought* back and use this one .

* They used a power disk sander to remove the gaskets and sealant from the
precision machined sealing surfaces ...
