Any way to fix oil pan drain?

Like the newbie I am, I overtightened and broke the oil pan drain, half the threads broke off, is there anyway to fix it without having to buy a new motor? maybe weld or some kind of putty or something? Any help would be appreciated thanks.  here's a pic if it helps at all. BTW its a 2001 rm 80 if that matters.
 

Do you still have the broken peace?

yes I do.  

You can have the peace welded, drill the hole and put a helecoil in it or you can fill the whole thing with Devcon then drill and tap it. Its a pain but it will work.

hmm interesting thanks for the advice ill see if i could get it welded  

You dont weld this the normal way. Dont let the average garage guy do this.
You can weld anything you just have to find a welder that knows what he is doing.
Tell him what kind of meteral it is and you will know what im talking about.

would it be possible to fill it in with jb weld then tap a hole and use helicoil?  

well they do make a threaded sleeve that works very good. welding on pot alum. isnt the best idea.  epoxy or j.b weld wont do a very good job . probly find insert kit at fastener supply co. but let your fingers do the walkin. "yellow book"  

you can retap it the hole with larger thread and put a bigger nut in bolt in there. I think Pin-it on the board did it. Maybe PM him

easier still MOST cases have threads deeper than the bolt is long, find a longer bolt and presto ready to ride. welding not a good idea as it sometimes distorts the case and can cause seized shift drum or leaking center cases. one caution with longer bolt: if it is too long it will hit some rotating part in the tranny.
MOST drain bolts are tourqed to 12 to 20 foot pounds. if you dont have a tourqe wrench, GET ONE.
