Nieskes Posted January 19, 2014 Report Share Posted January 19, 2014 How does it look from the inside? Got any pics? Quote Link to comment Share on other sites More sharing options...
Surfrjag Posted January 19, 2014 Report Share Posted January 19, 2014 If its structural i would weld it or get a new set.. Quote Link to comment Share on other sites More sharing options...
LCW Posted January 20, 2014 Report Share Posted January 20, 2014 I would weld it, but that may cost more than a good used set, unless you can tig cast yourself. Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted January 20, 2014 Report Share Posted January 20, 2014 If you Havnt been tig welding your self for years on aluminum, it's cheaper to just find another set of cases. But the more important thing to know is why the cases cracked. Was it a boulder or is the tranny wanting out? Quote Link to comment Share on other sites More sharing options...
monster Posted January 20, 2014 Report Share Posted January 20, 2014 If the crack is in the trans housing from chain whack I've repaired the leak with Toyota FIPG black. Just clean crack and case with brake clean to get all the oil out and off the crack. Then pack the crack from the inside with FIPG with your finger it will come out to the outside of case. Then I smooth a 1/4" thick cover of FIPG over the top of the crack inside the trans. Clean outside off so looks good it will never leak again as long as you don't chain whack it again.
