    Default cast with 308

I then pre heated to around 275-300(any hotter would have caused the ATF to flame up). I stirched about an inch at a time and immediately peaned it and jumped to a different spot and repeat. I had one small pinhole to fill and that was it. I post heated it a bit and then covered it with a blanket and let it cool. No pinging, no cracks. I used Ni99 for the whole procedure. I reassembled and did a test run in 3rd gear over lots of rough stuff and no leaks so as of now it's good. Thx for the help guys. Dave

    Default How long it lasts

    I own my own heavy equipment repair business, previously have worked for 2 dealers and have over 15 years in the business. Unless the cracked was caused by impact, it is going to crack again, and it will be soon. Cases do not just crack, there is a reason for it, no matter how good of a welder, unless the issue is found the case will crack again. I would be looking for vibrations in drive line, worn bushing, misalignment, something, Or internal. Did a shift fork bend, something let loose or ready to let loose. Cast iron cases are extremely strong, they only break when something is wrong, or very early in the life of the machine.
