People weld cast heads all the time.. could I get away with welding large portions of a transmission case? (902) I have a wacky idea that just might work...

Here's the thought.. Case is aluminum.. Twice as strong, conducts heat twice as well. Twice the weight too, but but compared to the internals it's not that big a deal. It'll be lighter than any 915/930/G50. The intermediate plate flange is thinner, but they're both hollowed out, and the 902 is aluminum, so it's stronger. One possible disadvantage is that the pinion shaft bearing is retained by 4 bolts instead of 6, I'm not sure if that matters much. So what I could do is cut out the offending sections of the case and weld in new ones a little farther out, so the ring gear can be flipped for mid engine use. I have had good luck welding cast aluminum before, but I don't know if it was a similar alloy or if I just got lucky. I would use a 914 ring and pinion. (902 output flanges are different, and I heard a rumor that the diff is weak) So there's my wacky idea, have at it! (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) |
