    Like the title says---why do i keep breaking my adaptor between my 465 and 208? I don't really mind that I broke it as i am going to be doing something diffrent, but what is happening that breaks the feet. If I am going to be spending a lot of $$ for a doulber what can i do to keep this from happening to the pricey stuff.

    check your motor mounts and tranny mounts... you have too much flexing going on in there somewhere.. maybe even park it on some wierd angles and crawl under it and see what it is doing.

    first time i broke it (same exact place) new motor mounts, poly tranny mounts.----this time same motor mounts (will check) and new rubber tranny mounts. first time i had a lot for frame wtist in front and rear, this time i tied in the front w. tubing and it feels REAL solid in the front. (had problems w/ clutch when twisted.) none whatsoever after tubing.

    The adaptor need's support all the way across the bottom of it, not just the edge's. Notice how it sheared off right at the mount to the adaptor? /forums/images/graemlins/eek.gif /forums/images/graemlins/eek.gif

    Build a crossmember that will support the complete bottom edge of the adaptor, and Your trouble's will be over.

    The bolt/bolt hole's only tie it down, it's a straight vertical line up to the side of the adaptor, where it sheared off.

    are those the bushings underneath where the tab is? or spacers..cuz my 465/208 dont mount like that... gotta find a way to distribute the torque load across the whole adaptor piece instead of just the ears..that way the stress will be more spread and less chance of breaking.. [​IMG]

    Mount will go under the entire length of the mounting leg.
