    Could he disconnect the rams and shore up the bed with pilings in the raised position?

    After re-reading post #1 it looks like rams are bowed as well. To fix it right and make it dependable he needs to find some replacement parts .
    Unless it's just a weekend toy , but if he counting using it on any site work you want reliable fixes .

    No it won't. That mechanical joint won't put enough heat into the end of the rod shaft to matter. If the cylinder rods are bent, that is another story.

    I would guess the M817 parts are interchangeable. Another option if the crosshead is symmetrical, flip it over, maybe spin the cylinder rods 180 as well. See if the bed will go all the way down and just run it...

    I kinda been chewin on this idea. Its already ruined, so its not like I can make it any worse I dont think. The crosshead does look like I can flip it, and who knows,..if i dont ever overload it it may work forever that way. I'm not gonna lie though,...having an excuse to buy that other M817 for parts is making my wallet burn

    I would take it off and find a shop with a BIG press and have them try to bend it back, then reinforce it. Safety note, be sure to hold the bed up with something.
    On my M929 the bed will go almost 90 degrees up.

    The 817 and 929 I have both have fold up bed supports that hold at about 45 degree, just for this purpose.
