    My old faithful manitou MT 425 needs work done on the rams that lift the boom. I have everything ready for the pins that hold the rams to be removed. We have been unable to get the pins to shift with a sledge hammer etc. Any suggestions??

    I have seen a guy using a large air impact gun pushed up against the pin. It moved it but not sure how stuck it was.

    Just wondering are the pins bent? Might have to wriggle them as someone else hits them. Any pics?

    If the seat's wet, sit on yer hat, a cool head is better than a wet ar5e.

    Pins seem perfectly straight, rams move slightly from side to side so it must be seized to the spacers and bush at the outside. Will get pictures later

    Spin the pins 180 degrees.

    The pins are seized solid!

    If beating sideways wont shift it, it's either rusted or worn a lip over time. Turning pins will either release them or move them to even up the wear and let them move.
    Weld something onto the end if things get desperate.

    Got sorted. Had to weld on a 30mm high tensile threaded bar to the end of the pin to make a puller with a slieve over it. Still took a 26lb sledge to move it as well as the puller!
