I posted a question, Nov 7, about my 580 se vibration at higher RPM. You wrote that I should check the front motor mount. I checked the motor mount and it is not there, the rubber is completely gone. Thank you for your expertise it is greatly appreciated. The backhoe is on my farm 240 miles from where I live so it took a while and weather to get to it. I have several questions, when I attempted to change it. I can not lift the engine high enough to change it, the hydraulic pump will hit the radiator. Do I have to remove the pump or can I move it forward and will the fluid need to be drained and lines disconnected? I have all three mounts to replace. My other options are to have it done, Southeastern in Indy is 100 miles and Southeastern by Cincinnati is fifty miles. I would have to hire it to be moved. I stopped at the local New Holland dealer, I could drive it there, they said they could do it but haven't done a Case. Cost wise I would rather do it myself. Once again thank you for your help. Bill
