I take it the "rubber mounted hydraulic fittings" are the three (2 on the left, one on the right) 3/4 inch pipes sticking out the sides. They're not really rubber mounted, they screw into the sides of the pump unit ("Liftall" is Farmall's name for it.). The rubber is mostly a dust seal.
I'm not sure about "the plate that covers the pump." There are four bolts in the bottom of the clutch housing that hold the pump in, the part they go through is actually the bottom of the pump unit itself, not a cover. Are you sure the vibration is causing the bolts to loosen and not the other way around? That is, have you tried tightening the bolts to see if that helps?
Also, there is a sort of sheet metal cover at the rear of the Liftall that's secured with two bolts. If you take that cover off you can look up inside to see the drive shaft that connects the Liftall to the transmission. You could look to see if the shaft is wobbly, if the connection looks right.
If there's nothing obviously wrong, you may need to take the pump out and have it openned up to find an internal problem.
Good luck, Wm
