CHECK FOR CONCRETE IN VALVE AROUND TENSION SPRING,OR THR BIG BEARING AT REAR OF HOPPER,EVERY PUMP I,VE EVER RAN SHIFTED HARDER ON ONE SIDE THAN THE OTHER,VIBRATION IS EITHER FROM METAL TO METAL ON CUTTING RING & SPECTACLE PLATE OR FROM YOUR MAIN BEARING. 

 Normal procedure for setting up a putz was to open outriggers and level pump.By doing this the hyd. oil was warm enough to cycle the pump without frying a feed pump.The pump was then cycled at a medium speed and pressured out on both sides by way of the "disturbance" switch.This seemed to even everything out.A putz can also have a problem with "changeover" Ideally the the speed of the delivery cylinders should accelerate greatly for a microsecond which enables a smooth "shift".Test this by cycling the machine at high rpm,and low delivery cylinder speed.With the protective guard on the water box,watch your pistons as they change direction,you should see rapid acceleration when the piston changes over.This is controlled electronically.Putz has alot of variables that dictate how a machine acts that can easily be worked on by any semi-competent "mechanic".I now operate a sch----,in which all I do is sweep the floor-board....and plug in the hopper light

Ok it looks like the question was deleted, and that is ok. From the answers that are left up and anyone tell what the question was for 100. lol
