STEERING 4.1 Neutral Adjustment (con’t.) Hydroback assembly 6 Loosen the 2 jam nuts next to the main body. (fig. C3555) 7 Turn the 2 nuts away from the main body of the hydroback. 8 Cycle the control lever several times. 9 Push the control lever rearward until you feel resis - tance. Stop. 10 Turn the 2 jam nuts back toward the main body of the hydroback until the nut just touches the flat washer. 11 Cycle the control lever again checking for a neutral position. If the lever returns to neutral, tighten the 2 jam nuts together. If the hydroback still does not center, the hydroback has internal damage or wear. Replace the hydroback assembly with a new one.

Make sure the loader is raised securely off the ground before restarting the engine. Angle adjustment C3555 Hydro Back Replacement Angle finder Replacing the hydro back changes the steering control lever angle. To correctly set the angle after the hydro back has been installed: 1 Replace the hydro back by removing the 2 bolts located at either end of the hydro back assembly. 2 Install the hydro back in the reverse order. Check the steering control rod ends and replace them now if they are worn.
3 Use an angle finder to check the base measurement angle the loader is sitting at. (fig. C3552) Note the angle the loader is sitting at. This measurement will have to be added or subtracted to the next measurement to give the most accurate adjustment. 4 Attach an angle finder to the most vertical part of the control lever. (fig. C3553) 5 Turn the hydro back threaded rod (fig. C3555) in or out of the female rod end to move the control lever to a reading of 0є. Be sure to allow for angle the loader is sit- ting at. (Base angle) Jam the nut against the rod end when completed. Make sure there is a minimum of 3/8’’ (6mm) of thread holding the female rod end to the threaded rod.
