STEERING 4.1 Neutral Adjustment (con’t.) Hydroback assembly 6 Loosen the 2 jam nuts next to the main body. (fig. C1638, 2025) 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 positive feel. If you now have a positive 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.
2 Jam nuts Jam nut C1638 Rod ends 2 Jam nuts 4 Angle adjustment IMPORTANT Repairs or adjustment to the control lever system may change the loader neutral position. Make sure the loader is raised securely off the ground before restarting the engine. C2025 Hydro Back Replacement Angle finder Replacing the hydroback changes the steering control lever angle and the neutral position. To correctly set the angle after the hydro back has been installed: 1 Replace the hydroback by removing the 2 bolts locat- ed at either end of the hydro back assembly. 2 Install the hydroback 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. C4282) 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. C4283) 5 Turn the hydroback threaded rod (fig. C2025) in or out of the female rod end to move the control lever to a reading of 12є leaning forward. Be sure to allow for angle the loader is sitting 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. 6.
