The power-steering is adjusted on a Massey Ferguson 165 by adjusting the pressure in the power-steering system. To do this, first you will need to identify the two hydraulic lines that lead to the power-steering pump. These two hydraulic lines are labeled “input” and “output.” The pressure must be adjusted on both of these lines. The input line will control the speed of the steering, and the output will control the firmness of the steering.
Using a pressure gauge and an adjustable pressure-regulating valve, you must adjust the pressure in the power-steering pump. To adjust the pressure on the input line, start by setting the pressure-regulating valve to its lowest setting. Then slowly turn the valve counter-clockwise to increase the pressure until the desired speed of the steering is achieved. Once you have adjusted the input line, you can then adjust the pressure on the output line.
To adjust the pressure on the output line, start by adjusting the pressure-regulating valve to its highest setting. Then slowly turn the valve to decrease the pressure until the desired firmness in the steering is achieved. Once these adjustments are complete, you can then check the system for proper operation and enjoy the improved Power Steering on your Massey Ferguson 165.
