© 200423 3-9 Inspection and adjustment STEERING GEAR, GENERAL ΧΦ65/75/85 series 7 2 Note: When the cock (4) is closed, the steering wheel should never be turned. The peak pressures involved could damage the pump or the test case. 3. Open the cock (4). 4. Compare the reading with the specified value, see 'Technical data'. Testing the pump output Activate the output meter (7) using the switch (8). 2. Set the engine speed to 1200 - 1400 rpm. 3. Close the cock (4) until the pressure gauge (10) indicates the specified pump output pressure. See 'Technical data'. 4. Take the pump output reading at the output meter (7) and compare this value with the specified value. See 'Technical data'. Testing the steering pump flow control valve Activate the output meter (7) using the switch (8). 2. Slowly increase the engine speed, until the output meter (7) reading no longer rises. Check whether the output is stable and compare the measured reading with the specified reading, see 'Technical data'. 3. Increase and decrease the engine speed and check whether the output increases evenly and then remains stable. 4. Slowly close the cock (4) until the pressure at the pressure gauge (10) has increased to approx. 50 bar. While closing the cock, check whether the pressure gauge (10) needle starts to fluctuate. Testing the internal steering box leakage Check whether the connection between the "Tank" connection and the steering oil reservoir has been established. The connection to the reservoir should continue to the bottom of the reservoir, to prevent foaming. 50 100 150 200 250 5 10 15 20 25 9 7 2 4 6 5 10 1 S7 00 020 50 100 150 200 250 5 10 15 20 25 9 7 2 4 6 5 10 1 S7 00 020 |
