Hydraulic checks

Check of adjustable pressure

 PERFORMANCE ORDER

 Preliminary it is necessary to estimate degree of deterioration of internal components and to make corresponding replacements (see above)!

In order to avoid damage of the steering pump do not keep the manometre valve closed, and a steering wheel turned out against the stop долее, than within 5 seconds!

All traces of a spilt hydraulic liquid immediately collect dry rags or paper towels!

1. Connect to manometre ST1 92511000 transitive hoses And and In (ST2: 34099АС020 and ST3: 34099АС010).
2. Disconnect from the pump a pressure head hose and instead of it connect transitive a hose In (ST2) measuring assemblage, - take advantage of a sealing lining № 34621АС021 and штуцерным a bolt № 34620АС010.
3. Disconnect a tube With from a tube from outside the steering mechanism and connect to it transitive a hose And (ST3) measuring assemblage.
4. Check up liquid level in tank GUR, make necessary updating.

5. Open the gate of a manometre and start the engine on single turns.

6. Consider the manometre indication. If the result of measurement exceeds limiting admissible value (981 кПа), check up a condition and passableness of hydraulic lines, make necessary corrections, replace the failed components.

Check of pressure of opening редукционного the valve

 PERFORMANCE ORDER

Block the gate and consider the manometre indication. Again open the gate of a manometre and consider its indications at a reversing of a steering wheel from an emphasis against the stop. If the result of measurement falls outside the limits an admissible range (9.611 10.199 кПа: for models 2.0 and 2.5 l/7.650 8.340 кПа: for models 3.0), replace pump assemblage.

Check of working pressure

 PERFORMANCE ORDER

Again open the gate of a manometre and consider its indications at a reversing of a steering wheel from an emphasis against the stop. If the result of measurement falls outside the limits an admissible range (9.611 10.199 кПа: for models 2.0 and 2.5 l/7.650 8.340 кПа: for models 3.0), replace assemblage of the operating valve with a leading gear wheel of the steering mechanism.
