10.22. Check of hydraulic pressure ГУР


Check of hydraulic pressure ГУР

Do not block запорный the valve of a manometre more than for 15 seconds at the working engine! Do not keep a steering wheel in extreme positions more than for 15 seconds!


 PERFORMANCE ORDER

  1. Check up serviceability of a condition of a pulley and correctness of adjustment of a belt of a drive of the steering pump (Adjustment of effort of a tension of a belt of a drive of the steering pump see).
  2. Modify properly pressure of a rating of tyres.
  3. Disconnect from the steering pump a hose of a line of a high pressure, establish between the pump and the steering mechanism transitive nozzle KV48102500 (J26357-10), having connected to it manometre KV48103500/ST27091000 (J26357) (Check of hydraulic pressure ГУР see an illustration).
  4. Completely open запорный the valve and remove from system air stoppers (Prorolling of a hydraulic path of a steering drive see).
  5. Check up level of a hydraulic liquid in the tank of the steering pump, in case of need make corresponding updating.
  6. Start the engine on single turns for warming up of hydraulic liquid ГУР to temperature 60—80С.

The engine should work at completely opened запорном the valve in order to avoid excessive rise in temperature as a result of lifting of pressure to a maximum level.

  1. Lift turns of the engine to value 1000 in a minute and make pressure gauging, quickly having turned a steering wheel from an emphasis against the stop in both directions.
  2. If as a result of check the maximum rating value (Specifications see) is reached, hence, the system functions normally. At excess by result of measurement of the maximum value check up serviceability of a condition of the valve of management of a stream of the steering pump. If the indication does not reach the top border of an admissible range, slowly block запорный the valve and repeat check, lifting of pressure to a maximum level testifies to malfunction of the steering mechanism, otherwise believe the steering pump, — do not block запорный the valve longer than for 15 seconds on end.
  3. Disconnect a manometre, remove a nozzle and restore initial connection of hydraulic lines.
  4. Pump over hydraulic path ГУР (Prorolling of a hydraulic path of a steering drive see).
  5. Check up level of a hydraulic liquid, in case of need make corresponding updating.
