10.22. Check of hydraulic pressure of GUR


Check of hydraulic pressure of GUR

Do not block the locking valve of a manometer more than for 15 seconds at the working engine! Do not hold a steering wheel in extreme provisions more than for 15 seconds!


 PERFORMANCE ORDER

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

The engine should work at completely open locking valve in order to avoid excessive temperature increase as a result of pressure lifting to a maximum level.

  1. Lift engine turns to value 1000 in a minute and make pressure measurement, having quickly turned a steering wheel from an emphasis against the stop in both directions.
  2. If as a result of check the maximum nominal rate (is reached see. Specifications), therefore, the system functions normally. At excess by result of measurement of the maximum value check 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 the locking valve and repeat check, pressure lifting to a maximum level testifies to malfunction of the steering mechanism, otherwise believe the steering pump — do not block the locking valve more long than for 15 seconds in a row.
  3. Disconnect a manometer, remove a nozzle and restore initial connection of hydraulic lines.
  4. Pump over a hydraulic path of GUR (see. Pumping of a hydraulic path of a steering drive).
  5. Check level of hydraulic liquid, in case of need make the corresponding adjustment.
