- Illustrative material according to procedures of verification of the pressure head characteristic of the pump GUR is presented on illustrations to which all references which are found in the text belong.
- Open a cover (30g) and pump out hydraulic liquid from the tank of the steering pump.
- Disconnect from the pump a pressure head broad hose (30i) and connect to the last a transitional nozzle (038a).
- Connect a transitional nozzle to the union of the pump (038b).
- Connect the manometer (039) between transitional nozzles (038a and 038b).
- Fill the GUR tank with fresh liquid to the required level.
- Start the engine and lift its turns till 1000 a minute.
- Block the throttle crane (039a) and read out the indication of the maximum working pressure of the pump GUR from the manometer, - try to consider the indication as soon as possible in order to avoid risk of an overheat of oil. Compare result of measurement to nominal rate (see Specifications).
- Kill the engine and pump out oil from the GUR tank.
- Remove the manometer and restore initial connection of hydraulic lines, - do not forget to replace a sealing ring of the nipple socket of a broad hose (30i).
- Fill in in the tank the required amount of fresh liquid (see the Head of the Power supply system and production of the fulfilled gases).
- In conclusion visually check a hydraulic path of GUR for existence of signs of development of leaks.
