11.4.2. Check of a pressure of the steering pump

Petrol models

Preparation for verification of the pressure head characteristic of the steering pump (petrol models)

1 — the Air inlet
2 — the Broad hose of a pressure head path

7 — the GUR Tank

Verification of the pressure head characteristic of the steering pump (petrol models)

2 — the Broad hose of a pressure head path
3 — the Transitional line
4 — the Connecting union

5 — the Manometer
6 — the Locking valve

 PERFORMANCE ORDER

  1. Remove an air inlet (1).
  2. Pump out liquid from the GUR (7) tank.
  3. Disconnect a broad hose (2) from the steering pump, - prepare for collecting the spilled liquid and connect instead of it the transitional line (3).
  4. Connect the union (4) to a broad hose (2).
  5. Connect the manometer (5) to the transitional line (3).
  6. Between the manometer (5) and the connecting union (4) turn on the locking valve (6).
  7. Make sure that the connected components do not adjoin to moving components in a motive compartment. Check reliability of nipple connections.
  8. Fill in in the tank of the steering pump (7) necessary quantity (to normal level) hydraulic liquid.
  9. Start the engine and lift its turns approximately till 1000 a minute.
  10. Close the locking valve (6) and consider indications of the manometer.

Try to perform necessary procedures as soon as possible in order to avoid a liquid temperature overheat!

  1. Kill the engine, pump out liquid from the tank (7) and disconnect the measuring equipment.
  2. Restore initial connection of all lines, modify liquid level in the GUR tank (see the Head the Current leaving and service), then remove air from a hydraulic path, having several times turned a steering wheel from an emphasis against the stop.
  3. Check nipple knots for existence of signs of development of leaks, in case of need tighten nuts.
  4. Establish into place an air inlet (1).

Diesel models

Verification of the pressure head characteristic of the steering pump (diesel models with the M612 engine)

7 — the GUR Tank
8 — the Broad hose of a pressure head path
9 — the Connecting union

10 — the Transitional line
11 — the Manometer
12 — the Locking valve

Preparation for verification of the pressure head characteristic of the steering pump on diesel models with the M628 engine (1 of 2)

1 — the Air cleaner
2 — the Cover

3, 4 — Screws

Preparation for verification of the pressure head characteristic of the steering pump on diesel models with the M628 engine (2 of 2)

6 — the Screw
7 — the GUR Tank

8 — the Broad hose of a pressure head path
