Control system of a full drive


  1. Establish the special tool on a hose for air, having connected it between the air pump and differential (actuator). Tighten against the stop an adjusting bolt of the special tool. Close a lateral opening for air check by means of a fuel hose as a deaf stopper.
    • Special tool:
      • (A): 09918-18110
      • (B): 09367-04002

Be careful not to bend a hose.

  1. Turn on the switch of ignition and switch the gear shifting lever from situation 2Н in situation 4Н.
  2. Check that the motor earned (its sound) within 1 second is audible and stopped, when the arrow of the device of the special tool showed the specified value of pressure.
  3. Check, whether there is no leakage of air. Pressure specifications: 30.0-45.0 kilopascals (0.30 – 0.45 kg/cm2, 4.25 – 6.40 pounds on sq. inch).
  4. Check, that the value of pressure shown on the dial of the special tool, fell, as soon as the lever of gear shifting is switched in situation 2Н.
  5. Start the motor, having again switched the gear shifting lever in situation 4Н. Weaken an adjusting bolt to reduce value of pressure on the device dial. The motor should earn and stop again in about 4 seconds.
  6. Having weakened an adjusting bolt of the special tool, switch the gear shifting lever in situation N or 2Н, and then in situation 4L or 4Н. The motor of the pump should stop approximately in 10 seconds after the motor started to work.
