4.7.15. Removal and installation of the engine

If the established hoses of naduvochny air are not fat-free also damp, it can lead to failure of a turbocompressor.


 PERFORMANCE ORDER

  1. Disconnect a negative wire from the rechargeable battery.
  2. Remove the lower protection cover of a motive compartment
  1. Turn out bolts and uncover the compartment EC).
  1. Separate the socket.
  1. Separate all sockets of electronic blocks (1 and 2) of a control system of the engine.
  1. Separate sockets (1 and 2) of the relay of candles of an incandescence.
  1. Remove the relay (1) with a socle and safety locks (2). Separate the socket (3), remove a protective cap (4), give a nut and disconnect a positive wire (5) of the rechargeable battery.
  1. Give a nut (1), wring out a clamp (2) and disconnect the diagnostic socket (3).
  1. Remove consolidation (1) and take out a box (2) electrical wirings the movement up.
  1. Wring out clamps (1), uncover a box (2) electrical wirings, extend a plait of an electrical wiring from a box and record it on the engine.

At installation pay attention to guides (3).

  1. Remove a cap of a conclusion of a positive wire of the rechargeable battery.
  1. Give a nut.
  1. Release collars (1), and release a positive wire (2) from holders (3).
  1. Remove the holder of oil pipelines of the transmission from the engine case pallet. Unclench collars of fastening of a positive wire of the rechargeable battery.
  1. Remove AT (see the Head Automatic transmission).
  2. Remove an engine cooling system radiator (see the Head of the Cooling system of the engine, heating, ventilation and conditioning).
  3. Press several times a brake pedal to reduce depression in the vacuum amplifier of brakes.
  4. Press a clamp (1) and at the same time disconnect a vacuum hose together with connection (2).

At installation check a sealing ring of connection and if necessary replace it. Disconnect vacuum hoses (2, 3 and 5) from the vacuum pipeline (6).


Vacuum hoses
  1. Turn out bolts (1) and take aside the vacuum pipeline (2). Wring out a clamp (1) and disconnect a fuel-supply line (3) from the valve of preliminary heating. Open a collar (2), remove a fuel-supply line (3) and record it on the engine. Disconnect the socket (4), press a clamp (5), disconnect the bringing fuel-supply line (6) and record it on the engine.
Connections of fuel-supply lines

Collect the following fuel.

  1. Unclench collars (1) and remove right (2) and the left (3) pressure head sleeves of naduvochny air.

At installation have collars on former places.

Hoses have to be dry and without lubricant traces.


  1. Weaken collars (1) and remove a pressure head hose (2) assembled. Weaken a collar (3) on the intercooler and remove a pressure head hose (4) assembled with a pressure head tube.

Hoses have to be dry and without lubricant traces.


  1. Weaken a collar (1) on the intercooler and remove a pressure head hose (2) assembled with a pressure head pipe. Weaken a collar (3) and take a pressure head hose (4) aside.

Hoses have to be dry and without lubricant traces.

  1. Remove a natyazhitel of a belt of the drive of the K/V compressor (see the Section Removal and installation of driving belts and their natyazhitel).
  1. Turn out a bolt (1) and unclench a collar (2).
  1. Separate the socket (1), turn out bolts (2), remove the pump GUR (3) from the top section of the pallet of a case and fix the pump by a wire on a beam of the forward bridge.
  1. Turn out a bolt (3) and release a wire (4) from the holder.
  1. Weaken a collar (1) and remove a hose (2) of nadduvochny air together with the pipeline of nadduvochny air.

Hoses have to be dry and without lubricant traces.


  1. Disconnect the soaking-up pipe (1) from a turbocompressor and take a little aside. Turn out bolts (2) fastenings of the K/V compressor, lower the compressor down and disconnect from it an electric wire.

Do not disconnect К/В system pipelines.


  1. Give a nut (1) and remove a wire (2) weights. Give a pillow nut (3) support of the engine and disconnect a vacuum hose (4) from the adapter.
  1. Unclench clamps (1 and 3) and disconnect water hoses (2 and 4). Tie a plait of an electrical wiring (5) AT to a turbocompressor on the right side. Record a positive wire of the rechargeable battery behind a flywheel.
  1. Slightly raise the engine for lifting eyes and pick up the soaking-up phone (1) in the direction specified by an arrow.
  1. By means of the special elevator take the engine from a motive compartment for forward and back eyes up.

Do not damage components in a motive compartment during raising of the engine.

  1. Installation is made in the sequence, the return to an order of dismantle of components.
  2. After installation before start of the engine check levels of working liquids and if necessary modify them.
  3. After work between the fuel tank and TNVD it is necessary to pump over a fuel supply system to avoid work of TNVD in a dry state and its damages. For removal of air execute the following operations from TNVD:
    1. Disconnect the bringing pipeline from TNVD;
    2. Include ignition;
    3. Wait for a fuel exit without bubbles and switch off ignition;
    4. Install the bringing pipeline with a new collar.
  4. Start the engine and make sure of lack of leak of fuel and working liquids, and also of lack of abnormal noise and vibrations.
  5. Let's the engine work on single turns, then muffle it and again check levels of working liquids.
