Routine maintenance

Compression check


  1. Check up pressure of compression upon all four cylinders as follows.
  2. Warm up the engine.
  3. After a warming up stop the engine.

After an engine warming up put the gear change lever on "Neutral" (for models А/Т put the gear change lever in position Р), both establish a lay brake and block приводные wheels.

  1. Disconnect a cable of an accelerator (3) from a clip (4) (only for vehicles with the left wheel).
  1. Disconnect муфты ignition coils.
  2. Remove coils of ignition (1).
  3. Remove all spark plugs (2).
  4. Disconnect wires of a fuel injector from муфты (5).
  1. Establish the special tool (компрессиметр) in a spark plug aperture.
    • The special tool
      • (): 09915-64510-001
      • (): 09915-64510-002
      • (): 09915-64530
      • (D): 09915-67010
  1. Switch off coupling (to reduce initial loading by the engine) for models М/Т, and press a pedal of management of giving of fuel against the stop completely to open throttle заслонку.
  1. Start the engine with completely charged accumulator and read the maximum instrument of pressure on компрессиметре.

To measure pressure of compression, start the engine, at least, on 250 turns in a minute, with the help of completely charged accumulator.

Technical characteristics pressure of compression


Pressure of compression

The normal

1400 кПа (14.0 kg/sm2, 199.0 пси)

The limiting

1200 кПа (12.0 kg/sm2, 170.0 пси)

The maximum deviation between two cylinders

100 кПа (1.0 kg/sm2, 14.2 пси)

  1. Execute points 9 - 11 on each cylinder to read four instruments.
  1. After check insert spark plugs (2) and coils of ignition (1).
  1. Connect муфты ignition coils.
  2. Connect a cable of an accelerator (3) to a clip (4) (only for vehicles with the left wheel).
