Routine maintenance

Compression check

Pressure of compression upon all four cylinders is checked as follows.

 PERFORMANCE ORDER

  1. Warm up the engine.
  2. 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 on a range Р), both establish a lay brake and block приводные wheels.


  1. Disconnect a connector of a bunch of wires of a fuel injector.
  1. Remove knots of the coil of ignition and all spark plugs concerning a spark plug and the unit of the coil of ignition in the Head System of ignition.
  1. Establish the special tool for compression measurement in cylinders (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 компрессиметере.
    2. компрессиметре

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

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 item 5 – 7 on each cylinder to read four instruments.
  1. After check insert spark plugs and knots of the coil of ignition and reliably connect a connector of a bunch of wires of a fuel injector.
