4.1.2.7 CHECKING THE COMPRESSION PRESSURE

- Remove the injection nozzle.

- Check the valve clearance.

- Insert and fasten connector 100110 along with the special seal.

- Connect a compressometer and crank the engine with the starter.

Specified pressure 30 - 38 bar

Max. difference in pressure 4 bar

NOTE: The measured compression pressure depends on the RPM of the starter when the

measurement is carried out and on the altitude of the place the engine is operated in.

For this reason it is not possible to define exact limits. The compression pressure check is

only recommended as a means of comparing all cylinders in relation to each other. If the

difference in pressure exceeds 15 %, dismantle the appropriate cylinder unit and determine

the cause.
