Compression Pressure Measurement
Notice
Ensure that no gear is engaged and that the vehicle
is protected from rolling.
1. Run the engine to be the coolant temperature 80_C.
2. Remove the fuel injection nozzle.
Socket Wrench Insert 001 589 65 09 00
3. Install the test adapter (1) and connect the flexible
connector (2) to the compression pressure recorder.
Compression Pressure Recorder 001 589 76 21 00
4. Disconnect the vacuum line from the stop unit and
connect the hand vacuum pump to the stop unit.
5. Pump the hand vacuum pump and make the fuel in-
jection pump in stop position.
Operating PressureApprox. 500bar
Hand Vacuum Pump 001 589 73 21 00
6. Using a starter motor, crank the engine 8 revolu-
tions.
7. Measure the remaining cylinder compression pres-
sure in the same manner and compare it with ser-
vice data.
Notice
If out of standard, do cylinder pressure leakage test.
8. Remove the compression pressure recorder.
9. Install the fuel injection nozzle.

21. Remove the fuel lines from the fuel filter and cover
the filter with plug.
22. Disconnect the brake booster hose from vacuum
pump.
23. Disconnect the other vacuum lines.
24. Disconnect the ground cable.
25. Disconnect the generator wires.
26. Disconnect the starter motor wires and remove the
starter motor.

8. Remeasure size ’X’ and compare it with the first
measurement and determine the thickness of
spacer ring.
Ex
Size before machining25.7 mm
Size after machining25.5 mm
The spacer ring should be selected so that it is at
least 0.1mm and not more than 0.3mm thicker than
the measured on the sealing surface. In this exam-
ple, the necessary thickness of spacer ring should
be within 0.3 ~ 0.5mm and the thickness of spacer
ring to be installed is 0.3mm.
9. Remove the countersink tool and clean the chips.
Notice
If the sealing surface is not completely flat, rema-
chine the sealing surface.
10. Remove rag from the prechamber bore and crank
the engine with starter motor to threw out any chips
which may have got into the combustion chamber.
11. Insert the proper spacer ring into the prechamber
sealing surface.
12. Punch a mark on the cylinder head above the pre-
chamber sealing surface which has been machined.
13. Install the prechambers.
Notice
If the cylinder head is removed, the projection ’C’ is
measured in place of size ’X’ and the appropriate
size of spacer ring selected.
Normal Projection (c)7.6 -- 8.1mm
