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.

Leakage Test
1. Run the engine to be the coolant temperature 80_C.
2. Remove the fuel injection nozzle.
3. Open the coolant subtank cap.
4. Check the coolant level and replenish if necessary.
5. Open the oil filler cap.
6. Remove the air cleaner cover and element.
7. Position the piston at TDC.
8. Install the connector (1) and connection piece (2).
9. Calibrate the tester and connect the connection
hose (3)
10. Pressurize with compressed air and compare the
pressure changes with permissible pressure leak-
age.
11. If permissible pressure leakage is out of standard,
check followings :
-- Intake and exhaust lines.
-- Sounds in oil filler area.
-- Air bubbles in radiator coolant.
12. Do pressure leakage test for the remaining cylinders
according to the firing order.
DOM 662LA Engine : 1-- 2-- 4-- 5-- 3
DOM 661LA Engine : 1-- 3-- 4-- 2
13. Remove the tester.
14. Close the coolant pressure cap and oil filler cap.
15. Install the air cleaner element and cover.
16. Install the fuel injection nozzle.

24. Insert the new connecting rod bearing shells into the
connecting rod and connecting rod bearing cap and
tighten the 12--sided stretch bolts (11).
Tightening Torque40 N∙m (30 lb-ft) + 90_
25. Measure inner diameter of connecting rod bearing.
26. Measure connecting rod bearing journal diameter
(K).
Notice
Refer to measurement of the crankshaft bearing
journal diameter.
27. Measure the radial clearance (L) of the connecting
rod bearing.
Example) Measured value ’J’ = 47.700mm
Measured value ’K’ = 47.653mm
——————————————
Clearance ’L’ = 0.047mm
Radial Clearance ’L’0.026 -- 0.068mm
Notice
If the clearance is out of standard, adjust the radial
clearance of connecting rod bearing by replacing the
connecting rod bearing shells.
28. Remove the connecting rod bearing cap.
29. Install the piston.
30. Rotate the crankshaft by hand and check whether it
rotates smoothly.
31. If the bearings are damaged,
-- replace the oil presser relief valve.
-- clean the oil pump and oil filter housing carefully
and replace the hose if necessary.
Notice
After assembling the engine, check the camshaft
timing, adjust the start of fuel injection and check the
TDC sensor bracket setting.
32. Fill oil and run the engine and then check the oil
pressure and oil level.
Notice
Install the original oil filter element and then change
the engine oil and oil filter element after 1,000 --
1,500km.

Caution: Disconnect the negative battery cable before removing or installing any electrical unit or when a
tool or equipment could easily come in contact with exposed electrical terminals. Disconnecting this cable
will help prevent personal injury and damage to the vehicle. The ignition must also be in LOCK unless other -
wise noted.

5. Opening pressure test :
Open the valve (3) and slowly operate the hand le-
ver at tester (approx. 1 stroke / second) and mea-
sure opening pressure.
New Nozzle115 -- 125bar
Used NozzleMin. 100bar
Difference Between NozzlesMax. 5bar
Notice
If out of standard, repair the injection nozzle.
6. Leak test
Slowly operate the hand lever at the tester until get a
pressure of approx. 90bar. Maintain this pressure
for more than 20 seconds and within this period no
drop of fuel should build up at the nozzle tip.
