3.4 CHECKING CYLINDER HEAD BOLTS

Cylinder head bolts can be re-used provided they 
satisfy a number of conditions. If a cylinder head 
bolt does not meet one or more of these 
conditions, new cylinder head bolts must be 
used.

1.

Check cylinder head bolts for damaged 
screw threads, corroded surfaces and 
thinning as a result of overstretching.

2.

Check the dimensions of visible pitting on the 
cylinder head bolt, see "Technical data".

3.

Check the cylinder head bolt for visible 
corrosion or pitting immediately under the 
bolt head and directly above the start of the 
screw thread, see "Technical data".

for this purpose. Place the bolt head against 
the abutting surface.

5.

The end of the bolt must not touch the gauge.

3.5 INSPECTION, FLYWHEEL

If cracks are visible on the flywheel, on the 
contact surface of the clutch plate, it must be 
replaced.

Checking flywheel run-out
1.

Clean the flywheel.

2.

Place a metal strip on the edge of the 
flywheel housing to fit a dial gauge.

3.

Place the dial gauge on the metal strip.

4.

Place the stylus of the dial gauge as close as 
possible to the outer edge of the flywheel.

5.

Set the dial gauge to "0".

6.

Use an open-end spanner on the fan shaft to 
crank the engine through 360

|, and measure 

the maximum dial gauge reading. Compare 
the reading with the technical data. See 
"Technical data".

3.6 INSPECTION, ENGINE OIL SUMP PRESSURE

}

Be careful when working on an 
engine at operating temperature.

The oil sump pressure is measured to quickly 
check the cylinder seals. The readings obtained 
are an indication of the leakage from all cylinders.

1.

Bring the engine up to operating 
temperature.

2.

Turn off the engine and fit the special tool  
(DAF no. 1240080) (1) to the crankcase 
breather hose.

3.

Fit the special tool with a water pressure 
gauge  (DAF no. 1240081) (2) using a hose 
and start the engine.

4.

Using the water pressure gauge, measure 
the oil sump pressure at idling speed and 
compare the measured reading with the 
technical data. See "Technical data".
