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".

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

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".
