amount of high melting point grease place the

two pieces of wire (A) onto the piston crown (B)

at either side of the gudgeon pin axis and 90° to

the centre line.

The two wires should just touch the cylinder bore

and care should be taken to ensure they are not

placed over any markings on the piston crown.

Figure 2.26.1 Checking Cylinder Head Clearance with Wire (an

LPW head is shown)

6. Replace the cylinder head and torque the bolts

in stages:

Stage 1 - 8.0Nm (6.0lbf ft).

Stage 2 - 48.0Nm (35.0lbf ft).

Stage 3 (LPW, LPWT and LPWS only) -

88.0Nm (65.0lbf ft).

7. Rotate the engine by hand for two complete

revolutions.

8. Remove the cylinder head and measure the

thickness of the lead; this should be 0.7-0.9mm

(0.027-0.035in).

If the clearance is not correct it can be adjusted

by changing to a different thickness of gasket.

Only one gasket must be fitted and the available

sizes are given in "2.26.2 Cylinder Head

Gaskets".

9. Replace the push rods and cylinder heads after

referring to "2.24.2 Refitting a Cylinder Head".

water Cooled gasket Part numbers

Only the 1.47mm gasket is currently offered for

spares use and these can be identified by the

blue screen printed sealing compound and the two

identification holes.

2.27 tHe vALves

The valves are pre-finished and therefore no

lapping or further processing is required and they

are sunk below the combustion surface of the head

to the figures given in "2.27.3 The Valve Seats".

Care must be taken to ensure that all valve

associated items are retained in their respective

cylinder orientation.

2.27.1 removing a valve

1. Lay the head upright on a bench and place a

suitable circular block of wood under the head of

the valve.

2. Fit the adaptor (A) onto the valve spring carrier

with the two indentations facing outwards.

3. Fit the tool (B) into the two plate indentations.

Figure 2.27.1 Valve Spring Compressor - 393155

4. Push down on the tool to compress the valve

spring until the collets can be removed.

5. Gently release the tool and remove the carrier,

valve spring, valve stem sealing ring and the

valve spring plate.

6. Turn the cylinder head over and remove the

valve.

2.27.2 Refitting a Valve

It is recommended that all valves and springs are

replaced during a major overhaul.

A valve stem sealing ring is fitted to the top of the

valve guides and it is recommended that a new

seal is fitted whenever the valves are being refitted

or renewed.

For all diesel fuelled engines new valve guides and

valve stem seals have been introduced; see "2.28

The Valve Guides" and 'Figure 2.27.3'.

If more than one valve was removed ensure they

are replaced in their original respective positions.

1. Replace the valve if it is pitted or damaged.

2. Lightly lubricate the valve stem and insert the

valve.

3. Lay the head upright on the bench and place

a circular block of wood under the head of the

valve being replaced.

4. Place the valve spring plate (B) in position.
