Measurement of Mating Surfac
1. Measure the height (H) of the cylinder head(refer to
Service data standard).
2. Check the mating surface of the cylinder head.
3. Mill the sharp edge of the combustion chamber.
4. Re-- measure the height (H) of the cylinder head.
5. Seal the intake and exhaust valves.
6. Measure the dimension (T) between the camshaft
bearing and the valve system(refer to Service data
standard).
7. Mill the cylinder head valve seat(refer to Service data
standard).

Milling of the Prechamber Sealing Surface
Notice
The prechamber sealing surface may only be rema-
chined once with the cylinder head fitted. It is essen-
tial to adhere to the specified projection ’C’ of the
prechamber of 7.6 -- 8.1mm.
This ensures that the required clearance exists be-
tween prechamber and piston crown with the piston
in TDC. For this reason, spacer rings should be in-
serted on remachined sealing surfaces.
Thickness of spacers0.3, 0.6, 1.0 mm
If a spacer ring is already fitted, or a marking is
made on the cylinder head, the cylinder head must
be removed and size ’C’ measured if further rema-
chining is necessary on a prechamber sealing sur-
face.

1. Remove the injection nozzle.
2. Remove the prechamber.
3. Cover the prechamber bore to avoid any chips drop-
ping into the combustion chamber.
4. Remove the protective sleeve from the countersink
and rotate the countersink into the prechamber bore
to be machined as far as the stop.
Counter Sink 601 589 00 66 00
5. Maintain size ’X’ from the top edge of mandrel to the
top edge of the sleeve with the gauge.
Height Gauge 667 589 00 23 00
6. Measure the ’X’ by using a vernier caliper.
7. Mount the turning tool onto the countersink tool and
rotate to the right approx. 5 revolutions by applying
slight pressure.

Notice
If the height is less than 142.5mm, replace the cylin-
der head.
2. Insert the valve (1) and measure valve arrears ’a’.
Valve Arrears ’a’0.1 -- 0.7 mm
Notice
If out of standard, machine the valve seat.
3. Install the prechamber and measure protrusion ’C’.
