Assembly Procedure
Notice
In case the prechambers are reused, inspect the
prechambers thoroughly, if the ball pin by heat and fire is
broken, it can not be used.
1. Clean the sealing surface of the prechamber.
2. Insert the prechamber into the cylinder head at the same
time aligning the cam on the collar of the prechambers with
the slots in the cylinder head.
Notice
If the spacer rings are fitted to the prechambers, the spacer
rings should be replaced with rings of the same thickness.
Thickness of Spacer Ring 0.3, 0.6, 1.0 mm
3. Coat the threaded ring with oil and assemble the ring by
using the serration wrench.
Tightening Torque 130 Nm

Tightening Torque 0.3, 0.6, 1.0 mm
Milling of the Prechamber Sealing Surface
Notice
The prechamber sealing surface may only be remachined
once with the cylinder head fitted. It is essential to adhere
to the specified projection ‘C’ of the prechamber of 7.6 -
8.1mm.
This ensures that the required clearance exists between
prechamber and piston crown with the piston in TDC. For
this reason, spacer rings should be inserted on remachined
sealing surfaces.
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 remachining is necessary on a
prechamber sealing surface. Tools Required
601 589 00 66 00 Counter Sink
667 589 00 23 00 Height Gauge

Setting (with cylinder head installed)
1. Remove the prechamber of No. 1 cylinder.
2. Position the piston of No.1 cylinder at BTDC 10.
3. Install the measuring device into the prechamber bore and
position the dial gauge with a preload of 5mm.
Dial Gauge 001 589 53 21 00
Depth Gauge 601 589 07 21 00
4. Slowly rotate the crankshaft in the direction of engine rotation
until the large pointer on the dial gauge stops (TDC position).
Notice
The position of TDC is when the large pointer on the dial
gauge is stopped before moving back.
5. remove the reinstall the measuring device and position the
dial gauge scale at ‘0’.
6. Slowly rotate the crankshaft in the direction of engine rotation
until the dial gauge has moved back (counterclockwise) by
3.65mm.
7. Insert fixing device into the sensor bracket.
Notice
The pin on the vibration damper must engage into the slot
of the fixing device.
Fixing Device 667 589 01 21 00
8. If the pin does not engage, adjust the setting of the sensor
bracket by removing and tightening of the sensor bracket
bolts.
Tightening Torque 10 Nm
Notice
The timing mark on the damper must be positioned at ATDC
20.

The twelve-sided socket head bolts are tightened with each
stages of torque and torque angle.
It is not necessary to retighten the cylinder head bolts at
the 1000~1500km inspection or after 1000~1500km of
repairs.
Notice
The cylinder head may only be removed when the engine
has cooled down. The cylinder head is removed together
with the exhaust manifold. As the cylinder head bolts
undergo a permanent tightening. They require to be
replaced if they exceed the maximum lengthes indicated
in the table.
