Assembly ProcedureNotice 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

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. Forthis reason, spacer rings should be inserted on remachinedsealing 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.

1B3-36 OM600 ENGINE MECHANICAL 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 andposition 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) by3.65mm.
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 bracketbolts.
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 bereplaced if they exceed the maximum lengthes indicatedin the table.
