Notice
lThe TDC sensor bracket must be adjusted in case of
followings.
lWhen replacing the TDC sensor bracket.
lWhen replacing the crankshaft, the hub or the vibration
damper.
lWhen replacing or installing the timing case cover.
lAfter engine overhauling.
*If the cylinder head is removed, the measuring pin of the
dial gauge can be positioned on the piston crown.
This is done by placing the magnetic dial holder on the
mating surface of the crankcase.

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.
