2. Turn the crankshaft to position the each cylinder piston at
TDC.
5. Install the engine lock to the ring gear to prevent the
crankshaft from rotating.
6. Blow up with compressed air.Notice
lRemove the valve spring only at TDC.
lAlways rotate the crankshaft by holding the chain to
prevent from timing chain damage and tangling, and for
smooth rotation.
3. Remove the valve tappet (1) using the magnetic finger.
4. Install the leakage tester connecting hose to the spark plug

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.
