Removal
1. Remove the oil pan (see the relevant chapter).
2. Unscrew the crankshaft position sensor 1 together with the O-ring from the cylinder block (see illustration).
3. Install the stop pin 2 KM-929 into the hole of the crankshaft position sensor and lock the crankshaft (see illustration). If necessary, turn the crankshaft slightly in the direction of engine rotation using the belt pulley mounting bolt. In this position of the crankshaft, marks 3 should be aligned opposite each other.
4. Remove cover 1 from the torsional vibration damping unit (see illustration).
5. Install pin 3 KM-979 into the block, unscrew the chain tensioner by hand, and insert stop pin 2 KM-978 into its hole (see illustration).
6. Unscrew bolt 5 securing sprocket 4, remove the sprocket from the damper shaft and remove the chain from it (see illustration 15.5).
