Note. The timing chain can be replaced without dismantling the engine. Using the tools listed below, the new chain can be connected to the old chain, passed around the sprockets and minted.
Attention! If assembled incorrectly, the valves may collide with the piston crowns!
General information

- Observe the tightening torques of the fasteners stipulated by the regulations;
- With the appropriate configuration, do not forget to mark the installation position of the CKP sensor before removing it;
- Do not turn the crankshaft using the camshaft sprockets, as well as other timing sprockets;
- Do not turn the crankshaft and camshafts with the timing chain removed;
- After installing the valve timing, do not forget to check the settings of the injection pump.
Servicing Timing Drive Components
1. Disconnect the negative cable from the battery.
2. Remove all glow plugs to make cranking easier.
3. Bring the crankshaft to the TDC position of the piston of the first cylinder (1).
4. Insert stopper rod into intake camshaft (2).
5. Make sure the camshaft sprocket sprocket 1.5mm holes are properly aligned (3).
Note. Camshaft sprockets are fastened with disposable bolts (4), that must be replaced without fail. 6. Before proceeding with the repair procedures, remove the tensioner assembly (5).
7. When removing / installing the injection pump, the crankshaft should be brought to the position 14±0.5°after the TDC of the piston of the first cylinder (6).
8. Before removing the bolt (7) Type A injection pump install sprocket centering tool No. 601589051400.
Note. The injection pump sprocket bolt has a left-hand thread. After removing the injection pump, install the locking tool (8).
9. Lower the pump with the plunger down into a container with impellent oil and squeeze the plunger 7-10 times. After filling the high-pressure fuel pump with oil, check the plunger for smooth movement and the adequacy of its compression resistance.
10. At installation of an asterisk of a camshaft track correctness of an arrangement of a directing pin.
11. Before installing, fill the tensioner by lowering it with the plunger down into a container with SAE 10 engine oil and depressing the plunger 7-10 times. Check the smoothness of the plunger and the adequacy of the resistance to its compression.
12. Having completed the necessary reconditioning, install the tensioner in its regular place.
