Caution: The arrows on the timing belts must point in the direction of engine rotation (i.e. clockwise).
When putting on toothed belts, you need to start with the crankshaft sprockets and put the belts on further in a counterclockwise direction, i.e. in the following sequence: crankshaft sprocket, camshaft or fuel injection pump sprocket, tension sprocket. In this case, the weakened part of the toothed belt will fall on the spring-loaded tension roller.
Caution: After installing the timing belt, the timing belt sprocket bolts must be positioned in the middle of their longitudinal holes.
Loosen the mounting bolt (A) of the camshaft drive toothed belt tension roller so that the tensioner rests against the belt under the action of the spring.
Tighten bolt (A) to 50 Nm.
Tighten the camshaft sprocket mounting bolts (B) to 10 Nm.
Loosen the mounting bolt (A) for the injection pump drive toothed belt tension roller so that the belt tensioner rests against the toothed belt under the action of the spring.
Tighten bolt (A) to 45 Nm.
Tighten the fuel injection pump sprocket mounting bolts (B) to a torque of 25 Nm.
Remove all three mounting pins.
Turn the crankshaft clockwise until the fuel injection pump sprocket has made one full revolution. Finally, turn the crankshaft to the TDC position and insert the three dowel pins.
Loosen the bolts of the camshaft sprockets and the fuel injection pump.
Loosen the bolt (A) of the injection pump toothed belt tensioner by a quarter of a turn so that the belt tensioner is freely pressed against the toothed belt.
Tighten the bolt (A) of the fuel injection pump drive toothed belt tensioner to a torque of 45 Nm. Tighten the bolts (B) of the fuel injection pump sprocket to a torque of 25 Nm.
Loosen the camshaft timing belt tensioner bolt (C) by a quarter of a turn so that the tensioner is pressed freely against the belt.
Tighten the camshaft timing belt tensioner bolt (C) to 50 Nm. Tighten the camshaft sprocket bolts (D) to 10 Nm.
Check again that the dowel pins are inserted correctly and that the crankshaft rests against the dowel pin for TDC. Finally, remove all the adjusting pins.
Screw the plug bolt into the cylinder block and tighten it to a torque of 25 Nm.
Install the upper and lower timing belt covers.
Install the poly V-belt.
Install the right engine support and tighten the new nuts. Tighten the nuts on the engine side to 120 Nm, on the body - 70 Nm.
