Remove the damper pulley of the fuel pump (Fig. 3.4.26). 2 nut fastening of a pulley of the fuel pump should not be unscrewed, because otherwise the changed fuel injection timing.
A WARNING Chalk, markers or paint mark the direction of rotation of the toothed belt. After setting the belt rotates in the opposite direction, which may result in its destruction. |

|
Remove the eight screws and remove the damper with the crankshaft pulley (Fig. 3.4.27).
A WARNING To remove the damper with the crankshaft pulley is not required to unscrew the central pulley bolt. |

Allen wrench to turn the 8 mm toothed belt tensioner pulley clockwise and fix the pin diameter of 2 mm (Fig. 3.4.30).
| Fig. 3.4.31. Use puller Kukko 204-1 (1) for the removal of a pulley of a gear belt from a camshaft
|
Using puller Kukko 204-1 (Fig. 3.4.31), remove both camshaft pulley landing cones camshafts. This stripper should rest on the bolts camshaft pulleys. Camshaft pulley must rotate freely on the mounting cones, but do not have excessive play. Remove the bolt and remove the toothed belt pulley with the left cylinder head. Remove the timing belt.
Setting Check that the camshaft has been fixed retainers 3458, and was the crankshaft at TDC of the first cylinder on the compression stroke. Camshaft pulleys must turn freely. Install the timing belt can be as cold and the warm engine. Between the pulley and the crankshaft of grease. First, insert the timing belt on the crankshaft pulley, then on the tensioner pulley, idler pulley, water pump pulley and the pulley of the right camshaft. After that, put on a gear belt on a pulley of a camshaft of the left, install the pulley on the camshaft and secure with the bolt. Allen wrench to turn the 8 mm toothed belt tensioner pulley clockwise to a torque of 15 Nm, remove the locking pin diameter of 2 mm (see. Fig. 3.4.30), and release the key. Using a special device 3036 (see. Fig. 3.4.29), lock the camshaft pulley against rotation and alternately tighten the bolts camshaft pulley. Tighten them to a torque of 80 Nm. Install the cooling fan bracket and secure it with screws (see. Fig. 3.4.28).

|
Install the drive pulley of the fuel pump so that the bolts are located in the middle of the elongated holes of the pulley, and tighten the screws so that you can turn the pulley of the fuel pump on the camshaft pulley. Install the timing belt fuel pump. Adjust the tension of the toothed belt of the fuel pump, for which an Allen key, turn the tensioner anti-clockwise before combination of labels 1 (Fig. 3.4.33), and a second wrench to tighten the nut to 36 Nm. Tighten the camshaft pulley to 20 Nm. Remove clamps 3458 camshafts. Remove the pin 3359, fixed pulley of the fuel pump. Remove the set screw 3242, fixed crankshaft. Remove the set screw clamps 3242 and 3458, a cranked shaft on two complete revolutions, set it to the TDC of the third cylinder on the compression stroke and check for correct installation of the crankshaft and camshafts. To check the position of the crankshaft remove the plug from the cylinder block, and instead tighten the set screw 3242 (see. Fig. 3.4.23). To check the position of the camshaft set tabs 3458 camshafts. If the set screw 3242 and 3458 locks into place, then, crankshaft and camshafts are installed correctly. Install the damper pulley of the fuel pump and fix its bolts, having tightened their moment of 20 Nm.

|
Set the damper on the crankshaft pulley, making sure that the label (Fig. 3.4.34) was combined with a label on a pulley of a gear belt, and tighten the bolts damper torque 25 Nm. On the left cylinder head, set the vacuum pump. Install poly V-belt. Further installation is carried out in reverse order of removal.
