1) onto the plastic plug 1 (Fig. 52) of the special tool on the protruding portion of the valve sleeve; 2) thoroughly lubricate the cap 2 and put it on a plastic sleeve; 3) to install the tool on the cap 3 and gently pressing the latter in the direction of the valve sleeve. Please note that the caps when installing such an instrument could be damaged, resulting in oil consumption will be significant; - If the wire lapping of valves, they must be sure to enter in the appropriate seat, since all the valves ground in only their saddles; - Installed on the cylinder head valve springs;

- Set the upper spring. To compress the springs to use a stripper valve in accordance with Fig. 34. If the end of the rod protrudes from the top plate, then insert the needle-nose pliers are both using the biscuit into the groove of the valve rod and slowly remove the valve remover; - Turn to hit a plastic hammer on the upper end of the valve stem. Incorrectly installed valves crumbs fall out while outside. As a precaution, close the ends of the springs rag items scattered in different directions; - Install the camshaft and the control camshaft pulley as described in Section. 2.7.3; - To take in the arm cuff camshaft and determine which side is the spring. Set the cuff so that its spring facing the inner cavity housing lightly lubricated sealing lips and the working surface of the shaft; Using a suitable mandrel, gently blows cuff set in the cylinder head; - Set the cylinder head as described in the next section; - Installed on the rear cylinder head cover and tighten the two screws 7 and 8 (see. Fig. 25) corresponding torque;

Details on the front side of the engine: 1 - the top casing of a gear belt; 2 - a gear belt; 3 - bolts 20 Nm; 4 - a protective casing of a gear belt pulley for the pump; 5 - bolt 80 Nm; 6 - a gear pulley of a camshaft; 7, 8 - bolts 10 Nm; 9 - a casing of a gear belt (inside); 10 - O-ring; 11 - the water pump; 12 - belt tensioning device; 13 - nut 20 Nm; 14 - mounting bracket; 15 - a gear pulley of a cranked shaft; 16 - bolt 40 Nm + 90 ?�; 17 - the crankshaft pulley; 18 - bolt 20 Nm; 19 - ribbed belt; 20 - bolt 90 Nm + 120 ?�; 21 - the bottom casing of a gear belt
|
- Install the shaft camshaft sprocket (not to forget the key) and screw the bolt and washer. Block pulley (for example, the old toothed belt or by inserting a mandrel into one of the holes in the camshaft pulley and using it as a prop) Tighten the bolts to 80 Nm; - Set on the cylinder head intake and exhaust manifolds (use a new gasket), if they were removed. Replace the cylinder head all the disconnected elements.
