Withdrawal
1. Loosen the water pump pulley bolt.
2. Loosen the alternator mounting bracket.
3. Remove the water pump pulley and belt.
4. Remove the crankshaft pulley.
5. Remove a cover of a gear belt.
6. Move the toothed belt tensioner pulley to the water pump and temporarily secure it.
7. Remove the toothed belt from the camshaft sprocket.
8. Remove the camshaft sprocket.
9. Remove a gear belt.
Note. If the toothed belt has already been running, draw an arrow showing the direction of its movement so that after installation it moves in the same direction.
10. Remove the crankshaft sprocket mounting bolts, remove the flange and sprocket.
11. Remove the toothed belt tensioner.
Examination
1. Check the camshaft and crankshaft gears and tensioner for wear, cracks and damage. Replace if necessary.
2. Check the ease and smoothness of rotation of the tensioner, as well as the play and noise of operation. Replace if necessary.
3. Check the presence of oil and dust on the belt, defects, if necessary, replace the belt. Light deposits can be wiped off with a dry cloth or paper. Do not use solvent to clean the belt.
4. When overhauling the engine or adjusting the belt tension, check its condition more carefully. If there are defects, the belt should be replaced with a new one.
Installation
1. Install the flange and crankshaft sprocket as shown. Pay special attention to the conditions of their fastening.
Tightening torque: Crankshaft pulley bolt - 140-150 Nm.
2. Install the camshaft sprocket and tighten the bolt to the required torque.
Tightening torque: Camshaft sprocket bolt - 80-100 Nm
3. Align the marks on the crankshaft sprocket and camshaft sprocket. The piston of cylinder #1 should be at top dead center on the compression stroke.
4. Install the toothed belt tensioner; First of all, the tensioner, spring and washer are attached. Temporarily tighten the bolts. Then temporarily tighten the bolts and washer from the elongated hole side of the tensioner.
Install the lower end of the spring against the front cover as shown in the illustration.
5. Attach the tensioner towards the water pump.
6. Install the timing belt on the crankshaft sprocket.
7. Install the toothed belt on the camshaft sprocket. When installing the timing belt on the camshaft sprocket, make sure the tension side is tight. Then rotate the camshaft sprocket in the opposite direction with the tension side tightened. All alignment marks must be on the same line.
8. Loosen bolts 1 and 2 fastenings exactly in the specified order. This will bring the spring tensioner closer to the timing belt. Check the belt to make sure it has not lost its position.
9. Tighten, bolts 2 and 1 of fastening of a tensioner in the specified order. If bolt 1 is tightened first, the tensioner may move with the bolt, which may cause the belt to be over tightened.
10. Turn the crankshaft once clockwise and set the mark 'on the crankshaft gear at top dead center.
Warning. Do not turn the crankshaft in a counterclockwise direction.
11. Loosen the bolts 1 and 2 of the tensioner mounting in the order shown.
12. Retighten bolts 2 and 1 of fastening of a tensioner in the specified order the demanded moment of an inhaling.
Tightening torque: Tensioner mounting bolt - 20-27 Nm (200-270 kg/cm)
13. Recheck belt tension. Then push the tensioner and the belt from the tensioner side in a horizontal direction with medium force (approximately 49 N), approximately to the tips of the belt teeth.
The end of the belt tooth must be half the radius of the tensioner bolt head from the center of the bolt head (see operation above in this chapter "Belt tension adjustment").
14. Establish a cover of a gear belt.
Cover bolt tightening torque - 10-12 Nm
15. Install the crankshaft pulley. Make sure the crankshaft sprocket pin is recessed into the hole in the pulley.
Pulley bolt tightening torque - 140-150 Nm
16. Install fan belt and adjust belt tension.
17. Install the water pump pulley.
18. Install the V-belt and adjust its tension.
