Examination
Pulleys, toothed belt tensioner pulley and idler pulley
1. Check the camshaft pulley, crankshaft pulley, idler pulley and idler pulley for uneven wear, cracks or damage. Replace them as needed.
2. Check the ease and smoothness of rotation of the tensioner pulley and the idle pulley, as well as the absence of extraneous noise during rotation. Replace them as needed.
3. Replace pulleys if there is any lubricant leakage.
Toothed belt
1. Check the toothed belt for oil, water or dust. Replace belt if necessary. Minor marks should be wiped off with a dry cloth or paper. Do not clean the toothed belt with solvent.
2. After repairing the engine or adjusting the belt tension, check the condition of the belt. If the following defects are present, replace the toothed belt.
- Strongly do not bend a gear belt and do not change the direction of its rotation.
- Do not allow oil and lubricant to come into contact with the toothed belt as this will cause it to break.
Description | Defect | |
1. Rigid toothed belt back | The surface has a glossy appearance. The hardness of the surface is such that the nail does not leave marks on the belt | |
2. Cracks on the reverse surface of the toothed belt | ||
3. Cracked or split toothed belt | ||
4. Heavily worn teeth | The side of the tooth is worn out, showing the fibers, cord and rubber base | |
5. Heavily worn teeth (last stage) | The side of the tooth is worn out, at the same time scuffs become visible and the thickness of the tooth is reduced | |
6. Cracks at the base of the teeth | ||
7. Missing tooth | ||
8. Strong wear on one side of the belt | A normal belt should have a flat side end, as if cut with a sharp knife | |
9. Cracks on the side of the toothed belt |
Installation
Engines 1.8 and 2.0 l
1. Install bushing and crankshaft pulley as shown. Pay attention to the direction of their installation Tightening torque: 170–180 Nm.
2. Install the camshaft pulley and secure with a bolt, tightening it to the required torque. Tightening torque: 100–120 Nm.
3. Align the alignment marks on the pulleys of the camshaft and crankshaft with the pointers, while the piston of the first cylinder should be set to TDC on the compression stroke.
4. Install the toothed belt tensioner and idler.
5. Install the toothed belt on the camshaft pulley.
After installing the toothed belt on the camshaft pulley, while pressing the pulley of the timing belt tensioner to the water pump, make sure that it does not sag on the tension side.
6. Turn the engine crankshaft clockwise one revolution and align the mark on the crankshaft timing belt pulley with the pointer on the engine block. Check that the mark on the camshaft pulley is aligned with the pointer on the cylinder head cover.
Do not turn the engine crankshaft counterclockwise. The moment of an inhaling of bolts of fastening of the mechanism of a tension and a directing roller: 43–55 Н·м.
7. Recheck the toothed belt tension. When pressing on the tensioned branch of the toothed belt with a force of 20 N, the belt should bend by approximately 4–6 mm.
8. Establish casings of a gear belt. Tightening torque: 8–10 Nm.
9. Install the crankshaft pulley. Tightening torque: 140–150 Nm.
10. Install the water pump pulley.
11. Install the V-ribbed belt and adjust its tension.
1.6L engines
1. Install bushing and crankshaft pulley as shown. Pay attention to the direction of their installation Tightening torque: 140–150 Nm.
2. Install the camshaft pulley and secure with a bolt, tightening it to the required torque. Tightening torque: 80–100 Nm.
3. Install the guide roller and secure with the bolt, tightening it to the required torque. Tightening torque: 43–55 Nm.
4. Align the alignment marks on the pulleys of the camshaft and crankshaft with the pointers, while the piston of the first cylinder should be set to TDC on the compression stroke.
5. When installing the toothed belt tensioner, install the tensioner, spring and spacer first. Temporarily tighten the bolts. Then, temporarily compress the tensioner by inserting the bolt into the elongated hole. Install the rear end of the flat spring against the front cover as shown.
6. Lock the tensioner attached to the water pump.
7. Install the timing belt on the crankshaft pulley.
8. Install the toothed belt on the camshaft pulley, making sure that it does not sag on the tension side.
9. Tighten the tensioner bolts.
10. Turn the engine crankshaft clockwise one revolution and align the mark on the crankshaft timing belt pulley with the pointer on the engine block. Check that the mark on the camshaft pulley is aligned with the pointer on the cylinder head cover. Tightening torque of the tensioner mounting bolt: 20–27 Nm
11. Recheck the toothed belt tension. When pressing on the tensioned branch of the toothed belt with a force of 49 N, the toothed belt should bend to the center of the head of the tensioner fastening bolt.
12. Establish casings of a gear belt. Tightening torque: 8–10 Nm.
13. Install the crankshaft pulley. Make sure the crankshaft pin fits into the pulley hole. Tightening torque: 140–150 Nm.
14. Install the fan drive belt and adjust its tension.
15. Install the water pump pulley.
16. Install the V-ribbed belt and adjust its tension.
