Withdrawal PERFORMANCE ORDER | 1. Disconnect the negative battery terminal. | | 2. Loosen the nuts and bolts of the power steering pump. Turning the pump, loosen the tension of the belt drive power steering pump and air conditioning compressor. | 3. Remove the drive belt power steering pump and / or air conditioning compressor. | 4. Loosen the bolts of the generator and an adjusting bolt tension alternator drive belt. | 5. Remove the alternator mounting bolts. | 6. Remove the water pump pulley. | 7. Remove the screws and remove the ancillary drive pulley and the guide plate toothed belt from the crankshaft. | 8. Remove the screws and remove the upper and lower casings of a gear belt. | 9. Rotate the crankshaft so that the adjusting label on a pulley of a gear belt drive the crankshaft combined with the index on the engine block. | | 10. Check that the label I on a pulley of a camshaft of inlet valves combined with the index on the cylinder head cover and the label E on the pulley exhaust camshaft aligns with the index on the cylinder head cover. | A warning After combination of labels with pointers do not turn distributive and cranked shaft.
| 11. Loosen the bolt mechanism of a tension roller of a gear belt. | 12. Protect the toothed belt with a clean cloth. | 13. Remove the roller tensioner. | 14. Remove the timing belt from the engine. | A warning Note the direction of rotation of the toothed belt to be reinstalled in its original position.
|
|
Check A warning Strongly do not bend a gear belt or change its direction of rotation. Do not allow oil and lubricant to come into contact with toothed belt, as it will lead to its destruction.
PERFORMANCE ORDER | 1. Replace the timing belt, if it is contaminated with oil or lubricant. | | 2. Check the toothed belt for damage, wear, separation, cracks in the teeth and at the base of teeth, and the defects at the ends and back of the belt. In the presence of defects, replace the timing belt. | | 3. Bend the toothed belt in a circle with a diameter of 25 mm and check for cracks and bundles. | | 4. Rotate the roller mechanism of a tension of a gear belt, check for jams, smooth and easy rotation. | | 5. Check the condition of the toothed belt pulleys of distributive and cranked shaft for wear and broken teeth. If necessary, replace the pulleys. |

Setting
ENGINE A5D PERFORMANCE ORDER | 1. Install the clip mechanism of a tension of a gear belt. | A warning When replacing the timing belt is required to replace a spring mechanism of a tension of a gear belt
| | 2. Pull the roller mechanism of a tension of a gear belt to the maximum distance and fix its bolt in this position. | | 3. Check that the label on a pulley of a gear belt of a cranked shaft is combined with a pointer to a block. | | 4. Check that the label I on a pulley of a camshaft of inlet valves is aligned with the pointer on the head cover and the label E on the pulley exhaust camshaft is aligned with the pointer on the cylinder head cover. | A warning When re-installing the timing belt, install it according to earlier put labels.
| | 5. Install the timing belt on the crankshaft pulley, guide pulley, the pulley exhaust camshaft pulley inlet camshaft pulley and tensioner. | 6. Check that the timing belt does not sag in the branch between the roller mechanism of a tension pulley and the exhaust camshaft or between the camshaft pulleys. | 7. Loosen the bolt mechanism of a tension roller of a gear belt, whereby under the influence of a spring clip rotates and generate toothed belt tension. | A warning Do not spend the additional tension of a gear belt.
| 8. Tighten the bolt of the roller mechanism of a tension of a gear belt. Torque: 38-51 N ??? m | 9. Turn the clockwise crankshaft two complete revolutions and combine a label on a pulley of a gear belt of a cranked shaft with the index on the engine block. | 10. Check that the label I on a pulley of a camshaft of inlet valves and the label E on the pulley exhaust camshaft are aligned with the pointer on the cylinder head cover. | 11. If the labels are not combined with indexes, remove a gear belt and repeat the operation for installing it. | 12. Check the tension of the toothed belt. Press firmly 10 kg to the middle branch of the toothed belt between pulleys of camshafts and measure the deflection of the timing belt. Deflection: 11-13 mm | 13. Install the upper and lower casings of a gear belt and fix their bolts. The inhaling moment: 7,9-10,7 N ??? m | 14. Install guide plate and the toothed belt crankshaft pulley the ancillary drive motor and fix their bolts. The inhaling moment: 12,3-17,2 N ??? m | 15. Install the water pump pulley and fix bolts. The inhaling moment: 12,3-17,2 N ??? m | 16. Install the alternator drive belt and adjust its tension. | | 17. Install the drive belt power steering pump and air conditioning compressor and adjust its tension. | 18. Connect the cable to the negative terminal of the battery. |
