Removal of a damper of the engine
Removal of fastening of a back casing of a gear belt
|
|
Unscrew fastening (1). Weaken a nut (4) tension belts. |
Weakening of a tension of a gear belt
|
|
Turn a tension roller as it is possible further a screw-driver (1) to the right and tighten a nut (2) tension rollers. |
Suspension bracket installation
|
|
Establish an engine mount, having tightened (And) with effort of 115 N of m and a nut (In) with effort of 90 N of m. |
Wear of a gear belt
Installation of phases of a gazoraspredeleniye usually should be made after repair work at which the gear belt acted in film or the engine understood. At check of installation of phases of a gazoraspredeleniye it is necessary to carry out all steps except replacement of a gear belt.
Removal
| PERFORMANCE ORDER |
| 1. Disconnect minus a weight cable from the accumulator. |
Prevention
Contents of electronic memories, for example memory of defects of the engine or a radio tape recorder code are thus erased. Before shutdown of the accumulator it is necessary to read subsection 2.11.
|
| 2. Lift the car and remove the right forward wheel. |
| 3. Remove the bottom casing of the engine in the right wheel niche. |
| 4. Remove maple a belt. |
| 5. Block the engine. For blocking of the engine include the 5th transfer and let the assistant will press a brake pedal. Unscrew bolts of fastening of a belt pulley of a cranked shaft. |
|
6. Remove a pulley of a cranked shaft. |
| 7. Remove glow plugs. |
| 8. For a pro-collar of a cranked shaft of the engine tighten the hand brake and establish a transmission in neutral situation. With the help a vorotka and heads turn a cranked shaft from the right wheel niche. |
|
Prevention
At all do not turn a cranked shaft for a camshaft wheel through zubchatoremenny transfer.
|
|
9. Release a bolt of a tension roller and wring out a tension roller a screw-driver from a gear belt before weakening of a tension of a gear belt. Again tighten a bolt of a tension roller. |
| 10. Remove the right and left casing of a gear belt. |
| 11. Remove a gear belt. After that cogwheels do not turn. |
Prevention
Before removal once again check, whether the label on a wheel raspredelitelno coincides with edge of a head of cylinders in bulk, if necessary modify.
If it is necessary to turn a camshaft at the removed gear belt, any piston should not be in VMT. Otherwise there can be serious damages of pistons and valves.
|
| 12. If it is necessary to turn a camshaft, establish in advance all pistons on a half of their course. For this purpose put with chalk from above on a wheel of a cranked shaft a label. |
|
13. Before drawing of a label establish the 1st cylinder in situation VMT. For this purpose turn a cranked shaft before coincidence of a label (1) on a cogwheel of a camshaft (2) with a label on a face-to-face payment. Then turn a wheel of a cranked shaft on 1/4 turns (90 °) to the left or to the right. The label should be turned now to the left or to the right. |
|
Installation
Prevention
Gear belt do not bend and do not turn off. Surely replace the polluted, damaged or worn-out belts. Check uniformity and ease of a course of a tension roller.
| PERFORMANCE ORDER |
| 1. Check wear of a belt. |
| 2. Impose a gear belt. When imposing an old belt impose according to the put arrow in the rotation direction. |
Prevention
Be convinced that the belt well covers rollers and does not sag.
|
|
Tension
| PERFORMANCE ORDER |
| 1. Weaken a bolt of a tension roller so that the roller could move to a gear belt under effort of a spring. |
| 2. Turn a cranked shaft on two turns clockwise before coincidence of labels raspredelitelno in bulk and a face-to-face payment. Be once again convinced that all labels coincide. |
| 3. Tighten a bolt of a tension roller with effort of 45 N of m. |
| 4. Turn a cranked shaft on two turns in the direction of rotation of the engine and once again check adjustment. |
|
5. The belt piece between rollers of the water pump and a camshaft should cave in on 10,5–12,0 mm from effort in 10 kg (strong pressing by a finger) if it not so, release a bolt of a tension roller and once again pull a belt. |
| 6. Establish and fix with effort of 10 N of m the right and left casings of a gear belt. |
| 7. Put and fix the engine shock-absorber. |
| 8. Put a pulley of a cranked shaft with a washer and tighten fastening bolts with effort of 30 N of m. |
