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.

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.
