3.3.7. Gas-distributing belt

GENERAL INFORMATION

Tools for adjustment of a gas-distributing belt

1. KM-800-20

2. KM-800-1

3. KM-800-30

4. KM-800-10

5. KM-800-2

The following special tools will be necessary for adjustment of a gas-distributing belt for you: tools for blocking of asterisks of camshafts (KM-800-1 and KM-800-2), the tool for blocking of an asterisk of a cranked shaft (KM 800-10), a wedge for a gas-distributing belt (KM-800-30) and the tool for synchronization of asterisks of camshafts (KM-800-20).

Removal

PERFORMANCE ORDER
1. Disconnect a wire of the minus plug of the accumulator and establish the N1 piston in VMT.
2. Remove a pulley of a cranked shaft.
3. Check, whether sinkhronizatsionny labels are correctly combined.
4. Establish tool KM-800-10 on an asterisk of a cranked shaft and stop a shaft.
5. Stop camshafts, tool KM-800-1 (marking 1 and 2, the red handle) tool KM-800-2 (marking 3 and 4, the green handle) for shaft of the left head is intended for shaft of the right head of cylinders, and. Clamp the tool lever on a flange of the water pump.
6. Establish the tool for blocking of asterisks of camshafts (drawing at the left). Labels of TORAHS should be directed up (drawing on the right).
7. Weaken a nut of a pulley of a natyazhitel of a gas-distributing belt.
8. Turn a pulley of a natyazhitel clockwise against the stop and tighten a nut.
9. Weaken bolts top (drawing at the left) and bottom (drawing on the right) directing pulleys of a gas-distributing belt.
10. Remove a gas-distributing belt. If you did not use special tools before removing a belt, turn a cranked shaft approximately on 60 ° back. Thus, the probability of contact of valves with pistons decreases.
11. Carefully examine a belt on existence of wear and damages, if necessary replace it.

Prevention

There are two types of belts and two types of natyazhitel which are established on described engines. Depending on type of a natyazhitel the belt type depends also. The modified natyazhitel are established on model of engines of 1997 and later years of release and have marking Е on a pulley. Usual natyazhitel are established on the models of the engines which have been let out till 1997 and have marking of D. If you had difficulties with definition such as a natyazhitel, address to the expert.


PERFORMANCE ORDER
1. Carefully clean asterisks of shaft and pulleys.
2. Combine sinkhronizatsionny labels of asterisks of camshafts of the right head of cylinders (1 and 2) (drawing at the left) and left (drawing on the right) with cuts in a back cover of a gas-distributing belt and combine them anew if you turned a cranked shaft on 60 °.
3. Combine a label of an asterisk of a cranked shaft with a cut in a casing of the oil pump (are specified by shooters).
4. Put on a belt asterisks. Shooters on a belt should be turned in the direction of rotation of a belt, and the double line on a belt should coincide from a sinkhronizatsionny well-aimed asterisk of a cranked shaft.
5. Stop a gas-distributing belt by means of a wedge.
6. In engines equipped with a usual natyazhitel, the belt is necessary for dressing at first on the bottom directing pulley and on asterisks of camshafts of the left head of cylinders. The label (it is specified by an arrow) on an arm of a pulley of a natyazhitel will help to define type of a natyazhitel.
7. In engines equipped with the modified natyazhitel, the belt is necessary for putting on at first a pulley of a natyazhitel.
8. Then the belt is necessary for putting on asterisks of camshafts of the right head of cylinders.
9. Pass a belt over the bottom directing pulley.
10. Weaken a bolt of the bottom directing pulley. Turn a pulley counter-clockwise to pull the left part of a belt. Check, that sinkhronizatsionny labels were still combined.
11. Tighten a pulley bolt.
12. Weaken a bolt of the top directing pulley. Turn a pulley counter-clockwise to pull the top part of a belt. Check, that sinkhronizatsionny labels were still combined. Tighten a pulley bolt.
13. Weaken a nut of a pulley of a natyazhitel and turn the pulley lever counter-clockwise so that the distance between a plate and an emphasis made 0,5–1,5 mm (it is specified by an arrow). Tighten a nut.
14. Remove all blocking tools and turn a cranked shaft on two complete revolutions.
15. Check, that sinkhronizatsionny labels were still combined.
16. Weaken a nut of a natyazhitel and establish the lever of a natyazhitel as is shown in drawing (see fig. Adjustment of a pulley of a natyazhitel). The label (And) should be higher on 3–4 mm than an emphasis label (In). Tighten a nut.
17. Turn a cranked shaft on two complete revolutions. Check, that sinkhronizatsionny labels were still combined. If necessary carry out adjustment.
