GENERAL INFORMATION

For check the tsiferblatny indicator with a nozzle for a vvinchivaniye in the pump is used.

The engine at check should be cooled, the temperature should be no more than +20 ° Page.

PERFORMANCE ORDER
1. Disconnect a cable of weight of the battery.

Prevention

Data from memory of malfunctions and protective code of a radio receiver are thus erased.


2. Unscrew the bottom guard of the engine.
3. Remove an inlet collector.
4. On cars with the conditioner remove the fan with the vyazkostny coupling.
5. Unscrew a bolt (1).
6. Screw in to the place of the unscrewed bolt a nozzle (1) (OPEL KM-226-A) and the indicator (2) (KM-571-V) and drown a plunzher a little.
7. Turn a cranked shaft clockwise in position VMT of the 1st cylinder that the index of the indicator remained for some time in the deepest point. The beginning of turn should be in the area from 60 ° to 90 ° before VMT.
8. The piston of the 1st cylinder costs in VMT if both cams of the 1st cylinder are turned up on a chain of a drive of a camshaft. For control remove a bulk cover and watch cams.
9. At rotation of a cranked shaft include the 5th transfer, release the hand brake and shift the car. Or turn on the hand brake, establish a transmission in neutral situation and turn a pulley of a cranked shaft with a face head for the central bolt.
10. Establish the indicator in situation "0".
11. Take out a cap (1) impellent compartment.
12. Turn a cranked shaft on 2 turns that it was possible to insert a core of OPEL-813 or other suitable core (drill) through an opening in the block of cylinders into an opening in a flywheel.

Prevention

Do not rotate a shaft in the opposite direction, it can lead to the wrong indication of the indicator.


13. Now the indicator should show height of 0,95 ± 0,02 mm at a new chain of a drive of a camshaft.

Prevention

At a chain of a drive of a camshaft after run of 20 000 km the indicator should show 0,90 ± 0,02 mm.


14. If value does not correspond demanded, the pump adjust.
15. Weaken a bolt (3), without unscrewing it. Weaken nuts (1 and 2).

Prevention

Unscrew nuts not strongly, literally on 2 or 3 turns to avoid jamming of a chain of a drive of a camshaft.


16. Turn TNVD until the indicator will not show the correct value.
17. Fix nuts and a bolt from sequence with 1 on 3 with effort of 25 N of m.
18. Remove a verifying core and once again check adjustment. Thus a cranked shaft turn only in the correct direction.

Installation

PERFORMANCE ORDER
1. Clean a verifying core and the indicator.
2. Establish a cap of the block of cylinders.
3. Fix the central bolt with a new sealing ring with effort of 30 N of m.
4. Establish a cover of a bulk mouth.
5. Establish an inlet collector.
Cars with the conditioner
6. Screw the fan with the vyazkostny coupling.
7. Screw the bottom guard of the engine.
8. Connect a cable of weight of the battery.
9. Establish time on hours.
10. Set a protective code of a radio receiver.
11. Start the engine, if necessary pump over injection system.
12. After a trial trip check tightness of the central bolt, if necessary tighten.
