Check and adjustment of the moment of the beginning of injection

Fuel pump of high pressure

1 — a segment spline
2 — a sealing ring
3 — the fuel pump of high pressure
4 — the electromagnetic fuel locking valve
5 — the electromagnetic valve of adjustment of injection
6 — a carving stopper of the pump

For check the indicator with an adapter is necessary for a vvorachivaniye in TNVD. The engine at start has to be cold. Temperature, however, should not be lower + than 20 °C.

 PERFORMANCE ORDER

1. Disconnect a weight cable from the rechargeable battery. The battery is in a luggage carrier behind the right side facing.

 

At a detachment of the battery the memories given in electronic blocks, for example, memories of malfunctions of the engine are erased. Address recommendations of the Section Removal and installation of the rechargeable battery.

4. Screw an adapter (1) (BMW-135330) and the indicator (2) instead of a carving stopper and slightly tighten it. Address an accompanying illustration.

5. Turn the engine clockwise in the direction of VMT of the 1st cylinder so that the index of the indicator for some time stopped in the lower point. The beginning of rotation has to be at least for 60 - 90 ° to VMT. The piston of the 1st cylinder is in VMT if both cams of the 1st cylinder on the party of a driving chain show upward. For a provorachivaniye of the engine include the 5th transfer, release the parking brake and shift the car. Or tighten a brake, establish RKPP in neutral situation and turn a pulley of a bent shaft a head for the central bolt.

Do not turn the engine against the direction of its rotation. It can lead to measurement errors.

9. At a new chain the indicator has to show the course 0.95 ± 0.02 mm.

If the chain has a run over 20 000 km, the indicator has to show the course 0.90 ± 0.02 mm.

10. If value does not correspond to demanded, adjust the pump.

11. Weaken a bolt (3), without turning off it. Address an accompanying illustration.

12. Weaken nuts (1) and (2).

14. Tighten nuts and bolts in the sequence from 1 to 3 moment of 25 Nanometers.

15. Take out a mandrel and once again repeat check. At the same time turn a bent shaft only clockwise.

16. Remove the indicator and take out a mandrel.

17. Insert a stopper into the block of cylinders.

18. Tighten the central stopper with a new sealing ring the moment of 25 Nanometers.

19. Establish a butterdish cover.
