5.3.2. Removal and installation of nozzles
The damaged nozzles can lead to strong blows during the operation of the engine, the damaged bearings reminding operation of the engine with. In the presence of the similar phenomena it is necessary to start the engine on single turns and in turn to weaken cap nuts of pipelines of high pressure. If at an otvorachivaniye of any nut blows disappear, it indicates existence of defect of the corresponding nozzle.
The defective nozzle can be revealed also otvorachivaniy cap nuts during the operation of the engine on rapid single turnovers. If at an otvorachivaniye of any nut the speed of the engine does not change, it indicates defect of the corresponding nozzle. The nozzle is checked by means of the manometer (work HUNDRED).
ATTENTION
The damaged nozzles have to be replaced as their adjustment or repair are not possible.
First signs of malfunction of a nozzle following:
– Defective ignition;
– Knocks in one or several cylinders;
– Engine overheat;
– Falling of engine capacity;
– Excessively black exhaust gases;
– High fuel consumption;
– Dense blue smoke at cold start.
REMOVAL
|
PERFORMANCE ORDER
|
| 1. Clear pipelines of high pressure a cold cleaner. |
|
2. Remove pipelines of high pressure in a set for what weaken cap nuts an open cap key, for example, of HAZET 4560 or VW–3035. |
ATTENTION
Do not turn in pipelines of high pressure. Remove the pipeline surely in a set.
|
|
3. Turn off a bolt of fastening of a nozzle, remove a collar and take out a nozzle. |
ATTENTION
At difficulty with demontazhy nozzles it is possible to use a shock stripper, for example, VW-3364 or HAZET 1966. The auxiliary tool which wells up on a nozzle is necessary for installation of a shock stripper.
|
The auxiliary tool can be manufactured as follows. Cut off the old pipeline of high pressure behind a cap nut at distance about 5 cm. Fix by the soldering on the cut-off end M6 nut.
ATTENTION
Carefully clear the tool. Hit of dirt will lead a nozzle to failure!
|
| 4. Screw the auxiliary tool on the standing still nozzle and establish a shock stripper on the soldered nut. Extend a nozzle. |
| 5. Remove heat-shielding consolidation. |
| INSTALLATION
|
|
6. Surely establish new heat-shielding consolidations between a head of cylinders and a nozzle. Deepening of consolidation has to be turned up, the arrow on an illustration shows towards a head of cylinders. |
| 7. Insert a nozzle into place. |
| 8. Establish a collar of fastening of a nozzle, at the same time you monitor the correct provision of a support. |
| 9. Insert a bolt with a spherical washer and fix by the moment 20 N of m. |
|
10. Fix pipelines of high pressure by the moment of 25 N of m. |
