2.6.3. Adjustment of the vacuum block of a turbocharger (the turbocharger is removed)Adjustment
Remove a hose from the vacuum block on a turbocharger (fig. 2.222).

Fig. 2.220. Lock plate of the lever of a turbocharger
|
Remove a lock plate 1 via the lever of a turbocharger (fig. 2.220).

Fig. 2.221. A draft detachment from a turbocharger
|
Previously adjust bypass the valve 1 corrugated nut so that the valve was hardly scrolled by hand (fig. 2.223). By hand twirl a lock-nut.

Fig. 2.224. Installation of the manual vacuum pump
|
Connect the manual vacuum pump, a turbocharger tester to the socket II and the reducing valve, as shown in the figure 2.224. Close the reducing valve the lever 1.
Establish a mobile ring of 1 manual vacuum pump in situation B for "pressure" (fig. 2.225).

|
To include a tester of a turbocharger and install the mobile switch in situation II.

Fig. 2.226. Fixing of the indicator of hour type on a turbocharger
|
Fix a universal support of the indicator of hour type on a turbocharger (fig. 2.226).
|
NOTE
Data in mm belong to an only a few indicator (contains 1 mm of preliminary shift).
|
Fix the indicator of hour type with the extender of 30 mm and the flat probe on a universal support of the indicator of hour type.
Install with a pressure of 0 bars the indicator of hour type on a preliminary tightness in 1 mm.
Turn the index of the indicator of hour type in situation 0.
Check ease of the course of the indicator.
Set the manual vacuum pump in motion until on a tester of a turbocharger value of pressure of 350 ±5 Mbar appears.
The indicator of hour type has to show from 4,1 to 4,3 mm, otherwise follows rotate a corrugated nut until this value is reached.
By hand twirl a lock-nut.
Repeat measurement.
Dump pressure via the reducing valve to 0 Mbar.
Install the indicator of hour type in situation 0.
|
NOTE
The subsequent measurements have to be executed in the specified sequence. Pressure at measurements cannot be lowered to 0.
|
Set the manual vacuum pump in motion until on a tester of a turbocharger value of pressure of 350 ±5 Mbar appears.
Consider an indicator on the indicator and write down it.
Set the manual vacuum pump in motion until on a tester of a turbocharger value of pressure of 650-700 Mbar appears.
Dump pressure via the reducing valve to 350 ±5 Mbar.
Consider an indicator on the indicator and write down it.
Put indicators 1 and 2 and to divide the sum on 2.
The result (average value) has to make 5 ±0,25 mm.
If as a result average value is not equal to 5 ±0,25 mm, follows modify adjustment, tighten a lock-nut by hand and repeat measurement.
If average value is equal to 5 ±0,25 mm, tighten a lock-nut and record it the fixing varnish.
Fix a lock plate 1 over the lever of the vacuum block (fig. 2.220).
