2.6.3. Adjustment of the vacuum block turbocharger (турбонагнетатель it is removed)Adjustment
Remove a hose from the vacuum block on турбонагнетателе ( fig. 2.222).
|
Fig. 2.220. A lock plate of the lever turbocharger
|
Remove a lock plate 1 through the lever turbocharger ( fig. 2.220).
|
Fig. 2.221. A detachment of draught from turbocharger
|
Preliminary adjust bypass the valve 1 corrugated nut so that the valve was hardly scrolled by hand ( fig. 2.223).
By hand twirl a counternut.

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

|
To include a tester turbocharger and establish the mobile switch in position II.

Fig. 2.226. Fastening of the indicator of hour type on турбонагнетателе
|
Fix a universal support of the indicator of hour type on турбонагнетателе ( fig. 2.226).
THE NOTE
Data in mm concerns to считанному to an indicator (contains 1 mm of preliminary displacement).
|
Fix the indicator of hour type with the extension piece of 30 mm and flat probeом on a universal support of the indicator of hour type.
Establish at pressure 0 bar the indicator of hour type on a preliminary tightness in 1 mm.
Turn the index of the indicator of hour type in position 0.
Check up ease of a course of the indicator.
Actuate the manual vacuum pump while on a tester turbocharger there will be no value of pressure 350 5 мбар.
The indicator of hour type should show from 4,1 to 4,3 mm, otherwise follows rotate a corrugated nut until the given value will be reached.
By hand twirl a counternut.
Repeat measurement.
Dump pressure through редукционный the valve to 0 мбар.
Establish the indicator of hour type in position 0.
THE NOTE
The subsequent measurements should be executed in the specified sequence. Pressure at measurements cannot be lowered to 0.
|
Actuate the manual vacuum pump while on a tester turbocharger there will be no value of pressure 350 5 мбар.
Consider an indicator on the indicator and write down it.
Actuate the manual vacuum pump while on a tester turbocharger there will be no value of pressure 650–700 мбар.
Dump pressure through редукционный the valve to 350 5 мбар.
Consider an indicator on the indicator and write down it.
Combine indicators 1 and 2 and to divide the sum on 2.
The result (average value) should make 5 0,25 mm.
If as a result average value is not equal 5 0,25 mm, follows modify adjustment, tighten a counternut by hand and repeat measurement.
If average value is equal 5 0,25 mm, tighten a counternut and fix its fixing varnish.
Fix a lock plate 1 over the lever of the vacuum block ( fig. 2.220).
