Fig. 2.170. Installation of adaptation with a suspended fork
Twist adaptation with a suspended fork in the directing plate for engines of 2,0 l and 3,0 l of FSI (fig. 2.170)
Insert an adjusting cartridge into the directing plate for engines of 2,0 l and 3,0 l of FSI.
Suspend a press fork to adaptation.
On the party of release the press fork should be suspended, as shown in the figure 2.170.
Press an adjusting cartridge down. At the same time you twist the screw with a nakatka of the adjusting boss to the right until the ends enter valve crackers.
Slightly turn the screw with a nakatka forward and back, at the expense of it crackers of the valve are unclenched and the boss is captured (fig. 2.171)
Release a press fork.

Fig. 2.173. Vypressovka of a pin and removal of a nozzle
If because of shortage of the place the stripper for oil scraper caps to a vypressuyta is not possible to use, a pin a drift and remove a nozzle (fig. 2.173)
Put the lower part of a stripper of oil scraper caps to an oil scraper cap.

Take the plastic plug A.
Insert a spring and a plate of a valve spring.
After extraction of crackers of the valve from the adjusting boss at first they need to be inserted into adjusting adaptation (fig. 2.176).
Press an adjusting cartridge from above on adjusting adaptation and remove valve crackers.
Press an adjusting cartridge by means of a press fork down and twist the screw with a nakatka adjusting the boss back and forth, at the same time to extend it up.
Unload a press fork at the extended screw with a knurled head.
Remove the device for installation.
Further installation and assembly is carried out in the return to sequence removal.
