Repair Sharan/Sharan Volkswagen>> VR6 engine>> Head of the block of cylinders and valves>> Hydraulic pusher
Cоблюдайте following recommendations:
- after removal it is necessary to establish hydraulic pushers a contact surface down on a pure surface;
- pushers always replace completely as they are not subject to adjustment or repair;
- noise of valves at start-up of the engine is the normal phenomenon. However if it too loud, it is necessary to check pushers, for this purpose:
- start the engine and let's to it work until the cooling fan will turn on;
- increase frequency of rotation of the engine to 2500 mines-1 and let's to it work during 2 mines;

Fig. 53. Check of a hydraulic pusher
|
- if valves still rustle, for definition of a faulty pusher muffle the engine, uncover heads of the block of cylinders and rotate a camshaft so that its cam for a checked pusher looked up. After that press a pusher a piece of plastic or the ground wooden stick
(fig. 53)
. If thus the gap makes more than 0,10 mm before the valve will open, it is necessary to replace a pusher. After installation of a new pusher the engine can be started not earlier than in 30 minutes. Otherwise valves могутстучать on pistons.
