Before beginning carrying out any works in a head of the block of cylinders, familiarize with the following general information on a design of the mechanism of a gazoraspredeleniye:
- the camshaft having the top arrangement fastens on five bearings;
- the back bearing serves for the axial direction of a camshaft;
- removed on earlier issued engines, for the purpose of engine greasing, the cover of the fourth bearing of a camshaft is established now again and is a usual cover of the bearing;
- before carrying out processing of saddles of valves, surely read the recommendations provided in item 3.3.3;
- the producer in most cases does not specify exact data for gap check in the mechanism of a drive of valves, lengths of klapanny springs in not tension etc. If there are doubts on the specified values, it is necessary to address on HUNDRED Volkswagens where it is possible to receive more exact information;
- plates of klapanny springs, springs and maslootrazhatelny caps are remote, as are in dredging of a head of the block of cylinders;
- at removal of valves pay attention to how these details were established, on an arrangement of pushers, half of a rod of the valve (crackers), plates of the valve, internal and external springs, maslootrazhatelny caps.
