The design of hydraulic pushers does not assume any adjustments in use of the engine. However, if in the course of work excessive noise is heard, they can be checked as follows:

– start the engine and warm up it up to the working temperature;

– switch off the engine and uncover a head of the block of cylinders (see section 3.3.15);

– turn a bent shaft of the engine for a bolt of fastening of a pulley of a bent shaft so that the cam of the camshaft of the first cylinder was directed up;

– using the measuring probe, check a gap between the basis of a cam and a hydraulic pusher and if a gap of more than 0,1 mm, then the hydraulic pusher is faulty and is subject to replacement;

– if the gap is less, than 0,1 mm, using the wooden or plastic tool, press the top part of a hydraulic pusher so that he contacted with the top part of a core of the valve;

– if the course of a hydraulic pusher is more, than 1 mm, a hydraulic pusher is faulty and is subject to replacement.

PREVENTION After installation of hydraulic pushers do not start the engine within at least 30 min., otherwise there can be an impact of pistons to valves.
