Pushers are regulated automatically, and do not demand maintenance service. For check of functioning of pushers, warm up the engine, muffle it and uncover a camshaft.
Turn a cranked shaft so that the first cam of a camshaft of cylinder N1 has been directed upwards.
Press a pusher and measure its course. If the pusher course before the valve will start to open, is more 0,2 mm or less than 0,1 mm, it is necessary to replace a pusher. |
