Pushers are regulated automatically, and do not demand maintenance. 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 the N1 cylinder was directed up.
Press a pusher and measure its course. If the pusher course before the valve will start to open, is more than 0,2 mm or less than 0,1 mm, it is necessary to replace a pusher. |
