Turn out bolts of fastening of a pressure plate, disconnect vacuum hoses and remove valves from the air filter (pic. 14.31).
A vacuum pump must be used to check the valve. Connect the valve with a piece of tubing, then slowly increase the vacuum and check that the valve begins to open at a pressure of 70-90 mmHg. Art.
