    How can we get to know on MAN B&W 2stroke engine whether exhaust valve is rotating or not from outside?

    To test the rotation of the first pull up the indicator rod placed at the top of the exhaust valve and turn it to 90 degree and let it rest on air piston.
    As the air piston moves the indicator will follow its movement. during rotation of the valve spindle, the top position of the indicator will change about 6 mm, because of the groove in the piston.
