I cannot tell from the picture, but, is your engne sitting on the engine stand horizontal or vertical. If it is sitting horizontal - as you turn the crankshaft the shaft will move forward and back a few thousands of an inch -the distance of the thrust movenent in the shaft. This affect the measurments in your dial indicator.


Turn the engine vertical or at least 45 degrees so all the thrust is moving down. The shaft will ride against the thrust surface of thebabbit and you will get a more consistant dial reaaduing.. clear as mud??? ken
