Correct AOE plays a significant role in maximizing the longevity of AEG pistons.

AOE (Angle Of Engagement)

The Angle of Engagement is an angle at which the first tooth of the piston toothing comes into contact with the toothing of the sector gear. If the AOE is incorrectly adjusted, the piston guiding rails and the first piston tooth are subjected to increased wear.

In pistons with metal toothing, this can lead to complete breakaway of the tooth. The correct AOE adjustment significantly increases the lifetime of a piston. There are two ways to perform AOE adjustment – by placing a washer under the piston head, or by using a thicker impact rubber pad on the cylinder head. Both methods move the piston towards the spring guide, lowering the teeth AOE.
