  1. Assign piston to the cylinder bore

    IMPORTANT Piston diameters are specified in two tolerances. The piston diameters are differentiated from each other by the identification x or ⓧ. This is located on the top of the piston crown.

    Pistons marked with x must only be installed in cylinder bores marked with x.

    ⓧPistons marked with x must only be installed in cylinder bores marked with x.ⓧ
