- Assign piston to the cylinder bore
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.ⓧ
Cylinder bore diameters are specified in two tolerances. The cylinder bore diameters are differentiated from each other by the identification x or ⓧ. This is located at the bottom right on the crankcase at the mount for engine support.
