Tolerance group identification on piston
Assign piston (1) with corresponding piston diameter (C) and compression height (KH) of the corresponding cylinder bore diameter (B) and crankcase housing height (A). Observe marking on the signature areas (arrows) on the crankcase (2).
Piston diameter cylinder bore diameter
BA A or B
BC B or C
At the next largest oversize of the piston diameter (C) or of the cylinder bore diameter (B), the compression height (KH) at the piston (1) and crankcase housing height (A) is reduced correspondingly.
Piston diameter crankcase housing height
Compression height
BA or B standard
BA 0.3 or BC 0.3 oversize 0.3
BA 0.6 or BC 0.6 oversize 0.6
BA 0.9 or BC 0.9 oversize 0.9
