1 Note the identification of the tolerance groups on the piston crown, check the cylinder diameter and the height of the crankcase. 

2 The tolerances groups for the piston, cylinder diameter and block height should match. 

Normal

Piston

Diameter identification degree = 106BA.

Diameter identification degree = 106BC. 

Compression height degree = 61.36 - 61.40. 

Cylinder

Diameter (Tolerance group) degree = (A) 105.985 - 105.991.

Diameter (Tolerance group) degree = (B) 105.992 - 106.008.

Diameter (Tolerance group) degree = (B) 106.009 - 106.015.

Block height degree = 298.35 - 298.50.

Repair I

Piston

Diameter identification degree = 106, 5BA.
