The size group number is stamped on each part and corresponds to a specific size range of a new part. For used parts, this size group designation is not valid.
Repaired or used parts must be measured with a micrometer. By comparing the table data with the measurement results, determine the size group of the part.
Information on standards, methods of measurement and selection of parts is provided in the text of this instruction.
Piston
When using a new cylinder block
Determine the cylinder size group using the mark located on the rear left side of the block (L) and select a piston of the same size group.
A. Corrective spump.
B. Standard stamp.
C. Dimensional group of the first cylinder bore.
D. Size group of the second cylinder bore.
E. Dimensional group of the third cylinder hole.
F. Dimensional group of the fourth cylinder bore.
G. Dimensional group of the main bearing bed of the dispute No.1.
H. Dimensional group of the main bearing bed, dispute No.2.
I Dimensional group of main bearing bed spores No.3.
J. Dimensional group of the main bearing bed, dispute No.4.
K. Dimensional group of the main bearing bed, dispute No.5.
L. Location of size groups. The arrow indicates the front side of the engine.
Note: If there is a correction stamp on the cylinder block, these values should be used as they are more in line with reality.
