NOTE:
The cylinder bore must be within the specifications for taper and out-of-round before fitting a piston.
- Select a piston size based on the cylinder bore.

NOTE: For precision fit, new pistons are divided into 3 categories within each size range based on their relative position within the range. A paint spot or specific size grade on a new piston indicates the position within the size range.
Choose the piston with the correct paint color or specific size grade.
