Selection

Note: The cylinder bore must be within specifications for taper and out-of-round before fitting a piston.





1. Select a piston size based on the cylinder bore.





2. Note: For precision fit, new pistons are divided into three categories within each size range based on their relative position within the range. A paint spot on the new pistons indicates the position within the size range.

Choose the piston with the proper paint color.
^ Red-in the lower third of the size range.
^ Blue-in the middle third of the size range.
^ Yellow-in the upper third of the size range.
