Piston Identification

The piston may have an identification mark or the piston
may not have an identification mark for piston placement.
If the piston has an identification mark, follow the directions
for piston placement below. If the piston does not have an
identification mark, the direction for placement of the piston
does not matter.
Note the directional and identification marks when viewing the
pistons from the top. The letter "F", "
be toward the flywheel side of the engine. The other numbers are
used for identification as to diameter, length and design. Four
stroke engine rings have a rectangular profile. See text for oil
control ring upper rail installation. Use the information below to
identify pistons and rings.
