POWER CYLINDERS 215
Description
A few changes were made for model year 2004:
• Piston skirts for DT 466 and 570 cubic inch
displacements have a notch cast into each side
of the skirt for piston cooling tube clearance.
• The combustion bowl has been centered within
the piston crown. The pistons are symmetrical,
and therefore do not require orientation.
• Connecting rods have a fractured surface at the
cap and rod bolted joint. These are mated parts
and are not interchangeable with other connecting
rods. It is important that serial numbers on the
connecting rod and connecting rod cap must
match and appear together.
Additional changes running changes were made after
model year 2004:
• New piston cooling tubes were released for
service.
• New connecting rod assemblies were released for
service.
