3500 and 3500B Engines with Standard DisplacementEngine News SEBD9327, November 2003, "Introduction of New Pistons and Remanufactured Cylinder Packs". Disregard this article. The pistons in this article have been cancelled and replaced with new pistons. Refer to the following article for the correct information.Description of Change:
Illustration 1 g01026917
A new piston has been introduced for 3500 Engines. The forged steel piston is a one-piece piston. A large circumferential slot separates the crown and the skirt. The crown and the skirt remain attached by the strut for the pin bore. The new top ring is steel and very sensitive to bending. The ring expander tool must be used in order to install the top ring. Failure to use the ring expander tool will result in early hour failure of the piston ring. This will result in engine failure. Refer to table 1 for the part numbers of the tools that are used in servicing the piston.

1P-1861 Retaining Ring Pliers
1U-7616 Piston Ring Compressor Gp Adaptable To: The new pistons are a direct replacement for previous pistons that are used in 3500 Engines. The new pistons have the same balance weight as the previous pistons. The new pistons can be used in the same engine with the previous pistons. Table 2 lists the usage of the new piston and rod groups and the former piston and rod groups. The new remanufactured cylinder packs that include the new piston and the former remanufactured cylinder packs are also listed.Note: The diameter of the eye in the connecting rod has not changed.Note: The new piston cannot be used in 3500B High Displacement Engines.
