Service Magazine, SEPD1428, 24 April 2012, "An Improved Top Piston Ring Is Now Used with the Aluminum Pistons in the 3406, 3408, and 3412 Engines of Certain Machines". Disregard the previous article. Refer to the article that follows.Part number 346-3340 Top Piston Ring is now used for all applications that use aluminum pistons on the engines of the machines that are listed above. The new 346-3340 Top Piston Ring is adaptable back to the first production of the listed engines. The difference between the new 346-3340 Top Piston Ring, and the existing, 134-3761 Top Piston Ring is an increased ring gap of 0.200 mm (0.00787 inch). This increased ring gap allows proper clearance during high temperatures experienced with high load factor applications.All of the 3400 piston cylinder pack prints that include the larger ring gap were updated on July 6, 2010 with an effective date of March 1, 2011. The effective date for cylinder packs built in the United States with the 346-3340 Top Piston Ring was March 15, 2011. Dealers receiving cylinder packs built in the United States with package date codes before March 15 2011 should change the top ring before installing the cylinder packs. Cylinder packs built in
