Engine News SEBD9949, 27 June 2014, "An Improved Guide Spring and Valve Lifter Assembly Are Used in Certain C-9, C9 ACERT Engines, and C9.3 ACERT Engines". Disregard the previous article. This article has been updated to reflect updates to the effectivity.ReferenceReuse And Salvage Guidelines, SEBF9008, "Reworking the Cylinder Block for Better Alignment of the Lifter Follower Clip"ReferenceReuse And Salvage Guidelines, SEBF9008, "Reworking the Lifter Bores After a Lifter Lock Failure on 3400 Series Engines"ReferenceReuse And Salvage Guidelines, SEBF8069, "Procedure to Repair Lifter Bores in 3300 and 3400 Series Engines"The new 453-6003 Guide Spring and 453-5998 Valve Lifter As have been improved to reduce rotation and to add additional strength during engine operating conditions. The new 453-6003 Guide Spring and 453-5998 Valve Lifter As are a direct replacement for the existing 384-4171 Guide Spring and 384-4172 Valve Lifter As .Note: The new 453-5998 Valve Lifter As has a dull gray finish as opposed to more polished finish of the 384-4172 Valve Lifter As. The dull gray finish is due to an additional heat treatment which adds strength to the lifter.
