3208 Engines And 3300 Series Engines Equipped With Sleeve Metering Fuel SystemsDescription of Change: A new sleeve bearing is used in the drive end of the fuel injection pump housings used on the above engines. The former sleeve bearing was all bronze. The improved sleeve bearing has steel-backed bronze construction and a slightly larger outside diameter. These changes will produce a tighter fit in the fuel injection pump housings and reduce the possibility of sleeve bearing rotation in the housing.Adaptable As: The new 7W6335 Sleeve Bearing is a direct replacement for the 5P4810 Sleeve Bearing used in fuel injection pump housings for 3208 Engines and 3300 Series Engines with sleeve metering fuel systems.
