  • Description of Change: A new fuel transfer pump is being used in 3500 Diesel Engines. A portion of the new pump housing is cast in a single continuous section. The former pump used separate sections. Refer to Illustrations 1 and 2.

    The mounting bolts for the new pump have changed. Refer to Tables 1 and 2.

    Adaptable To: Three part kits are available for the new fuel transfer pump. The 255-8691 Seal Kit is a service kit for the seals and for the gasket. The 255-8692 Repair Kit is a service kit for the gear and for the shaft. The 256-8766 Repair Kit is a service kit for the bypass valve. Refer to Table 2.

    The new 255-8113 Fuel Transfer Pump Gp is a direct replacement for the former 225-4260 Fuel Transfer Pump Gp. The new pump is adaptable to all 3500 Diesel Engines. Table 3 lists the serial number effectivity for 3500 Diesel Engines.
