Front Accessory Drive Group Changed; New Drive Parts For Fuel Transfer Pump
Usage:

Description of Change: Changes have been made to the front accessory drive group and the fuel transfer pump group on the above models. In the accessory drive group, the adapter and dowels are removed from the gear assembly for the transfer pump, and the gear (only) is now used in the group. At the same time, a new fuel transfer pump group has the existing fuel transfer pump group as a component, plus a new coupling assembly and shaft. The new coupling assembly and shaft fit in place of the former adapter which was part of the accessory drive gear assembly. The new drive parts will give longer service life.
Adaptable As: Direct replacement when the necessary parts are used together.
