Refer to the Operator and Unit Maintenance Manual for secondary fuel filter assembly maintenance procedures. 3-22. FUEL INJECTION PUMP ASSEMBLY. a. General. The Roosa Master Fuel Injection Pump is mounted on the timing gear case and is gear driven through an idler gear arrangement by the crankcase gear. The end thrust of the fuel injection pump gear and shaft is controlled by a spring loaded thrust button located in the inspection cover on the timing gear housing cover. It is advisable when removing or installing the fuel injection pump that the gear housing inspection cover be removed from the timing gear cover to relieve the spring tension of the thrust button. The fuel injection pump attaching flange holes are elongated to permit accurate adjustment of the fuel pump timing. b.  Removal. CAUTION Thoroughly clean the fuel injection pump prior to removal. Cap or plug all fittings and lines to prevent dirt from entering the pump and fuel system. Failure to observe this caution could result in equipment damage. 3-47
