TM 9-2910-226-34 Section IV. ASSEMBLY OF FUEL INJECTION PUMP FROM SUBASSEMBLIES 3-34. General. a. Assembly of the metering and distributing fuel inject ion pump should be performed in figure number sequence and in accordance with the instruct ions provided with each illustration. b. The fuel injection pump is a precision accessory whose proper operation depends on cleanliness of all parts. Precision lapped surfaces of rotating parts must be free of dust and dirt at all times. During assembly, keep working area, parts, hands, and clothing clean. c. Immediately before assembly, coat all bearings, shafts, and contact surfaces with ap- propriate engine oil. Always use new gaskets and packings. Apply grease, Federal Specification W-P- 236, on tight fitting preformed packings to aid in their installation. 3-35. Repair Kits. a. General. A number of repair kits are supplied to repair the fuel injection pump. Repair kits for the governor linkage, and timing device unit assembly are listed in appendix B. The kits were applied in the previous section during assembly of the individual components.
