TM 9-2910-226-34 b. The governor housing (TT) is attached to the of the injection pump housing (AC). The main components of the governor are the governor weight and spider assembly (UU, WW), sliding sleeve (VV), governor inner and outer springs (RR, SS), fulcrum lever (NN), and operating linkage. c. The governor weight and spider assembly is pressed on an extension of the camshift (ZZ) and contains two movable governor weights (UU) which are pinned on opposite sides of friction drive spider (WW). The weights swing freely on their pins. d. The sliding sleeve moves freely on the cam- shaft and contains a thrust bearing against which the weight fingers bear. Each side of the sliding sleeve contains a slot to receive the pivot pins of the fulcrum lever. Counterbores at the rear of the sliding sleeve receive the governor inner and outer springs. e. The smoke limit cam (MM) is located at the top of the fulcrum lever (NN) and rides on the stop plate (PP) of the density compensator. The operating lever (F, fig. 1-19 and 1-20) is connected to the operating shaft (E, fig. 1-19 and 1-20). The operating shaft is connected to the fulcrum lever by suitable linkage.

The fuel supply pump assembly consists of the supply pump housing (B), camshaft driven gear (C), drive shaft (D), idler gear (E), housing cover (A), and check valve (G). b. The supply pump housing contains inlet and outlet ports for the flow of fuel. It also houses the check valve which is held in place by the check valve spring (F) and valve screw - (H). - c. The housing cover and cavity in the supply pump housing form a compartment in which the idler gear and drive shaft rotate, The cover also houses the relief valve (J) and spring (K). d. Rotation is imparted by the fuel pump cam- shaft driven gear (C). Figure 1-19. Governor assembly {code B, C, D, E, F and G), rear sectional view. 1-22
