THERE IS NO CORE CHARGE ON THE PUMP. The injection pump is a single-plunger mechanical pump which meters and distributes fuel to the injectors in the correct firing order. The pump is driven by the camshaft spur belt or gear at one-half crankshaft speed. All moving parts inside the pump are lubricated by diesel fuel, so the pump is maintenance-free; diesel pumps operate reliably for a long time if clean fuel is used. It is necessary to become familiar with the main components of the VE-type injection pump to understand the basic operating principles. Refer to Figures 1 and 2 for the location of the main components. A VE pump may be gear or spur-belt driven. The drive shaft is connected to a cam plate (K) with a driving disk (I), figure 2. The drive shaft, cam plate, and plunger all rotate together. Note the high spots on the cam plate. These high spots are the face cams and the number of face cams equals the number of engine cylinders. As the cam plate rotates, the face cams contact the rollers causing the cam plate and plunger to move back and forth in the plunger bore. Spring pressure holds the cam plate and plunger agains the rollers. The drive shaft also drives the fuel-supply pump (G) and the governor flyweight drive gear (H). At the bottom of the injection pump is the automatic advance-timing device. As fuel-supply pump presure increases the piston moves the roller ring opposite to driveshaft rotation, advancing injection timing. At the top of the injection pum is a control lever (C), a control-lever shaft (D), and an overflow (retun fuel) valve. Engine idle RPM and maximum speed can be adjusted by the idle-speed adjusting bolt and maximum-speed adjusting bolt. Under the top cover is the governor mechanism.
