Main Components
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. Mounted outside the distributor head is a delivery valve (N) for each cylinder, fuel-cut (fuel shutoff) solenoid, and an air-bleed screw in the center.
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.
