3.5. Combining Governor and Pump Bodies Turn the link lifter plate counterclockwise. and install the governor body to the pump bodies Install the new packing. Do not confuse front with rear surface. Assemble it, while aligning bolt holes with those on the body. Rack Link Link lifter a) During assembly b) During operation Attaching governor CMP Be careful not to bend or damage the governor case packing (GRC). (It is not reusable. If it sticks to the packing surface, remove it without giving damage to the surface of the packing.) Direct the link lifter as shown in Fig.
a) shown below, where the semicircular section is positioned at the lower side, and bring governor CMP to the pump body until the link comes into contact with the rack. At this time, be careful that the link does not hit the pump body. (If the link hit the pump body severely, check that the link is not bent or deformed.) Direct the link lifter as shown in Fig. b) shown below, where the semicircular section is positioned at the upper side, and engage the rack and the link with each other. At this time, if it is difficult to engage the rack and the link with each other, assemble them while pushing the governor lever to the decreasing side (when mechanical governor is used).
After putting the link lifter in the state shown in Fig. b), pull the governor CMP a little to check that the link and rack are engaged with each other. (Be sure not to pull governor CMP excessively). (If the barrel plug is not installed yet, the following method can be used to check the plunger rotation. Mechanical governor: Push the governor lever to the decreasing side through the solenoid attaching hole. New ECO governor: Push the rack to the increasing side through the rack inspection port.) Be sure to tighten the link lifter securing bolt. (T = 8 to 10 N - m) 40
