7. FUEL INJECTION PUMP/GOVERNOR
7.1 Introduction
t is described about the features of the fuel injection
pump, disassembly, assembly and adjustment pro-
cedure.
Fuel injection pump is the most important equip-
ment, which is enable to make the sensitive adjust-
ment according to the variable load of the engine.
Therefore all of the parts are required not only very
precise machining but also finest, assembling with
top level.
The careful arrangement of keeping off the dust and
the rust when disassemble, adjustment and reas-
semble of the fuel injection pump is made in the
market.
The fuel injection pump is a distributor type pump which is unified of Mono-plunger, a distributing shaft, a
hydraulic head which equipped the delivery valve for each cylinder, pump housing which has a cam shaft inter-
