Fuel injection pump
The fuel injection pump is the Bosch “Mine K-type”. It is a
precision piece of equipment machined to close tolerances
and its performance directly affects the performance of the
engine. Therefore, handle it with care.
♦ Handling the injection pump
Use care in handling and using the injection pump. As men-
tioned before, the injection pump is a precision piece of
equipment and care should be taken not to drop it or clamp it
tightly when working on it. Also, he sure to use only clean fuel
that has been filtered. Oil drums left outdoors are always
considered to contain water, so always filter this fuel before
using.
Clean fuel is a must as the fuel is forced through parts of the
pump and nozzle with clearances of 0.0004 in. (1/1000mm)
which may easily he stuck or rusted by even the slightest
amount of water in the fuel.
♦ Installing the injection pump
When installing the injection pump, make certain that the
control rack pin is correctly placed in the 0.2 in. (5mm) wide
groove of the fork ever (1) before tightening the attaching
bolts. Refer to the diagram. If the bolts are drawn down with
the rack pin off the groove, the rack may over travel and stick
in this position. This would cause excess fuel flow, allowing
the engine to overspeed which would result in engine failure.
