Construction and Handling
Fuel System

the cartridge type shown schematically in
flowing in the direction indicated by the arrows To bleed air Fig 2 Under normal conditions it should oly have to be

Fuel injection timing
Fuel injection timing is adjusted by changing the number of
shims used between the pump and the gear case it fits into See
1 Fuel tank 6 Nozzle holder Fig 3 One shim corresponds to approximately 5degrees in

Fuel injection pump Handling the injection pump
The inJPctioll pump is the Bos h MiIlP K typ It is a prpi Use care in handling and using the injection pump As men
sinn pit1CC of cqIJinmrnt milChirucJ III rlOSf tolerances and its tinned before the injection pump is a precision piece directly affect the of
the engine equipment and care should be taken not to drop it or clamp it
Therpfore handle it with carl tightly when working on it Also be sure to use only clean
fuel that has been filtered Oil drums left outdoors are always
ronsidered to contain water so always filter this fuel before
using
Clean fuel is a must as the fuel is forced through parts of the
pllmp and nozzel with clearances of 00004 in 11000mm
which may easily be 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 corrertly placed in the 02 in 5mm wide
groove of the fork lever 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

Good Bad Oil pump pickup screen
The oil pllmp pickup is located in the crankcase as shown in
Fig 9 and is fitted with a metal screen If the screen becomec
plugged wash it off with diesel fuel or kerosene
pftAZI Lubrication system
The entire lubrication system is illustrated in Fiq 8 Oil from
the pump is forced through the replaciable parer element
4 filter The filter is equipred with a pressure regulated valve to
6 keep the pressure through the filter at 6471 psi 455
kgfcm 2 From the filter part of the oil goes to the crankshaft
to lubricate the crankpins and the remainder goes to lubricate
the rocker arms
An oil prfSsure switch is located in the passage from the filter
and controls the oil pressure If the oil pressure falls below
14 psi 10 kgf cm 2 the oil warning lamp will light on the
7 Pressure spring 4 Nozzle body dash panel If the oil pressure lamp stays on after the engine
2 Pressure pin 5 Needle valve is running at normal speed shut the engine off immediately
3 Pressure pin holder 6 Nozzle piece Find and correct the cause of the low oil pressure before
operating again
Fig 7 Nozzle If the pressure regulating valve in the filter fails and the
pressure rises a safety valve will limit the pressure to 140 psi
10 kgf Icm 2
Probable cause of low oil pressure n
1 Clearance on one of the hearings is to great
2 One of the rocker arms is too loose
